Resistor 0.25W 240K ohm (10 pcs)

The Resistor 0.25W 240K ohm is a through-hole fixed resistor with a resistance of 240 kΩ and a power rating of 0.25 W, sold in a pack of 10. It is often paired with a lower resistor in a divider that brings a Li-ion or 12 V battery voltage into the range of an ADC pin, and it also suits gain-setting and timing circuits.

Resistor 0.25W 240K ohm Applications

• Voltage dividers that scale Li-ion or 12 V battery voltage down for an ADC pin
• Setting gain in op-amp amplifiers and active filters
• Timing resistors in 555 timer and RC oscillator circuits
• Transistor biasing in small-signal amplifiers
• Electronics education and prototyping

What's in the Box

• 10 × 240 kΩ 0.25 W resistors

Tip: With 240 kΩ, the 0.25 W limit is only reached at about 245 V across the resistor, so it is very safe for 3.3 V, 5 V and 12 V circuits. When it feeds a microcontroller ADC, a 100 nF capacitor from the ADC pin to ground helps steady the readings.
