Resistor 0.25W 510K ohm (10 pcs)

The Resistor 0.25W 510K ohm is a through-hole fixed resistor with a resistance of 510 kΩ and a power rating of 0.25 W, sold in a pack of 10. Use it for voltage sensing, setting gain in op-amp stages and pulling high-impedance inputs to a defined level without wasting current.

Resistor 0.25W 510K ohm Applications

• High-impedance voltage dividers for reading battery voltage on an Arduino or ESP32 ADC
• Gain-setting and feedback resistors in op-amp circuits
• Biasing high-impedance inputs such as CMOS and JFET stages
• Bleeder resistors across small filter capacitors
• Electronics education and prototyping

What's in the Box

• 10 × 510 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. When checking it with a multimeter, do not hold both leads with your fingers, because your body resistance in parallel makes the reading lower than 510 kΩ.
