Resistor 0.25W 27 ohm (10 pcs)

The Resistor 0.25W 27 ohm is a quarter-watt through-hole resistor with a resistance of 27 Ω, supplied in a pack of 10. 27 Ω is a standard E12 value that shows up as a gate resistor for MOSFETs, a damping resistor on fast signal lines and the set resistor of small constant-current circuits in Arduino and ESP32 projects.

Resistor 0.25W 27 ohm Specifications

• Resistance: 27 Ω (27 ohms)
• Power rating: 0.25 W (1/4 W)
• Value series: standard E12 value (also in the E24 series)
• Colour code: red, violet, black (4-band) or red, violet, black, gold (5-band), followed by the tolerance band
• Maximum current: about 96 mA at the full 0.25 W
• Type: fixed resistor, axial leads, through-hole
• Pack size: 10 pieces

Resistor 0.25W 27 ohm Applications

• MOSFET gate resistors that limit the current spike from a microcontroller pin
• LM317 constant-current source: 1.25 V / 27 Ω gives about 46 mA
• Emitter resistors in small transistor amplifiers and current sources
• RC snubber networks across small inductive loads in low-voltage circuits
• Electronics education and prototyping

What's in the Box

• 10 × 27 Ω 0.25 W resistors

Tip: Need a value that is not in the E12 range? Two 27 Ω resistors in parallel give 13.5 Ω and together handle 0.5 W, while two in series give 54 Ω. Resistors have no polarity, so either lead can go to either side.

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