General Specifications
   Transformer Type       
   Your choices are...         
   Audio Transformer       Audio transformers are ideally suited for voice and data transmission. The frequency response of these transformers typically ranges from 300 Hz to 20 kHz. 
   Autotransformer       Autotransformers are a special type of power transformer that only has one winding. By tapping or connecting at certain points along the winding, different voltages can be obtained. Autotransformers are generally used in low-power applications. 
   Balun Transformer       Balun transformers are used to interface a balanced line (two conductors carrying equal currents in opposite directions) to an unbalanced line (one conductor carrying current and a ground).  Its name is derived from the terms applied to BALanced to UNbalanced lines. 
   Buck-Boost Transformer       Buck-boost transformers are used to make little changes to a voltage. Typical usage is for distribution, power, or power supply transformers. 
   Current Sense Transformer       Current sense transformers are generally used to detect and measure current. There are two basic types of current sense transformers: those designed and used to precisely measure current in accurate instrumentation applications, and others designed and used in switch-mode power converter type applications.  In power conversion applications, current transformers are used to measure trends, peak values, and average values rather than absolute values. As a result, these devices do not need to have a very high degree of accuracy, but rather need to be efficient, dense, and exist in many shapes and styles capable of supporting all traditional types of manufacturing processes. 
   Digital Transformer       Digital transformers are used in audio applications to isolate the signal and match impedances. 
   Electronics Transformer       Current or voltage transformers used as measuring instruments in the electronics industry. 
   Encapsulated Transformers       Encapsulated transformers have a protective coating of cured plastic or other encapsulant which encloses the unit and provides weatherproofing. 
   Flyback Transformer (FBT)       Flyback transformers (FBT) or line output transformers (LOPT) are transformers that are designed to produce a very high output voltage (normally in the order of kilovolts) from a relatively low input voltage. Flyback is a topology that uses the flayback - also known as kickback - of an inductor to convert the input voltage to the transformer to a desired output voltage.  This is done by first storing the input energy (in the inductor) produced by the input voltage (this is called the charging cycle), and then transferring this energy (this is called the discharge cycle) to the output. They are commonly used to generate high voltage to drive CRT's 
   High Frequency Transformer       Transformers used in high-frequency applications. 
   Interface Transformer       Interface transformers are used in communications applications where the signal is isolated. 
   Lighting Transformer       Lighting transformers are used to provide suitable power to lights and lighting systems. 
   Medical Transformer       A transformer used in medical applications such as biomedical equipment in hospitals. There are many strict safety rules, guidelines and laws governing the design, construction and use  of these transformers. 
   RF Transformer       RF transformers are low-power devices normally used for impedance matching that operate over the radio frequency or microwave spectrum. 
   Rectifier Transformer       Rectifier transformers produce a DC current or voltage. They are drive a diode or a thyristor, and they are used in electrolysis and smelting applications. 
   Resonant Transformer       Resonant transformers operate at the resonant frequency of one of its coils (the primary or the secondary). They are used for arc welding, discharge lamps, etc. 
   Telecom / LAN Transformer       Telecom transformers are used in applications that require high bandwidth and fast switching speeds. The signal is isolated between primary and secondary grounds. 
   Planar Transformer       The winding of a planar transformer are patterns on a printed circuit board (PCB). 
   Power Transformer       Power transformers convert one voltage to another at high power level. Power  transformers  are  used  in  electronic circuits  and come  in  many  different  types  and applications. Power transformers are sometimes considered to be those with ratings of 300 volt-amperes and below.  These transformers normally provide power to the power supply of an electronic device, such as in power amplifiers in audio receivers. 
   Pulse Transformer       Pulse transformers interface a pulse forming network (PFN) and a load. They match the impedance of the load to the PFN in order to maximize power-transfer efficiency. 
   Switch Mode Transformer       Switch mode transformers or switching transformers are used  in switching power supplies and DC-DC converters. These transformers provide the energy storage element to transfer energy from input-to-output in discrete packets that are required in switching power supplies, regulators, or converters. 
   Trigger / Gate Drive Transformer       Trigger transformers are used to drive high-speed switching devices, such as FETs and IGBTs electronics. They are commonly used in applications like switching power supplies. 
   Variac / Variable Autotransformer       A variac is an autotransformer with sliding tap. They are also known as variable autotransformers. 
   Other       Other unlisted, specialized, or proprietary transformer type.

   Package Type:       
   Your choices are...         
   Connectorized       Connectorized devices attach with coaxial or other types of connectors. 
   Flat Pack (FPAK)       Flat pack (FPAK) devices have gull wing or flat leads on two-or-four sides. They provide exceptional thermal and electrical performance and are available in cavity-up and cavity-down configurations. Flat pack devices are typically ceramic, hermetic, and surface-mounted. They are available in a variety of body sizes and pin counts. 
   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. The PCB pad is typically 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.  
   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. 
   Waveguide Assembly       Waveguide assemblies are used in microwave waveguide systems. They consist of a hollow, metallic conductor with a rectangular, elliptical, or circular cross-section. Some conductors contain solid or gaseous dielectric materials. 
   Other       Other unlisted, specialized, or proprietary package.
