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

Technical Specifications:

• Resistance: 1.5MΩ
• 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: Controls current flow in electronic circuits to prevent damage.
• Voltage Division: Used in voltage divider circuits to achieve specific voltage levels.
• Pull-up/Pull-down Resistors: Ensures defined logic levels in digital circuits.
• Biasing: Sets biasing levels for transistors and other semiconductor devices.

Usage:

1. Placement: Position the resistor correctly on the circuit board.
2. Insertion: Insert the resistor leads through the board holes or slots.
3. Soldering: Solder the leads to the board and trim any excess leads.
4. Verification: Use a multimeter to check the resistor value and ensure it matches the required specification.

Caution:

• Power Dissipation: Do not exceed the 0.25-watt power rating to prevent overheating and damage.
• Voltage Rating: Verify the resistor’s voltage rating is adequate for your application.
• Handling: Handle with care to avoid mechanical damage during installation and soldering.
