TTCM4-4+

Product Overview

TTCM4-4+ is a Mini-Circuits 1:4 core-and-wire RF balun transformer specified for 0.5 MHz to 400 MHz. The 1:4 ratio provides a substantial impedance step while the published amplitude and phase balance support push-pull circuitry.

Its low-frequency extension and 400 MHz upper limit cover IF, HF, VHF and lower-UHF applications. This standard package version uses a plastic base with solder-plated leads and should be distinguished from the TTCM4-4X+ flat-lead variant.

Quality & Sourcing

Antrex Electronics can support sourcing of TTCM4-4+ for production, repair and shortage requirements. Incoming inspection should compare the exact ordering code, operating band, impedance relationship, package or connector configuration and any center-tap or suffix-specific mechanical details. Parts from the same transformer family may not be interchangeable when the ratio, port impedance, lead style or installed geometry changes.
