Resistor 0.25W 91K ohm (10 pcs)

The Resistor 0.25W 91K ohm is a through-hole fixed resistor with a resistance of 91 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. Together with a 10 kΩ resistor it gives a divide-by-10.1 ratio, close to 10:1, which lets a 3.3 V ADC on an ESP32 measure supplies up to about 33 V.

Resistor 0.25W 91K ohm Applications

• Near-10:1 voltage dividers for measuring supply voltages
• Inverting op-amp amplifiers with a gain of −9.1 (10 kΩ input resistor)
• High-value pull-up and pull-down resistors
• Transistor and op-amp bias networks
• Electronics education and prototyping

What's in the Box

• 10 × 91 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. At 5 V a 91 kΩ resistor draws only about 55 µA, and the 0.25 W limit is only reached at about 151 V, so power is not a concern in low-voltage circuits.
