Resistor 0.25W 680K 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
• Bleeder resistors across small filter capacitors
• Timing resistors in 555 timer and RC delay circuits
• Electronics education and prototyping

What's in the Box

• 10 × 680 kΩ 0.25 W resistors

Tip: 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. Resistors have no polarity, so they can be fitted either way round.
