30Ω 1/4W resistor

30Ω 1/4W resistor

35.00

A 30Ω (ohm) 1/4 watt resistor is a fixed resistor designed to provide a resistance value of 30 ohms with a power dissipation rating of 0.25 watts (1/4W). It is commonly used in electronic circuits for various applications such as current limiting, voltage division, and biasing.

Key Features:

  • Resistance: 30Ω
  • Power Rating: 1/4W (0.25 watts)
  • Tolerance: ±5% (commonly), with ±1% available for precision types
  • Temperature Coefficient: Typically ±100ppm/°C or ±200ppm/°C for general-purpose resistors

Technical Specifications:

  • Resistance: 30Ω
  • Power Rating: 1/4W (0.25 watts)
  • Tolerance: ±5% (J), ±1% (F), depending on the specific resistor 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 type

Applications:

  • Current Limiting: Used to limit the amount of current flowing through a circuit or component.
  • Voltage Division: Employed in voltage divider circuits to achieve a specific voltage level.
  • Biasing: Sets the operating points of transistors or other components.
  • Load Resistor: Acts as a load in various electronic circuits and devices.

Usage:

  1. Placement: Position the resistor on the PCB or within the circuit.
  2. Insertion: Insert the resistor leads into the appropriate holes or slots.
  3. Soldering: Solder the leads to the circuit board or connections and trim excess leads.
  4. Verification: Use a multimeter to check the resistance and ensure correct installation.

Caution:

  • Power Dissipation: Ensure the resistor does not exceed its 0.25-watt power rating to prevent overheating.
  • Voltage Rating: Verify that the resistor’s voltage rating is suitable for your application.
  • Handling: Handle carefully to avoid physical damage.
