   Electrostatic Capacitors      The insulating material between the plates of the capacitor. This material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. This material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields.
   Your choices are...         
   Air       The dielectric medium is air. Typically, these devices are used in high voltage applications. 
   Ceramic       Capacitors have a solid body made of high-temperature, ceramic resistive material with bonded metal contacts. 
   Ceramic COG (NPO)       Ceramic COG (NPO) capacitors have a high Q, low K, temperature-compensated dielectric and stable electrical properties under varying voltage, temperature, frequency and time. They are suitable for low-lost circuits and for timing and tuning applications. There are several unofficial, colloquial temperature coefficient designations for capacitors. The temperature coefficient is given as P for positive and N for negative, followed by a 3-digit value in ppm/°C. For example, P100 is +100 ppm/°C and N220 is -200 ppm/°C. The exception to this system is NPO where the letter “O” instead of the number “0” is used; however, the term NP0 is not uncommon. Both NPO and NP0 indicate that the capacitor is stable with temperature. 
   Ceramic X7R       Ceramic X7R (BX) capacitors have moderate K values and are temperature-stable. They exhibit moderate changes in electrical properties under conditions of changing temperature, voltage, and frequency. X7R capacitors are suitable for bypass, coupling, and frequency discrimination circuit applications. X7R capacitors exhibit no more than 15% capacitance deviation over a -55 °C to +125 °C temperature range.

Capacitance measures the ability to store energy, given as C = K A/D, where A is the area of the electrodes, D is their separation, and K is a function of the dielectric between the electrodes. The formula yields a result in farads (F), but a farad is so large that the most commonly used values are expressed in microfarads (µf = 10-6F) or picofarads (pf = 10-12F)

Packaging Specifications
   Lead / Termination Type:       
   Your choices are...         
   Surface Mount Technology (SMT)       Devices that use surface mount technology (SMT) do not have leads. Instead, they are pad-mounted. 
   Axial Leads       Axial leads extend from the ends and along the axis of the resistor, capacitor, or other axial part. They do not extend from the sides.   
   Radial Leads       Radial leads extend from the sides instead of from the ends.  
   Flying Leads       Flying leads project horizontally. 
   Tab Leads       Tab leads are terminals that are designed for direct mounting into a circuit board socket. 
   Screw Leads       Capacitor leads are designed to be fastened with screws. 
   Gull Wing Leads       Gull wing leads are used widely because they are relatively inexpensive to mold and form. Gull wings are flexible and can withstand thermal expansion and contraction. It is easy to inspect the integrity of gull wings leads to circuit board solder connections. 
   J-Leads       J-leads are popular because they use less PCB real estate than gull wing leads; however, the J-lead to board solder connections are hidden from inspection and the leads are more difficult to form. 
   Other       Other unlisted lead types. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Mounting Style       
   Your choices are...         
   Through Hole Technology (THT)       Through hole technology (THT) mounts components on a printed circuit board (PCB) by inserting component leads through holes in the board and then soldering the leads in place on the opposite side of the board. 
   Surface Mount Technology (SMT)       Surface mount technology (SMT) adds components to a printed circuit board (PCB) by soldering component leads or terminals to the top surface of the board. SMT components have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads.   Industry-standard pick-and-place equipment can mount SMT components quickly, accurately, and cost-effectively. SMT is a widely used alternative to mounting processes that insert pins or terminals through holes and solder leads into place on the opposite side of the board. 
   Bolt Mounted       The capacitor is mounted by bolting in place. A bolt is a threaded fastener, with a head. Normally a nut is used to secure the bolt. 
   Bracket Mount       Capacitor either requires or comes with bracket for mounting. A bracket is a support or fixture to hold something up. In a bracket mounted capacitor, the bracket can be bolted. 
   Pole Mount       Devices mount on poles and require special pole-mounting brackets. 
   Other       Other unlisted mounting types.

   Packing Method       
   Your choices are...         
   Tape Reel       Components are packed in tape reel assemblies that include a carrier tape with embossed cavities for storing individual components. A cover tape seals the carrier tape in place. This composite tape is then wound on a reel that is placed in a corrugated shipping box for transport and delivery. Customers unpack the reels and load them into industry-standard, pick-and-place board assembly equipment. Tape and reel assemblies provide component isolation and are designed for surface mount packages such as quad flat package (QFP) and thin quad flat package (TQFP).    Typically, carrier tape is made from a polystyrene (PS) or PS-laminate film with a uniform film thickness between 0.2 mm to 0.4 mm. Carrier tape design is defined largely by component length, width, and thickness. Cover tape is made from a polyethylene teraphthalate (PET) film or film laminate with an adhesive applied to the underside of the film. This adhesive is usually heat and pressure sensitive to ensure a positive, consistent seal between the carrier tape and the cover tape. The reels that contain the composite tape are typically made of polystyrene and have one, two, or three parts. Reel dimensions meet EIA-481-1, EIA-481-2, and EIA-481-3 standards. 
   Tray / Rail       Components are packed in trays (rails) that are made of carbon-powder or fiber materials and molded into rectangular outlines that contain matrices of uniformly spaced pockets. These containers protect components during shipping and provide proper component location and orientation for use with industry-standard, pick-and-place board assembly equipment. Trays are designed for components for that have leads on four sides and that require component lead isolation during shipping, handling, or processing. For example, quad flat package (QFP) and thin quad flat package (TQFP) components are often shipped in trays. To facilitate shipping and handling, trays are stacked and bound together in standard configurations. To provide rigidity, an empty cover tray is added to the top of the load. Typical stacking configurations consist of five full trays and one cover tray, and ten full trays and one cover tray. Customer requirements determine whether trays are shipped in single or multiple stacks. 
   Shipping Tube / Stick Magazine       Components are packed in shipping tubes or stick magazines that are made of rigid polyvinylchloride (PVC) and extruded in industry-standard sizes. These containers protect components during shipping and provide proper component location and orientation for use with industry-standard, pick-and-place board assembly equipment.  To facilitate shipping and handling, shipping tubes and stick magazines are usually loaded into intermediate containers such as boxes or bags to form standard quantities. Intermediate-level packing quantities for shipping tubes and stick magazines often vary by pin count and package type. 
   Bulk Pack       Components are distributed as individual parts. 
   Other       Other unlisted, specialized or proprietary packing methods.
