The HF326 is a high-performance signal relay from the Axicom HF3 series, designed for reliable printed circuit board mounting. Featuring a PCB-SMT terminal type, this relay offers seamless integration. With low insertion loss of -0.03 dB at 100 MHz, -0.12 dB at 900 MHz, and -0.4 dB at 3 GHz, it ensures efficient signal transmission. The 1 Form C (CO) contact configuration and a maximum switching voltage of 220 VDC or 250 VAC make it suitable for versatile applications. With a coil resistance of 2057 Ω and operating at 12 VAC, the HF326 guarantees robust performance. It provides excellent isolation of -72 dB at 900 MHz, -80 dB at 100 MHz, and -40 dB at 3 GHz, along with a contact current rating of 2 A. Compact in size at 14.6 x 7.2 x 9.1 mm, this RoHS-compliant relay is ideal for use in HVAC systems and other high-reliability applications.
