Resistor 0.5W 1M ohm (5 pcs)

The Resistor 0.5W 1M ohm is a through-hole fixed resistor with a resistance of 1 MΩ and a power rating of 0.5 W, sold in a pack of 5. High values like 1 MΩ draw very little current, so they are used for weak pull-downs, high-impedance voltage dividers, long RC time constants and bias networks where low power matters.

Resistor 0.5W 1M ohm Specifications

• Resistance: 1 MΩ (1,000,000 ohms)
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 1M ohm Applications

• Capacitive touch sensing with the Arduino CapacitiveSensor library
• RC timing: 1 MΩ with 1 µF gives a time constant of about 1 second
• Weak pull-down resistors on high-impedance inputs
• Bias and feedback resistors in op-amp and CMOS oscillator circuits
• Bleeder resistors that slowly discharge capacitors

What's in the Box

• 5 × 1 MΩ 0.5 W resistors

Tip: When you measure a 1 MΩ resistor with a multimeter, do not hold both leads with your fingers: your body resistance is added in parallel and the reading drops. At 5 V a 1 MΩ resistor passes only 5 µA.

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