220Ω 1/4W resistor

220Ω 1/4W resistor

45.00

A 220Ω (ohms) 1/4 watt resistor is used in electronic circuits to provide a resistance of 220 ohms with a power dissipation rating of up to 0.25 watts. It is suitable for use in various applications including current limiting, voltage division, and general-purpose use.

Key Features:

  • Resistance: 220Ω
  • 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.
