Resistor 0.25W 9.1M Ohm (10 pcs)

The Resistor 0.25W 9.1M Ohm is a through-hole fixed resistor with a resistance of 9.1 MΩ and a power rating of 0.25 W, sold in a pack of 10. It is a standard E24 value just below 10 MΩ, used when a circuit needs a very high resistance that draws almost no current, for example in low-drain voltage dividers, long RC delays and bias networks for high-impedance inputs.

Resistor 0.25W 9.1M Ohm Applications

• High-impedance voltage dividers that barely load a battery or signal
• Long RC delays: 9.1 MΩ × 1 µF ≈ 9.1 s

• Bleeder resistors across high-voltage capacitors
• Capacitive touch and proximity sensors

What's in the Box

• 10 × 9.1 MΩ 0.25 W resistors

Tip: When a megaohm voltage divider feeds an Arduino or ESP32 analog input, add a 100 nF capacitor from the ADC pin to GND. The ADC needs a low source impedance while it samples, and the capacitor supplies that charge so the readings stay stable.

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