상품 특징

• Specs: 12V DC coil, SPST-NO (1 Form A) contact, non-latching power relay; max contact current 40A; switched voltage up to 28VDC / 277VAC (rating depends on load). Operate time 15ms, release time 10ms; electrical life 100,000 ops; mechanical life 10,000,000 ops. Dielectric strength up to 4kV (coil-to-contact). Operating temp (DC coil): -55°C to +85°C. Through-hole PC pin (THT/PCB mount), body approx. 32.3 x 27.1 x 20 mm. OE/Part No.: HF105F-1-012DT-1HST; also listed as HF105F-1/012DT-1HSTF by some distributors—match your original relay marking/footprint. Note: avoid long-term continuous load at the max rating.
• Install/Replace Tips: Disconnect battery power first. Confirm your circuit requires a 12V DC coil (min operating about 9V DC per datasheet listings) and an SPST-NO contact. This is a solder-in, through-hole PCB relay (PC pin terminals); match your board footprint and terminal count—some HF105F-1 footprints include an extra stability terminal (#6). Use proper desoldering tools to avoid lifting pads. After replacement, test by applying 12V to the coil (per your service manual) and verifying the load contacts close; inspect for cold solder joints and heat damage around the pads.
• Fitment Notice: Vehicle year/make/model fitment is not reliably published for this relay marking, so we do not list specific vehicles. Confirm fitment by the printed OE/Part No. HF105F-1-012DT-1HST, coil voltage (12V DC), contact form (SPST-NO), and the PCB footprint on your unit using your vehicle/module service manual. If the markings or pin layout do not match, do not install.
• Typical Applications (circuit dependent): electromagnetic power relay used for high-current switching on relay boards/power distribution modules, such as radiator fan, blower motor, fuel pump, lighting, or other 12V loads. Choose based on your wiring diagram and current draw; use within rated limits, ensure good heat dissipation, and keep proper fuse protection as required by the vehicle.
