Resistor 0.5W 180K ohm (5 pcs)

The Resistor 0.5W 180K ohm is a through-hole fixed resistor with a resistance of 180 kΩ and a power rating of 0.5 W, sold in a pack of 5. Its high value keeps current very low, which makes it a good choice for battery voltage monitoring, op-amp gain networks and RC timing in Arduino and ESP32 projects.

Resistor 0.5W 180K ohm Specifications

• Resistance: 180 kΩ (180,000 ohms)
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Current at 12 V: about 67 µA
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 180K ohm Applications

• Battery voltage dividers: 180 kΩ with 47 kΩ turns 12 V into about 2.5 V for an ESP32 or Arduino analog input
• Setting gain in op-amp amplifier stages
• RC timing in 555 timer and oscillator circuits
• High-value pull-up resistors in low-power designs
• Electronics education and prototyping

What's in the Box

• 5 × 180 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. At low voltages power is never a problem with this value: at 12 V it dissipates less than 1 mW, far below the 0.5 W rating.
