Datasheet Summary
Powered by GS/AI

The 7-1904118-1 is a latching automotive PCB relay with a bistable two-coil system, designed for high-endurance applications up to 125°C. It features a single form A, normally open contact with silver alloy contacts, rated for 12VDC coil operation and a limiting continuous current of 60A at 23°C, reducing to 45A at 85°C. The relay supports a maximum switching current of 200A and maintains switching state integrity during battery voltage breakdown. It is solderable via THT (through-hole) technology, with an overall dimensions of 18.3mm length, 16mm width, and 15.9mm height, weighing approximately 11g. The relay meets IEC 61810-1 and is EU RoHS/ELV compliant, rated for functional vibration resistance up to 20g and shock resistance up to 100g in set position. Ambient temperature range is -40°C to +125°C, with an environmental protection classification of RT III. Initial dielectric strength is 500VACrms between contacts and between contact and coil.
