Resistor 0.25W 91 ohm (10 pcs)

The Resistor 0.25W 91 ohm is a through-hole fixed resistor with a resistance of 91 Ω and a power rating of 0.25 W, sold in a pack of 10. This low E24 value is used for LED current limiting on 3.3 V outputs, as a gate resistor for MOSFETs and as a series resistor on signal lines in Arduino and ESP32 projects.

Resistor 0.25W 91 ohm Applications

• Red LED indicators on 3.3 V ESP32 outputs
• Gate resistors for MOSFETs driven from Arduino or ESP32
• Series resistors on signal lines
• Electronics education and prototyping

What's in the Box

• 10 × 91 Ω 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 91 Ω, the 0.25 W limit is reached at about 4.8 V across the resistor (about 52 mA), so never connect it directly across a 5 V supply. A red LED on a 3.3 V output through 91 Ω draws about 14 mA.
