T4-1-KK81+ 詳細描述
Product Overview
T4-1-KK81+ delivers the T4-1 family’s 1:4 transformation from 200 kHz to 350 MHz in the KK81 package. It is designed for broadband 50 Ω circuits that need to feed a higher-impedance balanced load, or to recover a single-ended signal from a differential stage with the same ratio.
The 250 mW RF limit and 30 mA DC-current rating define the usable operating envelope. Because the KK81 package differs from the W38 and plug-in versions, this ordering code is particularly relevant for repair and production BOMs where the existing pad geometry and component height are fixed.
