Description

The 5.1K Ohm Resistor is a widely used passive electronic component designed for through-hole mounting. With a resistance value of 5.1 kilohms (5100 ohms), it provides reliable current limiting, voltage division, and signal conditioning in various circuits. This resistor is part of the carbon film or metal film family (depending on specific manufacturer details) and is engineered for durability and consistent performance.

Key features include:

• Power Rating: 1/4 Watt (250 mW), suitable for low-power electronic applications.
• Tolerance: ±5%, ensuring a maximum variation of ±255 ohms from the nominal value, making it ideal for general-purpose usage.
• Temperature Coefficient: Typically in the range of ±200 ppm/°C (varies by manufacturer), ensuring stable operation over a range of temperatures.
• Construction: Encased in a cylindrical body with axial leads, the resistor features a protective coating that resists moisture, oxidation, and mechanical stress.
• Color Coding: The resistance value is marked using industry-standard color bands: Green, Brown, Red, and Gold (indicating 5.1K ohms with 5% tolerance).

Applications

• Voltage Regulation: Used in voltage divider circuits for stepping down voltages.
• Current Limiting: Protects LEDs, transistors, and ICs by limiting current flow.
• Signal Conditioning: Filters or adjusts signal levels in analog and digital circuits.
• Timing Circuits: Works with capacitors in RC timing and oscillator circuits.

Specifications
