Resistor 0.25W 220K ohm (10 pcs)

The Resistor 0.25W 220K ohm is a through-hole fixed resistor with a resistance of 220 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. At 220 kΩ it passes very little current, only about 23 µA at 5 V, which makes it a good choice for high-value pull-downs, low-drain voltage dividers and op-amp feedback networks in Arduino and ESP32 projects.

Resistor 0.25W 220K ohm Applications

• High-value pull-up and pull-down resistors where low current draw matters
• Battery voltage dividers for ESP32 and Arduino analog inputs
• Op-amp feedback: with a 10 kΩ input resistor, an inverting amplifier has a gain of −22
• Long RC time constants with small capacitors: 220 kΩ × 10 µF = 2.2 s
• Electronics education and prototyping

What's in the Box

• 10 × 220 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. Two 220 kΩ resistors in series form a 2:1 divider that draws under 10 µA from a 4.2 V Li-ion cell; add a 100 nF capacitor from the ADC pin to ground to keep the reading stable.

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