Balun Transformers / Wideband Transformers for Digital TV Tuners, WBL Series (TCPWCH-2012BL)

A balun is a type of transformer. Balun transformer is a device which one pair of terminals is balanced, the currents are equal in magnitude and opposite in directions, such as a twisted pair cable. The other pair of terminals is unbalanced; one side is connected to electrical ground and the other carries the signal, such as a coaxial cable.

DeMint (TCPWCH-2012BL) has commercialized chip transformers (balun transformers), which are used to convert between unbalanced-balanced signals in the antenna inputs of TV tuner circuits for terrestrial digital broadcast compatible compact mobile devices.

By taking advantage of the advanced winding technology which using paired or/and triple wires enabling high uniformity, DeMint balun transformers for TV tuners have been made by winding wire around a fine ferrite core, and are widely used in large-scale devices such as TVs and desktop PCs.

SMD Balun/Wideband Transformers can be used between various parts of a wireless or cable communications system. Balun transformers (TCPWCH-2012BL) provide port impedance with 50 Ω or 75 Ω to match coaxial cables which have characteristic impedances of 50 Ω or 75 Ω. The supported frequencies cover the 45 MHz to 870 MHz range that includes the full terrestrial broadcasting band, and other 50 MHz ~ 1200 MHz, 1000 MHz ~ 1500 MHz, 950 MHz ~ 2150 MHz, and 400 MHz ~ 1800 MHz range to cover a wide variety of applications.

All (TCPWCH-2012BL) series comes a wide variety of options to meet your needs with halogen free and RoHS Directive. DeMint is able to customize and manufacture your request, with comprehensive application engineering and design support available for customers worldwide.
