JY25H-K-505 – FUJITSU

The JY25H-K-505 is a single-pole, single-throw (SPST) normally open (N.O.) electromechanical power relay manufactured by Fujitsu. It is designed for printed circuit board (PCB) mounting and switching applications requiring a contact rating of up to 5A at a specified voltage, which should be verified against the manufacturer’s datasheet. This relay utilizes an electromagnetic coil to actuate the switching mechanism, providing electrical isolation between the control circuit and the load. The coil voltage and resistance are critical parameters for proper operation and must be considered during circuit design. The device’s compact form factor is suitable for applications where board space is limited. Reliability data, including expected mechanical and electrical life cycles, and safety certifications (e.g., UL, CSA, VDE) are essential for ensuring suitability in the intended application and should be obtained from the official datasheet.
