상품 특징

• Specs & key features: OE#JS1-12V-F power relay with 12VDC coil (30 mA, 400 ohm, 360 mW), non-latching. Contact form: SPDT / 1 Form C (includes NO, NC and COM terminals) for switching a load from a control signal; resistive rating up to 10A 250VAC (NO), 6A 277VAC, and 5A 30VDC; max switching voltage 250VAC / 100VDC. 5-pin PC terminals, sealed construction, through-hole PCB mount, miniature cubic body with universal terminal footprint; AgSnO2 contacts for stable switching. Related series code: JS1F-12V-F (flux-resistant type)-confirm exact suffix/footprint. Replacement relay for boards originally using JS1-12V-F-confirm OE#, footprint, and contact form before ordering.
• Install/replace tips: This is a through-hole PCB relay (PC pins), typically soldered directly onto a printed circuit board inside a control module/device. Before service, disconnect power (and disconnect the battery for 12V systems). Record the relay's orientation from the board's silkscreen, then desolder the old relay, clean plated holes, and solder the new relay with proper wetting and no bridges. Verify the coil drive is 12VDC, and verify terminal functions (NO/NC/COM) match your circuit. Keep the load within the relay's DC rating and inspect for heat damage on traces/connectors during reassembly.
• Compatible with 12V DC control boards that specify OE#JS1-12V-F PCB Relay — for circuit-board relay replacement/repair where the board marking calls out JS1-12V-F and the footprint matches (SPDT / 1 Form C, 5-pin through-hole). Not a plug-in blade relay for a fuse/relay box; it is designed to be soldered onto a PCB. Common equipment categories using this relay style include control boards in appliances, office machines, and vending equipment; applications vary by device. No verified year/make/model vehicle fitment list exists for this component code, so confirm fitment by OE#, board marking, and footprint before ordering.
• Compatible with troubleshooting for relay-related faults: failed load switching (device won't power a fan/pump/valve/solenoid), intermittent operation, stuck-on load, or a relay that does not actuate when the control signal is applied. If the original relay shows heat discoloration, burnt odor, or contact pitting, replacing the relay may help-but also check upstream fuses, wiring, connectors, and the board's driver stage. Quick bench checks: verify coil is for 12VDC, measure coil resistance (~400 ohm nominal), apply 12V to the coil to confirm actuation, and verify COM<->NO/NC continuity changes with a multimeter. After replacement, function-test under normal load.
• Compatible with board-repair toolkits and common companion parts: desoldering braid or pump, no-clean flux, solder, tip-tinner, and cleaning steps after power is removed. If the failure was caused by over-current or arcing, inspect and replace any damaged connectors, cracked solder joints, carbonized PCB areas, and protective components on the same circuit (such as fuses or suppression parts) according to your device manual.

Keeping a spare relay on hand is helpful for periodic service and troubleshooting on control boards.
• Compatible with careful pre-purchase verification: match OE#JS1-12V-F, confirm the relay is 1 Form C (SPDT) and that your board uses the NC pin (terminal 4) if required. Verify coil voltage is 12VDC and confirm the contact rating meets your load type (AC vs DC). If your original part has a different suffix or footprint, do not substitute blindly-use your device manual or board markings to confirm. After soldering, keep the relay clean and dry; avoid harsh cleaning methods (e.g., ultrasonic cleaning) that can stress components.
