1.5 Ohm 5W Ceramic Resistor ±5% – High Power Wirewound Resistor

The 1.5 Ohm 5W Ceramic Resistor is a high-power resistor intended for electronic circuits that require a relatively low resistance value with greater power dissipation capability than standard small resistors.

With a 1.5Ω resistance and 5W maximum power rating, it can be incorporated into current-limiting, load, power supply, amplifier, motor-control, and other power-related circuits. The ceramic body is suitable for applications where the resistor may become warm during normal operation.

The ±5% tolerance means the actual resistance can vary from the nominal 1.5Ω value within the specified tolerance range. Proper consideration of power dissipation and operating temperature is important when designing the circuit.

How to Use

1. Confirm that 1.5Ω is the required resistance for your circuit.
2. Calculate the expected current and power dissipation before installation.
3. Ensure the resistor's expected power dissipation remains within its 5W maximum rating.
4. Provide adequate ventilation or spacing because high-power resistors can become hot during operation.
5. Mount the resistor securely and keep heat-sensitive components away from it.

Important Notes

• The 5W rating is the maximum power rating, not a recommendation for continuous operation at 5W without considering temperature and cooling.
• High-power operation can cause the resistor body to become very hot.
• Do not touch the resistor immediately after operation.
• Allow adequate ventilation and clearance from heat-sensitive components.
• Verify resistance and power requirements before installation.
• Actual resistance may vary within the stated ±5% tolerance.
