Introduction
In the smart lighting field, starting performance and long-term reliability in low-temperature environments are major challenges facing design engineers. Ordinary electrolytic capacitors experience severe capacitance degradation, increased ESR, and increased leakage current at -40°C. This results in high system energy consumption and a short lifespan, seriously impacting product competitiveness.
YMIN Chip Aluminum Electrolytic Capacitor Solution
- Root Cause Technical Analysis -
From a technical perspective, the root cause of the problem lies in:
1. Low-temperature electrolyte activity: Traditional electrolytes increase in viscosity and decrease in ionic conductivity at low temperatures.
2. Material temperature characteristics: The temperature coefficients of the dielectric and electrode materials do not match.
3. Package sealing: The shrinkage of the sealing material at low temperatures leads to performance degradation.
4. Lifespan mechanism: High temperatures accelerate electrolyte volatilization and oxide film degradation.
