TC1 SMD Audio & Signal RF Transformers

Mini-Circuits TC1 SMD Audio and Signal RF Transformers span a 0.15MHz to 4000MHz frequency range with either a 50Ω, 75Ω, or 100Ω impedance. These single-channel transformers feature a 1Ω to 16Ω typical secondary impedance ratio, a 0.1dB to 3.0dB typical insertion loss range, and a 12dB to 30dB typical return loss. Options include 0.25W or 0.5W RF power and 30mA, 100mA, or 200mA DC currents.
