General Specifications
   Other Transformer Types / Applications       
   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. 
   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 small changes to a voltage. Typical usage is for distribution, power, or power supply transformers. 
   Digital Transformer       Digital transformers are used in audio applications to isolate the signal and match impedances. 
   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. 
   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 flyback - 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 CRTs. 
   Electronics Transformer       Current or voltage transformers used as measuring instruments in the electronics industry. 
   Impedance Matching Transformer       Impedance matching transformers are used to interface two different devices or circuits in order to provide common impedance. In general, these types of transformers have a 1:1 turn ratio. 
   High-Voltage Transformer       High-voltage transformers are used in situations where a high voltage is needed. 
   High Frequency Transformer       Transformers used in high-frequency applications. 
   Interface Transformer       Interface transformers are used in communications applications where the signal is isolated. 
   Trigger / Gate Drive Transformer       Trigger transformers are used to drive high-speed switching devices, such as FETs and IGBTs. They are commonly used in applications like switching power supplies. 
   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 levels. 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. 
   Single Phase Transformer       These are transformers that operate with single phase voltage. 
   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. 
   Telecom / LAN Transformer       Telecom transformers are used in applications that require high bandwidth and fast switching speeds. The signal is isolated between the primary and secondary grounds. 
   Encapsulated Transformers       Encapsulated transformers have a protective coating of cured plastic or other encapsulant which encloses the unit and provides weatherproofing. 
   Other       Other unlisted, specialized, or proprietary transformer type.

   Topology / Configuration       
   Your choices are...         
   Boost       Boost or step-up transformers are used to convert a lower DC input voltage to a higher DC output voltage of the same polarity. 
   Forward (Buck) Transformer       Buck or step-down converters are used to convert a higher DC input voltage to a lower DC output voltage of the same polarity. Forward converters are similar to buck-boost converters, but use a transformer to store energy and provide isolation between the input and output. The difference between flyback and forward transformers is in the way the energy transfer takes place. Flyback transformers have two distinct phases for energy storage and delivery. By contrast, forward transformers transfer energy from input-to-output in a single step. 
   Flyback       Flyback transformers are a topology that uses the flyback - also known as kickback - of an inductor to convert the input voltage to the transformer at 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.

   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 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.

   TNC       Threaded Neil-Concelman (TNC) connectors are similar in size to BNC connectors, but feature a threaded coupling nut for applications that require performance to 11 GHz. TNC connectors are durable, reliable devices that are widely used in the cellular and mobile communication industry for equipment cabling and antenna interfaces. 
   Type F       Type F connectors have a screw-type coupling and frequency range up to 1.5 GHz. Applications include CATV, TV, and antennas. 
   Type N       Type N connectors include an integrated gasket to protect against environmental ingress and create an air gap between the center and the outer conductor. They primarily have 50 Ω impedance, but 75 Ω versions for CATV are available. 
   UHF       Ultra high frequency (UHF) connectors are economical, all-purpose connectors designed with non-constant impedance for use in comparatively low voltage and low frequency applications, such as citizens' band (CB) communications systems. UHF connectors are also used in public address systems, closed circuit television (CCTV), civil defense, landing systems, ground control apparatus, ship-to-shore communications, and mobile radio equipment hookups between antenna and transmitters or receivers.
