1K Ohm 1/4W Film Resistor - Pack of 10

The 1K Ohm 1/4W Film Resistor is a commonly used passive electronic component designed to provide a fixed resistance of 1KΩ in electrical circuits. It can be used to control current, reduce voltage, divide signals, and establish appropriate resistance values in various electronic designs.

With a 0.25W power rating, it is suitable for many low-power circuits such as LED projects, sensor interfaces, transistor circuits, Arduino projects, and basic analog or digital electronics.

The through-hole leads allow easy installation on breadboards and prototyping boards. This makes the resistor particularly convenient for students and electronics enthusiasts who frequently build and modify circuits.

How It Works

A resistor limits the flow of electrical current through a circuit. The 1KΩ resistance value determines how much the resistor opposes current flow according to Ohm's law.

For example, when connected to a 5V supply, a 1KΩ resistor would theoretically allow approximately 5mA of current when connected directly across the supply, assuming an ideal circuit. The resistor can therefore be used for applications such as limiting current through an LED or establishing a desired voltage in a voltage-divider circuit.

Important Notes

• Do not exceed the rated 1/4W (0.25W) power dissipation.
• Verify the resistor value before installing it in a circuit.
• Resistance and physical appearance may vary slightly between production batches.
• For high-power applications, use a resistor with an appropriate higher wattage rating.
• Product images may be illustrative and may differ slightly from the actual product.
