The 1 kΩ ±5% CFR 1/4 Watt Through-Hole Resistor is a passive electronic component designed to limit current flow within a circuit. It features a nominal resistance of 1 kilo-ohm (kΩ) with a tolerance of ±5%, indicating the potential variation in its actual resistance value. The CFR designation signifies a carbon film resistor construction, offering a cost-effective and widely used solution for general-purpose applications.

The color code for a 10K ohm resistor is typically brown, black, or green. The first digit (brown) represents 1, the second digit (black) represents 0, and the third digit (green) represents the multiplier of 10^2. So, the value is 10 * 100 = 1000 ohms or 1K ohms.

Applications:

• Current Limiting: By introducing resistance, it restricts current flow within a circuit, protecting sensitive components from overcurrent conditions.
• Voltage Division: In conjunction with other resistors, it can be used to create voltage dividers, generating precise reference voltages within a circuit.
• Biasing Circuits: It plays a role in establishing appropriate operating points for transistors and other active components.
• General-Purpose Applications: Its versatility makes it suitable for various electronic projects requiring a 1 kΩ resistance value.
