Resistor 0.25W 43K ohm (10 pcs)

The Resistor 0.25W 43K ohm is a through-hole fixed resistor with a resistance of 43 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. As an E24 value between 39 kΩ and 47 kΩ, it lets you set divider ratios, timing periods and amplifier gains more precisely than the E12 series allows.

Resistor 0.25W 43K ohm Specifications

• Resistance: 43 kΩ (43,000 ohms)
• Power rating: 0.25 W (1/4 W)
• Value series: standard E24 value

Resistor 0.25W 43K ohm Applications

• Fine-tuning voltage divider ratios
• Transistor and op-amp bias networks
• Inverting op-amp amplifiers with a gain of −4.3 (10 kΩ input resistor)
• 555 timer and RC timing circuits: 43 kΩ × 10 µF = 0.43 s
• Electronics education and prototyping

What's in the Box

• 10 × 43 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. At 5 V a 43 kΩ resistor draws about 116 µA, and the 0.25 W limit is only reached at about 104 V across it (P = V² / R).
