Resistor 0.25W 4.3M ohm (10 pcs)

The Resistor 0.25W 4.3M ohm is a through-hole fixed resistor with a resistance of 4.3 MΩ and a power rating of 0.25 W, sold in a pack of 10. Such a high value lets only a tiny current flow, which suits bleeding charge off capacitors, very low-drain voltage dividers and touch or proximity sensing with a microcontroller.

What's in the Box

• 10 × 4.3 MΩ 0.25 W resistors

Tip: At 4.3 MΩ the 0.25 W limit is only reached at about 1,040 V, so the resistor's maximum working voltage, not its power rating, is the real limit; check it before using the resistor across high voltages. When checking it with a multimeter, do not hold both leads with your fingers, because your body resistance in parallel makes the reading lower than 4.3 MΩ.

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