T4-1-X65+ — Overview
T4-1-X65+ by Mini-Circuits is a component in the RF Transformer (1:4 impedance ratio, 0.2-350 MHz, plug-in) category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The T4-1-X65+ is a 1:4 (secondary/primary) core-and-wire RF transformer covering 0.2 to 350 MHz with 0.6 dB typical mid-band insertion loss and a center-tapped secondary. It is rated for 0.25 W RF and 30 mA DC and is supplied in the X65 plug-in case with six through-hole pins. The "X65" designator is simply the Mini-Circuits case style (plug-in leads); the "+" suffix indicates RoHS compliance, not an electrical variant.
