• Tolerance: ±5% (commonly), with ±1% available for precision types
• Temperature Coefficient: Typically ±100ppm/°C or ±200ppm/°C for general-purpose resistors

Technical Specifications:

• Resistance: 33Ω
• 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 restrict the amount of current passing through a circuit or component.
• Voltage Division: Part of voltage divider circuits to achieve a desired voltage level.
• Biasing: Sets the operating points in transistor circuits or other electronic components.
• Load Resistor: Serves as a load in various electronic and electrical applications.

Usage:

1. Placement: Position the resistor on the PCB or in 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 any excess leads.
4. Verification: Use a multimeter to measure the resistance and confirm proper installation.

Caution:

• Power Dissipation: Ensure the resistor does not exceed its 0.25-watt power rating to avoid overheating.
• Voltage Rating: Check that the resistor’s voltage rating is appropriate for your circuit.
• Handling: Handle carefully to avoid physical damage and ensure correct operation.
