Resistor 0.25W 51 ohm (10 pcs)

The Resistor 0.25W 51 ohm is a through-hole fixed resistor with a resistance of 51 Ω and a power rating of 0.25 W, sold in a pack of 10. Low values like 51 Ω are close to the 50 Ω impedance used in RF and test equipment, so they are often used to terminate signal lines, damp ringing on fast digital signals and limit current in low-voltage circuits.

Resistor 0.25W 51 ohm Specifications

• Resistance: 51 Ω
• Power rating: 0.25 W (1/4 W)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 10 pieces

Resistor 0.25W 51 ohm Applications

• Terminating 50 Ω signal and test lines
• Series damping resistors on clock and data lines
• Current limiting in low-voltage circuits
• Gate resistors for MOSFET drivers
• Electronics education and prototyping

What's in the Box

• 10 × 51 Ω 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 51 Ω, the 0.25 W limit is reached at only about 3.6 V across the resistor (about 70 mA), so check the power (P = V² / R) before using it with 5 V or more across it.
