The NDMB132100 is a multi-channel RF transformer module designed for high-frequency signal conditioning and isolation in communication systems. It features four differential transformer pairs with a 1:1±3% turn ratio, integrated 22 nF capacitive filtering on each channel, and a 1000 pF 2 kV capacitor on the shield for EMI suppression. The module operates across a frequency range of 1 to 500 MHz with insertion loss specifications of -2.0 dB maximum at 1–400 MHz and -3.0 dB maximum at 400–500 MHz, achieving return loss of -22 dB minimum at 1–100 MHz. With a current rating of 960 mA per differential pair, 1500 VAC isolation capability, and a stainless steel shielded housing with gold-plated mating contacts, the NDMB132100 is well-suited for high-speed data transmission, RF signal distribution, and isolation applications in telecommunications and instrumentation equipment.
