What is the resistance value of this resistor?

The resistor has a nominal resistance of 1KΩ, which is equal to 1000Ω.

What is the power rating of the resistor?

The resistor has a power rating of 1/4W, or 0.25W.

What type of resistor is this?

It is a fixed film resistor with an axial through-hole construction.

Can a 1K resistor be used with an LED?

Yes. A 1KΩ resistor is commonly used for LED current limiting, although the appropriate resistance depends on the LED and supply voltage.

Can this resistor be used with Arduino and ESP32 projects?

Yes. It can be used in Arduino, ESP32, sensor, GPIO, pull-up, pull-down, voltage divider, and other low-power electronic circuits.

What happens if the resistor exceeds its 1/4W rating?

Exceeding the 0.25W power rating can cause excessive heating and may damage or permanently change the resistor value.

Important Notes

1KΩ = 1000Ω.
The 1/4W rating means the resistor should not be operated above its rated power under normal conditions.
Exact tolerance may vary by resistor batch; confirm the supplied component specification if a precise tolerance is required.
A resistor can become hot when dissipating significant power even when operated below its nominal rating.
Always calculate voltage, current, and power requirements before using the resistor in a circuit.
Product appearance and color bands may vary depending on the resistor manufacturer.
