The 109RF50-1-A-5/2D is a Pickering Electronics Series 109 Micro-SIL® RF reed relay designed for high-density PCB applications requiring low-level signal switching and excellent RF performance. It features a 50 Ω coaxial configuration, SPST normally open (1 Form A) contact arrangement, and a 5 VDC coil with an integrated diode for coil suppression. The relay uses a mu-metal magnetic shield package to minimize magnetic interaction when multiple relays are closely stacked, making it suitable for compact test systems, RF switching matrices, and high-speed signal applications.
