Resistor 0.5W 1.8M ohm (5 pcs)

The Resistor 0.5W 1.8M ohm is a fixed through-hole resistor with a resistance of 1.8 MΩ and a 0.5 W power rating, sold in a pack of 5. It is a common E12 value for discharging capacitors, biasing CMOS oscillators and building voltage dividers that draw only a few microamps.

What's in the Box

• 5 × 1.8 MΩ 0.5 W resistors

Tip: The 0.5 W limit is only reached at around 950 V across a 1.8 MΩ resistor, so in practice the maximum working voltage is the limit. Check it, and use several resistors in series, when working with high voltages.

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