The W172DIP-3 is an SPDT (1 Form C) reed relay designed for economy and quality in a standard dual in-line package. It operates on a nominal coil voltage of 12V DC with a coil resistance of 500 ohms, consuming 288mW of power. This relay can switch up to 0.2A at a maximum of 100VDC and provides high isolation with a dielectric strength of 1500VDC between the coil and contacts. Its industry-standard pin spacing and suitability for high-density board mounting make it ideal for telecom, security, and other general-purpose applications.
