상품 특징

• Specs: 5VDC coil, 4-pin 1 Form A / SPST-NO contact ("M"), flux-tight "SS" case; contact material silver alloy; contact resistance 100mΩ max; operate/release time 10ms/5ms max; switching ratings per Y3U series: up to 20A @125VAC, 17A @250/277VAC, 17A @30VDC (rating varies by contact form/load—match your exact marking). Outline approx 21.2×16×21.8mm, unit weight ~11g. Part No. (OE#): Y3U-SS-105LMF (F = glow-wire material option).
• Install/replace tips: This is a through-hole PCB power relay (not a plug-in blade relay). Disconnect power, discharge capacitors, and verify the PCB footprint/pin map (bottom-view wiring diagram in datasheet). Desolder the old relay, clean pads, insert the new relay fully seated, and solder with solid wetting to avoid cold joints. Before reassembly, bench-test: apply the correct coil voltage (5VDC) and check NO contact continuity change. Typical locations: main control boards in home appliances (A/C, heater, air fryer), office equipment, vending machines, and certain automotive accessory control modules (window/antenna/door lock controllers).
• Compatible with 5V Home Appliances Control Board PCB Relay; Compatible with 5V Air Conditioner Mainboard PCB Power Relay; Compatible with 5V Heater Control PCB Switching Relay; Compatible with 5V Air Fryer Control Board PCB Relay; Compatible with 5V Vending Machine Control PCB Relay; Compatible with 5V Office Equipment Main Board PCB Relay; Confirm fitment by matching OE#Y3U-SS-105LMF, coil voltage, and PCB layout before ordering.
• Compatible with 5V Automotive Electric Window Control Module PCB Relay; Compatible with 5V Automotive Antenna Control Module PCB Relay; Compatible with 5V Door Lock Control Module PCB Relay; Compatible with 5V Body Electronics Control Board PCB Relay; Compatible with 5V Auxiliary Controller Mainboard Relay; If you’re unsure, confirm fitment by OE number, board silkscreen, and the relay’s contact form (NO/NC/CO) before purchase.
• Compatible with Y3U Series SS-type Flux-Tight Power Relay Footprint (21.2×16×21.8mm) Relay; Related/alternate coil-voltage variants in the same family (verify your marking): Y3U-SS-112LM (12V coil), Y3U-SS-124LM (24V coil), and other 3/6/9/15/18/36/48V options. Complementary spares: keep a matching coil-voltage relay for the same control box/PCB to reduce downtime. Do not mix coil voltages—using the wrong coil can cause non-operation or overheating.
• Symptoms a failing relay can cause (application-dependent): intermittent power to a load, device won’t start, clicking without switching, or stuck contacts. This relay is designed for resistive-load switching per datasheet ratings—always follow your equipment’s service manual and circuit design.
