SRD-12VDC-SL-C

The Songle SRD-12VDC-SL-C is a PCB-mounted electromechanical relay with a 12V DC coil and a Single Pole Double Throw (SPDT / 1 Form C) contact configuration. The SRD series is available with 7A, 10A, and 15A contact ratings. For the 10A version, the contacts are rated for 10A at 250VAC. The 12V coil has a typical power consumption of 0.36W, corresponding to a coil current of approximately 30mA and a coil resistance of approximately 400Ω at 20°C.

The SRD-12VDC-SL-C uses a 12V DC coil with a typical power consumption of 0.36W. At the rated voltage, the coil current is approximately 30mA, and the coil resistance is approximately 400Ω at 20°C, as specified in the datasheet.

According to the SRD series datasheet, the relay has a mechanical life of 1 × 10⁷ operations. The specified electrical life is 1 × 10⁵ operations or 1 × 10⁴ operations, depending on the applicable contact load and test conditions defined by the manufacturer. Refer to the product specifications for the appropriate rating for your application.

The SRD-12VDC-SL-C is designed for PCB mounting, and the manufacturer provides the recommended PCB footprint and mounting dimensions in the datasheet. When switching mains or other high-voltage circuits, PCB layout should follow the applicable electrical safety standards for creepage, clearance, and conductor sizing appropriate to the target application.

According to the SRD series datasheet, the relay is available with operating temperature ratings of −40°C to +85°C or −40°C to +105°C, depending on the version. The specified operating humidity is up to 85% RH at 20°C. These ratings should be considered when selecting the relay for the intended operating environment.
