N40782C5V0.2W (N40782C5V0.2W) Relay — compact, lowpower DPDT switching solution, pack of 5 Key benefits Low coil power (0.2 W) minimizes energy consumption and heat, making these relays suitable for batterypowered and lowpower control systems. 5 V DC coil voltage is compatible with common microcontrollers and logiclevel drivers for direct control from Arduino, Raspberry Pi (with appropriate driver), and other 5 V control circuits. Two changeover contacts (2C / DPDT) provide flexible signal routing and dualcircuit switching within a single compact device. Rated for up to 30 VDC and 2 A per contact for reliable switching of small DC loads. Key attributes Model: N40782C5V0.2W (also listed as N40782C5V0.2W) Coil voltage: DC 5 V Coil power: 0.2 W Contact configuration: 2C (two Form C / DPDT) Contact rating: 30 V DC, 2 A Pin count: 8 pins for PCB or throughhole mounting Package: 5 pieces per (5PCS) Why customers choose this relay Energy efficient: 0.2 W coil power reduces draw from the control supply and helps keep overall system power low. Compact and versatile: DPDT contact arrangement lets you control two separate circuits or switch polarity/paths without adding multiple relays. Easy to integrate: 5 V coil voltage is a standard for many electronic control systems, simplifying driver circuit design. Clear DC switching limits: specified 30 VDC and 2 A contact rating helps you match the relay to appropriate loads and avoid overloading. Installation and performance notes The relay uses an 8‑pin footprint common to DPDT relays for simple PCB layout or throughhole mounting. Verify pin orientation and footprint before soldering. Coil current approximately 40 mA (0.2 W / 5 V). Use a suitable driver transistor or MOSFET if controlling directly from a microcontroller pin is not recommended; a driver or transistor with a flyback diode is advised to protect control electronics. Designed for switching DC loads up to the specified rating; do not exceed 30 VDC or 2 A per contact. Typical applications / use cases Microcontroller control: Use with Arduino or other 5 V control boards to switch small DC motors, solenoids, or lighting circuits within the 30 VDC/2 A limit. Signal routing and testing: Ideal for test fixtures, audio signal switching, or routing lowvoltage DC signals where DPDT switching is needed. Portable and batterypowered devices: Low coil power makes these relays suitable for batteryoperated systems that require reliable switching with minimal energy impact. What's in the box Five (5) units of N40782C5V0.2W / N40782C5V0.2W relays (8 pins each). Safety and selection reminder Confirm load current and voltage do not exceed the relay's 30 VDC, 2 A rating. Provide correct drive circuitry and suppression (flyback diode or snubber) for inductive loads to protect the relay and driver. Check PCB footprint and pinout against your design before assembly. This product delivers a compact, lowpower DPDT relay solution for reliable DC switching in small electronics, control panels, and test equipment.
