Panasonic Through Hole High Frequency Relay 12V DC Coil 200mW Power SPDT Contact Configuration ARS1112

Panasonic ARS1112 is a through hole high frequency relay designed for switching high-frequency signals up to 3 GHz. It operates with a 12V DC coil voltage delivering 200mW coil power in a compact super miniature form factor measuring 14mm by 7.2mm enabling space-efficient circuit designs.

This relay features a single pole double throw (SPDT) contact configuration with gold plated contacts providing reliable electrical connections with low contact resistance of 100mΩ. The relay exhibits superior high frequency characteristics including insertion loss of just 0.3 dB and isolation of 30 dB, making it ideal for broadcast, video, mobile phone base stations, measurement, and communication applications requiring minimal signal degradation.

With a coil resistance of 720Ω and a voltage standing wave ratio (VSWR) of 1.4 at 3 GHz, the ARS1112 ensures efficient coil operation and reduced signal reflections. Its wide operating temperature range from -40°C to 70°C makes it suitable for harsh industrial and outdoor environments.

Panasonic manufactures this relay in Japan, assuring quality and long-term reliability. The through hole mount type facilitates easy PCB integration with stable mounting suited for industrial automation, telecommunications, and RF signal switching use cases.
