Resistor 0.25W 820K ohm (10 pcs)

The Resistor 0.25W 820K ohm is a through-hole fixed resistor with a resistance of 820 kΩ and a power rating of 0.25 W, sold in a pack of 10. It is well suited to ADC voltage dividers in battery-powered projects, RC timing networks and gain-setting in op-amp circuits, where a high resistance keeps current low.

Resistor 0.25W 820K ohm Applications

• High-impedance voltage dividers for reading battery voltage on an Arduino or ESP32 ADC
• Timing resistors in 555 timer and RC delay circuits
• Gain-setting and feedback resistors in op-amp circuits
• Biasing high-impedance inputs such as CMOS and JFET stages
• Electronics education and prototyping

What's in the Box

• 10 × 820 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. In a battery divider for an ESP32 or Arduino, add a 100 nF capacitor from the ADC pin to ground; a high-value divider has a high source impedance and the capacitor keeps readings stable.
