Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Thermal runaway leading to component failure
Cause: Inadequate heat dissipation due to poor thermal design, dust accumulation on heatsinks, or operation in high ambient temperatures exceeding specifications, causing overheating of MOSFETs, capacitors, or ICs.
Electrolytic capacitor degradation
Cause: Extended operation at high temperatures or voltage stress beyond ratings, leading to electrolyte evaporation, increased ESR, reduced capacitance, and eventual open or short circuit failure.
Maintenance Indicators
  • Visible bulging or leaking of electrolytic capacitors on the PCB
  • Audible high-frequency buzzing or crackling sounds from the module, indicating potential transformer/core saturation or arcing
Engineering Tips
  • Ensure proper thermal management by maintaining clean heatsinks/fins, verifying adequate airflow in enclosures, and avoiding installation near heat sources to keep operating temperatures within manufacturer limits.
  • Implement periodic infrared thermography inspections to detect abnormal hot spots on components like MOSFETs, transformers, and capacitors, allowing proactive replacement before failure.
