General Specifications
   Winding Turns       
   Your choices are...         
   Step-Up Transformer       In step-up transformers, the secondary voltage is larger than the primary voltage. 
   Step-Down Transformer       In step-down transformers, the secondary voltage is smaller than the primary voltage. 
   Variable       The transformer has a setting to change the turn ratio as needed. 
   One to One       The transformer ratio is 1:1, or near 1:1. 
   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.
   Other Transformer Types / Applications       
   Your choices are...         
   Three Phase / Polyphase Transformer       In polyphase (3-phase) transformers, the three primary windings are connected together and the three secondary winding are also connected together. 
   Single Phase Transformer       These are transformers that operate with single phase voltage. 
   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 / Form Factor       
   Your choices are...         
   Chassis Mount       A chassis-mounted transformer has tabs to facilitate screwing it down. 
   Chip Transformer       Chip transformers have a form factor of an integrated circuit (IC) chip. They are typically manufactured using thin-film technology. 
   Dish / Disk Mount       A simple rubber washer and metal disk or dish secures the transformer to the chassis or board. There is usually a through-hole in the middle of the disk that allows for a screw to hold the transformer down. 
   H-Frame       H-frame mounting is used in applications where high vibration or shock is present. It is an "H" shaped frame that the transformer sits on. The frame is secured to the chassis or board. 
   Modular Jack       Magnetics incorporated into the RJ-45 form factor insure high common mode noise immunity, while maintaining signal integrity. 
   Pad-Mounted       Pad-mounted transformers are mounted on the ground, sitting on a concrete (or other material) pad. They are normally step-down transformers used in power distribution systems to step down the voltage from the high voltage terminals of an underground distribution system to the low voltage of the end user’s needs. 
   PC / PCB Mount       Any of a variety of signal transformers mounted on PCBs. They can either be of surface-mounted or through-hole configurations, using the soldering method to hold the transformers. PC mount transformers offer a small footprint for the design engineer looking to measure sensor current or voltage on a computer board. Some applications for PC or PCB transformers include sensing current overload, ground fault detection, metering, isolated current feed-back signal in switch mode power supplies, motor current load / overload, lighting, switch controls, ultra-sound current, high resolution sonar current, and isolated bi-directional current sensor with full wave bridge. 
   Pole-Mounted       Pole-mounted transformers are installed on top of poles and are normally used as distribution step-down transformers servicing houses located close by. 
   Other       Other unlisted, specialized, or proprietary transformer mounting techniques. 
   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.

Performance Specifications
   Operating Frequency Range       The frequency range for which the transformer will meet all guaranteed specifications. 
   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.
   Maximum Primary Voltage Rating       The maximum primary voltage rating is the input voltage range of the transformer. Transformers for use with several nominal voltages need more than one primary winding. Enter the maximum voltage required for the application. Matching products will list all primary voltages available in addition to the maximum specified. 
   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.
   Maximum Secondary Voltage Rating       The maximum secondary voltage rating is the output voltage range of the transformer. A transformer may provide more than one secondary voltage. Enter the maximum voltage required for the application. The matching products will list all secondary voltages available in addition to the maximum specified. 
   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.
   Maximum Secondary Current Rating       This is the rated output 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.
   Power Rating (VA)       The rated power of the transformer is the sum of the VA (volts x amps) for all of the secondary windings. 
   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:       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.
