U Series Reed Relay

The U Series is an ultraminiature, high-frequency reed relay designed for advanced RF switching in space-constrained PCB layouts. With a compact surface-mount footprint and J-Lead packaging, the U Series delivers exceptional RF performance up to 8 GHz, making it ideal for automated test equipment (ATE), telecommunications, and wireless communication systems.

Engineered to balance miniature size with high-frequency capability, the U Series supports SPST-NO (Form A) contact configuration and coil voltages of 3.3 VDC and 5 VDC. Rated for up to 3 W, 100 VDC, and 0.2 A, it offers low insertion loss and reliable signal integrity in high-density assemblies.
