25W 30 Ohm Ceramic Cement Resistor (±5%)

Key Features

  • 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.

FAQ

Each resistor measures approximately 48mm in length, 10mm in width, and 10mm in height, with a lead length of about 25mm.
These resistors are rated for 25 watts with a resistance value of 30 ohms and a standard tolerance of ±5%.
These are primarily used in power supply circuits, motor speed controls, audio equipment, and LED lighting circuits where heat dissipation and high-power handling are required.
Ceramic cement resistors are designed for high-temperature stability and excellent heat resistance. The cement coating provides superior insulation and protection against moisture and vibration compared to standard film resistors.
Because these resistors operate at high temperatures, ensure they are mounted with adequate clearance from heat-sensitive components or plastic housings. It is recommended to leave a small gap between the resistor body and the PCB to allow for proper airflow and heat dissipation.
