# CPDT-12V (Component) ## Description The CPDT-12V is an electromechanical relay designed for switching and control applications in industrial, automotive, consumer, and embedded electronic systems. Operating from a nominal twelve-volt coil supply, this relay provides reliable isolation between low-power control circuitry and higher-power loads. Its compact construction, robust contact mechanism, and dependable switching performance make it suitable for power distribution, automation controls, battery-powered equipment, protection circuits, and general-purpose switching applications. The relay incorporates a magnetic coil and mechanical contact assembly that enables safe control of AC or DC loads while maintaining electrical isolation between the control and load sides. Its durable design supports repeated switching operations and long service life in demanding environments. Features Electromechanical relay with nominal twelve-volt coil operation Provides galvanic isolation between control and load circuits Suitable for AC and DC load switching Reliable contact performance for power and signal applications Compact package for PCB mounting Low control power requirement Durable contact system for long operational life Fast switching response characteristics Compatible with industrial and embedded control systems Designed for automation, protection, and power management circuits Applications Industrial automation equipment Power control modules Battery-powered systems Automotive electronics Home appliance control circuits Smart energy management devices Security and alarm systems Embedded controller interfaces Motor and actuator switching General-purpose load control applications Electrical Characteristics Nominal coil voltage: twelve volts DC Electromagnetic actuation mechanism Isolated contact structure Designed for low-voltage control interfaces Supports switching of resistive and inductive loads Stable operation across specified environmental conditions Mechanical Characteristics PCB-mount relay construction Compact footprint for space-constrained designs Durable housing for electrical and mechanical protection Secure terminal arrangement for reliable soldering and connection Engineered for repeated switching cycles Environmental Characteristics Suitable for indoor industrial and commercial environments Resistant to normal operating vibration and mechanical shock conditions Designed for reliable operation across standard electronic equipment temperature ranges #commonpartslibrary #relay #electromechanicalrelay #switchingdevice #powermanagement #industrialautomation #controlsystems #pcbmount #automationelectronics #circuitprotection #embeddedsystems #industrialelectronics ## Component Details - **Owner:** lcsc - **Created:** 10/31/2024 - **Last Updated:** 6/1/2026 - **Visibility:** Public - **Package or Case Code:** SOT-23-3_L2.9-W1.3-P1.90-LS2.4-BR - **Part Type:** TVS - **JLCPCB Part Class:** Extended Part - **Manufacturer Name:** Comchip(典琦) - **LCSC Part Number:** C2443367 - **Manufacturer Part Number:** CPDT-12V - **Datasheet URL:** https://www.mouser.com/datasheet/3/819/1/CPDT_12V_RevB364124.pdf - **Used in:** 55 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
