Frequently Asked Questions
What coil voltage and power does the JS1A-12V-F require for reliable operation?
The JS1A-12V-F requires a 12 V DC coil voltage with an operate voltage of 8.4 V and a release voltage of 1.2 V. The coil consumes 360 mW at the nominal 12 V supply, drawing a maximum of 30 mA, which is within the drive capability of most relay driver transistors or dedicated relay driver ICs.
What are the physical dimensions of the JS1A-12V-F and how does it mount on a PCB?
The JS1A-12V-F measures 22 mm in length, 16 mm in breadth, and 16.4 mm in height. It uses a through-hole PCB-mount footprint, making it compatible with standard wave-soldering or hand-soldering assembly processes used in industrial control boards and home-appliance designs.
In which industrial or home-appliance control systems is the JS1A-12V-F commonly deployed?
The JS1A-12V-F is commonly used in HVAC thermostats, washing-machine control boards, industrial relay panels, and lighting control modules where a 12 V coil relay must switch mains-level AC loads. Its 400 Ω coil resistance and 360 mW power draw also make it suitable for battery-backed UPS bypass switching and energy management systems.
Is the JS1A-12V-F a lead-free, RoHS-compliant part?
Yes, the JS1A-12V-F carries a Pb-free code of Yes and is fully RoHS compliant. This means it is manufactured without restricted hazardous substances and can be assembled using standard lead-free SAC305 solder at peak reflow temperatures around 260°C, satisfying EU RoHS Directive requirements for global distribution.
