In high-voltage applications such as PV inverters, energy storage PCS, and industrial power equipment, reducing component costs is important—but preventing field failures is even more critical.
Common Challenges in High-Voltage Applications
1. Insufficient Voltage Margin
Frequent surge events and high operating voltages can cause dielectric breakdown if the capacitor lacks adequate voltage withstand capability.
2. Harsh Outdoor Environments
High humidity, temperature cycling, and long-term outdoor exposure may reduce insulation resistance and increase leakage current, affecting system reliability.
3. Excessive Heating at High Frequency
Large ESR values can generate excessive heat under high-frequency switching conditions, accelerating component aging and reducing equipment lifetime.
How JYH HSU (JEC) Helps Clients Improve Reliability
With over 23 years of manufacturing experience, JYH HSU provides high-voltage ceramic capacitors designed for demanding applications.
High Voltage Capability
Rated voltages up to 50kV provide additional design margin against surge stress, helping reduce development failures and improve EMC robustness.
Excellent Environmental Resistance
UL94V-0 flame-retardant epoxy encapsulation and operating temperatures from -55°C to +125°C ensure reliable performance in outdoor PV and energy storage environments, helping reduce field failures and after-sales costs.
Low ESR and Superior High-Frequency Performance
High-frequency C0G (NP0) dielectric formulations with low ESR and ESL effectively absorb transient spikes and minimize self-heating, contributing to longer system lifetime and improved stability.
At JYH HSU (JEC), we provide not only components, but also one-on-one engineering support to help customers optimize designs and improve long-term reliability.
