Resistor 0.5W 9.1M ohm (5 pcs)

The Resistor 0.5W 9.1M ohm is a through-hole fixed resistor with a very high resistance of 9.1 MΩ and a power rating of 0.5 W, sold in a pack of 5. Only a tiny current flows through it, so it suits high-impedance circuits such as capacitive touch sensors, measurement inputs and long RC time constants.

Resistor 0.5W 9.1M ohm Specifications

• Resistance: 9.1 MΩ (9,100,000 ohms), a standard E24 value
• Power rating: 0.5 W (1/2 W)
• Current at 5 V: about 0.55 µA
• RC time constant with 1 µF: about 9.1 s (τ = R × C)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 9.1M ohm Applications

• Capacitive touch and proximity sensors with the Arduino CapacitiveSensor library
• Feedback resistors in photodiode and op-amp amplifier circuits
• High-impedance input and voltage divider resistors for measurement circuits
• Long delays in RC and 555 timer circuits

What's in the Box

• 5 × 9.1 MΩ 0.5 W resistors

Tip: Most digital multimeters have an input resistance of about 10 MΩ, close to this resistor's value, so measuring the voltage across it loads the circuit and gives a reading that is too low.

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