SMD RF Balun Transformers (TCB4F)
Direct Electronics has introduced SMD Common Mode RF Transformers (RF Balun Transformers) in 3.8 x 4.4 mm compact size, which are used to convert between unbalanced-balanced signals in the antenna inputs of tuner circuits for terrestrial digital broadcast compatible compact devices. Up to now baluns have been made by winding wire around a spectacle-shaped ferrite core, and are widely used in electronic devices such as TVs and desktop PCs.
Direct SMD common mode (TCB4F) Baluns are primarily designed for choking power lines and conform to the RoHS compliant and Lead-free. SMD (TCB4F) can be customed designs and tighter tolerances available on request.
Windings use paired or and triple wires for high uniformity. 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. Application of SMD choke coils specific designs also available including different inductance values and Q specifications adjusted to frequency requirements.
Direct is equipped to design and produce standard and custom Balun components to meet many design and reliability demands. Custom parts are available on request. Direct will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
