The HF115F/012-1H1BF(257) is a miniature high-power relay designed for PCB mounting. It operates with a 12VDC nominal coil voltage and features a 1 Form A (SPST-NO) configuration with AgNi contacts, capable of switching up to 12A at 250VAC. This relay is characterized by its low profile height of 15.7 mm, a high dielectric strength of 5000VAC between the coil and contacts, and a 10mm creepage distance. With its Class F insulation system and reinforced insulation meeting VDE standards, it is well-suited for applications requiring high reliability and safety, such as in home appliances and industrial control systems.
