Resistor 0.25W 10M Ohm (10 pcs)

The Resistor 0.25W 10M Ohm is a through-hole fixed resistor with a very high resistance of 10 MΩ and a power rating of 0.25 W, sold in a pack of 10. At 5 V it lets only 0.5 µA flow, which makes it useful wherever a circuit must draw almost no current: capacitive touch sensors, high-impedance inputs, bleeder resistors and long RC time constants.

Resistor 0.25W 10M Ohm Applications

• Capacitive touch and proximity sensing with the Arduino CapacitiveSensor library
• Bleeder resistors that slowly discharge high-voltage capacitors
• Bias resistors for high-impedance op-amp, JFET and CMOS inputs

• Feedback resistor in CMOS crystal oscillator circuits

What's in the Box

• 10 × 10 MΩ 0.25 W resistors

Tip: Do not hold both leads with your fingers when measuring. Your skin resistance is in the megaohm range and sits in parallel with the resistor, so the multimeter reads low; clip the resistor or lay it on the table instead.

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