General Specifications
   Type       
   Your choices are...         
   Chip Inductor       Chip inductors contain coils made of semiconductor materials. Some inductors that are called "chips" do not use semiconductor materials.   
   Other       Other unlisted device types. 
   Standard Inductor, Coil, Choke       Inductors are passive components that resist changes in electrical current and store energy in a magnetic field. They are also called AC resistors, coils, and chokes. The changes in an inductor's magnetic field induce a voltage that opposes the field-producing current. This property, inductance, impedes changes in current. With inductors, the induced voltage is proportional to the inductance value and to the rate of current change. 
   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. 
   Chassis Mount       Chassis mounted devices bolt onto a chassis, typically in a metal-to-metal configuration for better heat dissipation.  
   Other       Other unlisted mounting styles.

General Performance
   Inductance Range       Inductance range is the range of inductance, the property of a circuit element to oppose any change in the flow-through of current. Inductance is influenced by an inductor's core material, shape and size. The turn count and shape of the coil are also important factors. The unit of inductance is the Henry (H). 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Inductance Tolerance       Inductance tolerance is the allowed amount of variation from the nominal value as specified by the manufacturer. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Rated DC Current       The rated DC current (DC) is the level of continuous direct-current that can be passed through the inductor without damage. The DC-current level is based on a maximum temperature-rise at the maximum-rated ambient temperature. The rated current is related to the inductor's ability to minimize power losses in the winding by having a low DC resistance.  For low-frequency currents, the RMS current can be substituted for the DC-rated current. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   DCR       Direct current resistance (DCR) is the resistance of the inductor winding as measured using DC current. DCR is usually minimized in the design of an inductor, and specified as a maximum rating. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   SRF       Self resonant frequency (SRF) is the frequency at which an inductor's distributed capacitance resonates with its inductance. Because inductance equals capacitance, the values cancel each other out. An inductor at SRF acts as a purely resistive high-impedance element and has a Q-value of zero. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Operating Temperature       This is the full-required range of ambient operating temperature. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Standards and Certifications
   RoHS Compliant       Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   WEEE Compliant       Waste Electrical and Electronics Equipment (WEEE) is a European Union (EU) directive designed to encourage the reuse, recycling and recovery of electrical and electronic equipment. WEEE seeks to improve the environmental impact and performance of such equipment, and establishes requirements and criteria for collection, treatment, recycling and recovery. In addition, WEEE makes producers responsible for financing such activities. For their part, retailers and distributors must provide a way for consumers to return used or obsolete equipment without charge. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
