Resistor 0.25W 51K ohm (10 pcs)

The Resistor 0.25W 51K ohm is a through-hole fixed resistor with a resistance of 51 kΩ and a power rating of 0.25 W, sold in a pack of 10. It is a standard value used where a fairly high resistance is needed, such as voltage dividers for measuring higher voltages, op-amp gain networks and RC timing circuits in Arduino and analog projects.

Resistor 0.25W 51K ohm Applications

• Voltage dividers for reading battery or supply voltages on an analog input
• Gain and feedback resistors in op-amp circuits
• RC timing with 555 timers and oscillators

What's in the Box

• 10 × 51 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 51 kΩ, the 0.25 W limit is only reached at about 113 V across the resistor, so power is rarely a concern in low-voltage circuits. On a 4-band resistor, 51 kΩ is marked green, brown, orange.
