Description
The JQC-3F is a general-purpose electromagnetic PCB relay (single pole changeover / SPDT) commonly offered in coil voltages from 3V to 24V DC. It supports load switching up to around 10A at 250VAC or 30VDC with silver alloy contacts in a compact footprint. This relay is used wherever isolation between control logic and power circuits is needed and space is limited.
