39KΩ 1/4W resistor

A 39KΩ (ohms) 1/4 watt resistor is used in electronic circuits to provide a specific resistance value with a power dissipation capacity of up to 0.25 watts. It is essential for precise current limiting, voltage dividing, and signal conditioning.

Key Features:

• Resistance: 39KΩ
• 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: 39KΩ
• Power Rating: 1/4W (0.25 watts)
• Tolerance: ±5% (J), ±1% (F), depending on 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: Protects other components by controlling the current flow.
• Voltage Dividers: Used to set specific voltage levels in circuits.
• Biasing: Provides correct operating conditions for electronic components.
• Signal Conditioning: Adjusts signals to the necessary levels.

Usage:

1. Placement: Insert the resistor into the circuit board or component slot.
2. Insertion: Pass the leads through the board’s holes or slots.
3. Soldering: Solder the leads securely and trim any excess.
4. Verification: Measure the resistor’s value with a multimeter to confirm it matches the specified resistance.

Caution:

• Power Dissipation: Ensure the resistor does not exceed the 0.25-watt power rating to prevent overheating.
• Voltage Rating: Confirm the resistor’s voltage rating is adequate for your application.
• Handling: Handle carefully to avoid damage during installation.
