Resistor 0.25W 1.8M ohm (10 pcs)

The Resistor 0.25W 1.8M ohm is a through-hole fixed resistor with a resistance of 1.8 MΩ and a power rating of 0.25 W, sold in a pack of 10. Values just above 1 MΩ are common as load resistors for piezo sensors, bias resistors in CMOS oscillators and low-drain voltage dividers in battery-powered projects.

What's in the Box

• 10 × 1.8 MΩ 0.25 W resistors

Tip: At 1.8 MΩ the 0.25 W limit is only reached at about 670 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 1.8 MΩ.
