Resistor 0.5W 4.3M ohm (5 pcs)

The Resistor 0.5W 4.3M ohm is a through-hole fixed resistor with a resistance of 4.3 MΩ and a power rating of 0.5 W, sold in a pack of 5. 4.3 MΩ is an E24 series value, and at 5 V it passes only about 1.2 µA, which makes it suited to long RC time constants, high-impedance inputs and voltage dividers that must not load the circuit.

Resistor 0.5W 4.3M ohm Applications

• Long RC delays and timers: 4.3 MΩ with 1 µF gives a time constant of about 4.3 seconds
• Bias and feedback resistors in CMOS and op-amp circuits
• High-voltage dividers, using several resistors in series
• Bleeder resistors for filter capacitors
• Capacitive touch and proximity sensing

What's in the Box

• 5 × 4.3 MΩ 0.5 W resistors

Tip: Very high resistances are sensitive to leakage, so keep the board clean and dry; flux residue and finger grease can create parallel paths that change the value. Do not hold both multimeter probes with your fingers while measuring.
