Description
5 PCS 25W 30 ohm Ceramic Cement Resistor
Key Features
- Package Contents: 5 ceramic cement resistors
- Power Rating: 25 Watts
- Resistance: 30 Ohms
- Tolerance: ±5%
- Body Material: Ceramic
- Construction: Wirewound resistor element housed in a ceramic case for high heat dissipation, shock resistance, and humidity resistance.
- Termination: Axial leads for through-hole mounting.
Replaces / Cross-Reference Part Numbers
- Can replace any ceramic cement resistor with matching electrical specifications (25W, 30Ω, ±5%).
- Suitable as a generic substitute for parts from manufacturers such as Smseace and BlueStars that meet the same power, resistance, and tolerance ratings.
Compatibility & Fitment
- Designed for general purpose use in a wide range of electronic circuits and devices.
- Commonly used in power supplies, audio amplifiers, inverters, and other equipment requiring power dissipation.
- Applications include:
- Computers
- Television sets
- Medical devices
- Automotive electronics
- DIY electronic projects
- Fitment is determined by matching electrical specifications and verifying physical dimensions for circuit board layout.
When to Replace
- Replace if the resistor is tested and found to be open (infinite resistance) or shorted.
- Replace if the measured resistance value is outside the ±5% tolerance range (28.5Ω to 31.5Ω).
- Replace if there are visible signs of physical damage, such as cracks, burns, or severe discoloration, which indicate overheating or component failure.
Installation Tips
- Verify the resistance of the new component with a multimeter before installation.
- Ensure the circuit is powered off and all capacitors are safely discharged before attempting removal or installation.
- Use appropriate soldering and desoldering techniques to avoid damaging the circuit board or the component.
- Mount the resistor with adequate space around it to allow for proper air circulation and heat dissipation. Cement resistors can operate at high temperatures.
