상품 특징

• Specs: 12VDC coil power relay, SPST-NO (1 Form A), monostable/non-latching; 10A contact rating; 4-pin through-hole PCB (solder pin) termination. Electrical refs: 320Ω coil resistance, 450mW coil power rating, switching up to 30VDC / 250VAC (use within your circuit design limits). OE/Part ID: T77V1D10-12 (also seen as T77-V1D1012 / 1-1393194-9). Use for repairing/replacing a failed relay on a control board when the original markings/specs match.
• Install/replace tips: Disconnect vehicle battery / power supply before service. This is a PCB through-hole relay—desolder the old relay, clean pads, and solder the new relay fully seated. Confirm pin layout and PCB footprint (4 pins, SPST-NO) to avoid mis-wiring. Common location: inside an electronic control module or relay/control board (not a plug-in fuse-box relay). After install, inspect solder joints and verify coil is 12VDC before energizing.
• Fitment: This relay is identified by the OE/part number on the original component (T77V1D10-12). Because vehicles and modules can use different relay footprints and contact forms, confirm fitment by: (1) OE/marking match, (2) coil voltage 12VDC, (3) SPST-NO contact form, (4) 4-pin PCB footprint, and (5) current rating required by your circuit. If any of these do not match, do not install.
• Related maintenance: A relay failure can be caused by overheated solder joints, damaged PCB traces, or upstream fuses/connectors. When replacing the relay, also check the mating circuit (pads, traces, connectors, and the load) for heat discoloration or looseness. Keeping a spare relay for the same board can reduce downtime for future electrical troubleshooting.
