Resistor 0.5W 8.2M ohm (5 pcs)

The Resistor 0.5W 8.2M ohm is a high-value through-hole resistor rated at 0.5 W, supplied in a pack of 5. With 8.2 MΩ of resistance it passes well under a microamp at 5 V, which makes it a good choice for sensitive, high-impedance circuits where a lower value would load the signal.

What's in the Box

• 5 × 8.2 MΩ 0.5 W resistors

Tip: In the Arduino CapacitiveSensor library, a larger resistor makes the sensor more sensitive and lets it detect a hand from further away, but it also responds more slowly. Start with this value and adjust to suit your sensor plate.

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