Resistor 0.5W 510K ohm (5 pcs)

The Resistor 0.5W 510K ohm is a through-hole fixed resistor with a resistance of 510 kΩ and a power rating of 0.5 W, sold in a pack of 5. This high value keeps current very low, so it suits battery voltage dividers, weak pull-up or pull-down resistors, long RC time constants and biasing in high-impedance amplifier circuits.

Resistor 0.5W 510K ohm Specifications

• Resistance: 510 kΩ (510,000 ohms)
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Current at 5 V: about 10 µA
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 510K ohm Applications

• Voltage dividers that measure battery voltage with very low drain
• Weak pull-up and pull-down resistors
• Long delays in 555 timer and RC timing circuits
• Biasing op-amp and transistor inputs
• Electronics education and prototyping

What's in the Box

• 5 × 510 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. When a 510 kΩ divider feeds a microcontroller analog input, the high source resistance can make readings unstable, so add a 100 nF capacitor from the analog pin to ground.

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