Resistor 0.5W 300K ohm (5 pcs)

The Resistor 0.5W 300K ohm is a through-hole fixed resistor with a resistance of 300 kΩ and a power rating of 0.5 W, sold in a pack of 5. High values like this draw very little current, so they suit high-impedance voltage dividers, slow RC timing, bleeder resistors and input biasing in op-amp and CMOS circuits.

Resistor 0.5W 300K ohm Applications

• Voltage dividers for measuring higher voltages with very low current draw
• Long RC time constants with the 555 timer
• Bleeder resistors to discharge filter capacitors
• Biasing high-impedance op-amp and CMOS inputs
• Electronics education and prototyping

What's in the Box

• 5 × 300 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. The colour bands for 300 kΩ are orange, black, yellow. At 5 V only about 17 µA flows through 300 kΩ, so the power is tiny; at high voltages, check the resistor's maximum working voltage as well as its power rating.
