Resistor 0.5W 5.1M ohm (5 pcs)

The Resistor 0.5W 5.1M ohm is a through-hole fixed resistor with a very high resistance of 5.1 MΩ and a power rating of 0.5 W, sold in a pack of 5. Values in the megaohm range let only a tiny current flow, so they are used where a circuit must load a signal as little as possible, such as touch sensors, high-impedance inputs and long RC time delays.

Resistor 0.5W 5.1M ohm Specifications

• Resistance: 5.1 MΩ (5,100,000 ohms)
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Current at 5 V: about 1 µA
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 5.1M ohm Applications

• Capacitive touch and proximity sensing with the Arduino CapacitiveSensor library
• Long RC time delays: 5.1 MΩ with 1 µF gives a time constant of about 5 seconds
• High-impedance bias and input resistors for op-amp and FET circuits
• Very low-current pull-down resistors
• Electronics education and prototyping

What's in the Box

• 5 × 5.1 MΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. When you measure a 5.1 MΩ resistor with a multimeter, do not hold both leads with your fingers, because your body resistance in parallel will make the reading too low.
