High-voltage door handle capacitors: Safeguarding nondestructive testing equipment

Tens of thousands of exposures, consistent performance: The long-term reliability of high-voltage door handle capacitors safeguards non-destructive testing equipment. Non-destructive testing equipment, especially on automated production lines, undergoes thousands of repetitive tests day after day. Each test involves the high-voltage power supply being activated, exposed, and shut down. This high-frequency charge and discharge cycle places a severe strain on the durability of capacitors. Capacitor performance degradation directly leads to equipment degradation and even unplanned downtime.

Durability: The key to maintenance-free operation of non-destructive testing equipment.

The primary concerns of equipment manufacturers and end users are:

Can it withstand millions of charge and discharge cycles?

Will the capacitance value significantly degrade over time?

Will its lifespan be drastically shortened in high-temperature environments?

Our Longevity Gene: The Result of Materials Science and Processing

Our high-voltage door handle capacitors are designed with long-term reliability as a core goal from the outset:

Aging-resistant ceramic dielectric: Utilizing an optimized barium strontium titanate-based ceramic material, a doping process effectively suppresses dielectric aging, ensuring highly stable capacitance over decades.

Strengthened Electrode Interface: The advanced co-firing process of the metallized electrodes and ceramic dielectric creates a strong interface bond, effectively resisting fatigue damage caused by thermal expansion and contraction, as well as electrical stress.

Excellent Thermal Management: Low dissipation (DF) means lower self-heating. Combined with the heat dissipation advantages of the metal casing, this keeps the core temperature low. A rule of thumb: For every 10°C reduction in operating temperature, the lifespan doubles.

Promise and Verification:
Based on accelerated life testing data, we guarantee that our capacitors can withstand over one million full-load charge and discharge cycles at rated voltage and maximum operating temperature with a capacity degradation rate of less than 5%. This ensures that your device's testing performance will not be compromised by degradation of the core capacitor throughout its lifecycle.

Choosing us means choosing a solid commitment to long-term, stable operation, ensuring your equipment remains as good as new in harsh industrial environments.
