Resistor 0.5W 39K ohm (5 pcs)

The Resistor 0.5W 39K ohm is a through-hole fixed resistor with a resistance of 39 kΩ and a power rating of 0.5 W, sold in a pack of 5. This higher value is handy for voltage dividers that measure battery or supply voltages with an analog input, for transistor and op-amp biasing, and anywhere only a small current should flow.

Resistor 0.5W 39K ohm Specifications

• Resistance: 39 kΩ (39,000 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 39K ohm Applications

• Voltage dividers for reading battery voltage on Arduino and ESP32
• Biasing transistors and op-amp circuits
• Setting gain in amplifier feedback networks
• RC timing networks, for example with the 555 timer
• Electronics education and prototyping

What's in the Box

• 5 × 39 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 39 kΩ, the 0.5 W limit is only reached at about 140 V across the resistor, so power is not a concern in normal low-voltage circuits.
