2MΩ 1/4W resistor

A 2MΩ (2,000,000 ohms) 1/4 watt resistor is a high-resistance component designed to offer a resistance of 2 million ohms and handle up to 0.25 watts of power. It is used in electronic circuits for applications such as setting bias levels, voltage division, and as part of signal processing.

Key Features:

• Resistance: 2MΩ
• 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: 2MΩ
• 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 in electronic circuits to avoid excessive current flow.
• Voltage Division: Used in voltage divider circuits to achieve specific output voltages.
• Pull-up/Pull-down Resistors: Ensures defined logic levels in digital circuits.
• Biasing: Sets appropriate biasing levels for transistors and other semiconductor devices.

Usage:

1. Placement: Place the resistor in the appropriate position on the circuit board.
2. Insertion: Insert the leads through the board holes or slots.
3. Soldering: Solder the leads securely and trim any excess.
4. Verification: Check the resistor’s value with a multimeter to ensure it matches the required specifications.

Caution:

• Power Dissipation: Do not exceed the 0.25-watt power rating to avoid overheating.
• Voltage Rating: Ensure the resistor’s voltage rating is sufficient for your circuit’s requirements.
• Handling: Handle carefully to prevent damage during installation and soldering.
