Resistor 0.5W 51K ohm (5 pcs)

The Resistor 0.5W 51K ohm is a through-hole fixed resistor with a resistance of 51 kΩ and a power rating of 0.5 W, sold in a pack of 5. This high value lets very little current flow, which makes it useful for voltage dividers on battery and sensor inputs, op-amp gain networks and high-value pull-up or pull-down resistors.

Resistor 0.5W 51K ohm Specifications

• Resistance: 51 kΩ (51,000 ohms)
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 51K ohm Applications

• Voltage dividers for measuring battery or supply voltage with an analog input
• Gain and feedback resistors in op-amp circuits
• Low-current pull-up and pull-down resistors
• RC timing networks with capacitors
• Electronics education and prototyping

What's in the Box

• 5 × 51 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 51 kΩ, the 0.5 W limit is only reached at about 160 V across the resistor, so power is rarely a concern in low-voltage circuits.
