• Power Rating: 1/4W (0.25 watts)
• Tolerance: ±5% (commonly), with ±1% available for precision applications
• Temperature Coefficient: Typically ±100ppm/°C or ±200ppm/°C

Technical Specifications:

• Resistance: 220Ω
• Power Rating: 1/4W (0.25 watts)
• Tolerance: ±5% (J), ±1% (F), depending on the type
• Temperature Coefficient: ±100ppm/°C or ±200ppm/°C
• Operating Temperature Range: -55°C to +155°C
• Body Size: Typically through-hole with axial leads (1/4W size)
• Material: Carbon film, metal film, or metal oxide, depending on the resistor type

Applications:

• Current Limiting: Used in circuits to limit the current flow to LEDs or other components.
• Voltage Dividers: Helps in creating specific voltage levels for different parts of a circuit.
• Biasing: Provides a precise resistance for setting bias levels in transistors and other components.
• Pull-up/Pull-down Resistors: Ensures proper logic levels in digital circuits.

Usage:

1. Placement: Insert the resistor into the correct position on the circuit board.
2. Insertion: Feed the leads through the board holes or slots.
3. Soldering: Solder the leads and trim any excess for a secure connection.
4. Verification: Use a multimeter to confirm the resistor’s value is correct.

Caution:

• Power Dissipation: Avoid exceeding the 0.25-watt power rating to prevent overheating and damage.
• Voltage Rating: Make sure the resistor’s voltage rating is appropriate for your circuit.
• Handling: Handle with care to prevent damage during installation and soldering.
