82Ω 1/4W resistor

35.00

An 82Ω (ohm) 1/4 watt resistor is a fixed resistor with a resistance value of 82 ohms and a power dissipation rating of 0.25 watts (1/4W). It is used in electronic circuits to limit current, divide voltages, and perform other functions requiring precise resistance.

Key Features:

  • Resistance: 82Ω
  • Power Rating: 1/4W (0.25 watts)
  • Tolerance: ±5% (commonly), though other tolerances such as ±1% are available
  • Temperature Coefficient: Typically ±100ppm/°C or ±200ppm/°C for general-purpose resistors

Technical Specifications:

  • Resistance: 82Ω
  • 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: Standard through-hole resistors typically come in axial packages (e.g., 1/4W size)
  • Material: Carbon film, metal film, or metal oxide, depending on the specific resistor type

Applications:

  • Current Limiting: Used to limit the amount of current flowing through a circuit.
  • Voltage Division: Employed in voltage divider circuits to create specific voltage levels.
  • Biasing: Used in transistor biasing circuits to set operating points.
  • Signal Conditioning: Used in various signal processing applications to adjust signal levels.
  • LED Protection: Used to limit current through LEDs to prevent damage.
  • Timing Circuits: Paired with capacitors in RC timing circuits.

Usage:

  1. Determine Placement: Identify the location on the circuit board where the resistor is needed.
  2. Insert Resistor: For through-hole resistors, insert the leads into the appropriate holes on the PCB.
  3. Soldering: Solder the leads to the PCB pads and trim any excess lead length.
  4. Verify Installation: Ensure the resistor is securely soldered and check for proper resistance with a multimeter if needed.

Caution:

  • Power Dissipation: Do not exceed the power rating (0.25W) to prevent overheating and potential damage.
  • Voltage Rating: Ensure the voltage across the resistor does not exceed its voltage rating.
  • Handling: Handle with care to avoid physical damage to the resistor body and leads.
