What are the advantages of using silicone potting compound for power controllers?
The application of silicone potting compounds in power controllers has demonstrated their versatility, making them an indispensable component in the electronics industry. As a high-performance sealing material, silicone potting compounds not only offer exceptional protection against water, dust, and electrical insulation but also exhibit outstanding resistance to temperature variations and aging.

Core advantages of silicone potting compounds:
I. Wide-temperature-range stability
Available at -50℃~250℃ Long-term operation, coupled with the high- and low-temperature shock experienced during the start-up and shutdown of the power controller, will not result in cracking or delamination due to thermal expansion and contraction.
II. Excellent Electrical Insulation Performance
It has high dielectric strength, effectively isolating the risk of leakage current between components and traces on the circuit board, making it particularly suitable for high-voltage power modules.
III. Anti-aging and Environmental Resistance
UV-resistant, resistant to high humidity and heat, and chemically corrosion-resistant—suitable for outdoor or humid environments without yellowing or chalking, ensuring long-term reliable operation of the power controller.
IV. Stress Buffering Characteristics
After curing, it becomes an elastomer that can absorb vibrations and shocks generated during power supply operation, protecting sensitive components such as chips and capacitors and reducing the failure rate during transportation and use.
V. Thermal Conduction and Heat Dissipation
Thermal conductivity of silicone potting compound 0.6–3.5 W/m·K Help the power controller quickly dissipate heat and prevent overheating-induced shutdowns.
