Resistor 5.1K Ohms 0.25W 5% Through-Hole

KTRON carbon-film through-hole resistor for general-purpose electronic circuits, prototyping and repair. The supplier specifies a 0.25 W power rating, 5% tolerance and carbon-film construction.

Key Specifications

  • Resistance: 5.1K Ohms
  • Power rating: 0.25 W (1/4 W)
  • Tolerance: ±5%
  • Technology: Carbon film
  • Mounting: Through-hole
  • Common marking: 5K1
  • Supplier-listed weight: 0.12 g

Applications

LED current limiting, voltage dividers, transistor biasing, pull-up and pull-down networks, signal conditioning, Arduino and ESP32 projects, breadboard prototyping, PCB assembly and electronics repair.

Usage Notes

Keep continuous resistor dissipation within the 0.25 W rating. Select a lower resistance only when the resulting current and power dissipation are acceptable for the circuit. For precision applications, use a resistor with a tighter tolerance.

Buying & Selection

Choose the resistance value based on the circuit calculation. The 5% tolerance means the actual resistance can vary around the nominal value. Confirm the color-band marking before installation when identifying loose resistors.
