Resistor 0.25W 5.1K ohm (10 pcs)

The Resistor 0.25W 5.1K ohm is a through-hole fixed resistor with a resistance of 5.1 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. It is well known as the pull-down resistor on the CC pins of a USB Type-C socket, which lets a USB-C charger detect the device and supply 5 V. It is also used for pull-ups, voltage dividers and bias networks in Arduino and ESP32 projects.

Resistor 0.25W 5.1K ohm Applications

• CC pull-down resistors for USB Type-C 5 V power inputs
• Pull-up and pull-down resistors for buttons and logic inputs
• Voltage dividers for analog inputs
• Transistor biasing

What's in the Box

• 10 × 5.1 kΩ 0.25 W resistors

Tip: When adding a USB-C socket to a project, fit one 5.1 kΩ resistor from CC1 to ground and another from CC2 to ground; without them many USB-C chargers will not supply power. With 5.1 kΩ, the 0.25 W limit is reached at about 36 V across the resistor.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
