Resistor 0.5W 430K ohm (5 pcs)

The Resistor 0.5W 430K ohm is a through-hole fixed resistor with a resistance of 430 kΩ and a power rating of 0.5 W, sold in a pack of 5. This E24 value is handy for setting op-amp gain, building low-current voltage dividers and adjusting timing circuits when the standard 390 kΩ or 470 kΩ values do not fit.

Resistor 0.5W 430K ohm Specifications

• Resistance: 430 kΩ (430,000 ohms)
• Power rating: 0.5 W (1/2 W)
• Current at 5 V: about 11.6 µA
• RC time constant with 10 µF: about 4.3 s
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 430K ohm Applications

• Gain-setting and feedback resistors in op-amp amplifiers
• Low-current voltage dividers for battery and sensor monitoring
• RC timing and 555 timer circuits
• Transistor bias networks
• Electronics education and prototyping

What's in the Box

• 5 × 430 kΩ 0.5 W resistors

Tip: In an inverting op-amp amplifier the gain is Rf / Rin, so 430 kΩ in the feedback path with a 10 kΩ input resistor gives a gain of 43. Resistors have no polarity, so they can be fitted either way round.
