Resistor 0.25W 120K ohm (10 pcs)

The Resistor 0.25W 120K ohm is a through-hole fixed resistor with a resistance of 120 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. At 12 V it passes exactly 100 µA, a handy figure for designing low-current voltage dividers, bias networks and supply monitors in Arduino and ESP32 projects.

Resistor 0.25W 120K ohm Applications

• Low-current voltage dividers for battery and supply monitoring
• High-value pull-up and pull-down resistors
• Inverting op-amp amplifiers with a gain of −12 (10 kΩ input resistor)
• RC timing circuits: 120 kΩ × 10 µF = 1.2 s
• Electronics education and prototyping

What's in the Box

• 10 × 120 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. The 0.25 W limit would only be reached at about 173 V across this resistor (P = V² / R), so in hobby circuits power is never the limit; keep it away from mains voltage.

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