Balun Transformers (TCB5FL)

A Balun is a device which converts balanced impedance to unbalanced and vice versa. In addition, baluns can also provide impedance transformation, hence the name Balun Transformers.

Direct utilizes the latest winding technology using paired wires for high uniformity and enabling the most cost-effective designs in manufacturing surface mount baluns.

Direct (TCB5FL) baluns are primarily designed for choking power lines and conform to the RoHS compliant and Lead-free. SMD (TCB5FL) feature with ultra-compact size, wide inductance selection, and low-resistance coils. SMD (TCB5FL) can be customed designs and tighter tolerances available on request.

Application of RF balun transformer specific designs also available including different inductance values and Q specifications adjusted to frequency requirements. Base pins are end proccessed to allow direct mounting on PCB. Ideal for use in double balanced mixers, and as broad band transformers, transistors and for impedance conversion.

Direct will also produce devices outside these specifications to meet customer requirements, with comprehensive application engineering and design support available for customers worldwide.
