Resistor 0.25W 150K ohm (10 pcs)

The Resistor 0.25W 150K ohm is a through-hole fixed resistor with a resistance of 150 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. It is a common choice for scaling higher voltages down to a safe level for a microcontroller's analog input while drawing very little current from the source.

Resistor 0.25W 150K ohm Applications

• Voltage dividers: 150 kΩ over 100 kΩ scales 12 V down to 4.8 V for a 5 V Arduino ADC
• High-value pull-up and pull-down resistors
• Inverting op-amp amplifiers with a gain of −15 (10 kΩ input resistor)
• RC timing circuits: 150 kΩ × 10 µF = 1.5 s
• Electronics education and prototyping

What's in the Box

• 10 × 150 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. At 5 V a 150 kΩ resistor draws only about 33 µA. Check a divider's output with a multimeter before connecting it to an analog pin, so the pin never sees more than its supply voltage.

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