How Much Do You Know About Radial Type Super Capacitor WUD?

What Is a Radial Type Super Capacitor?

WEET WUD Radial Type Super Capacitor is an electric double-layer capacitor with radial lead terminals, designed for easy PCB mounting and reliable energy storage.

WUD Radial Super Capacitor Construction and Working Principle

A radial super capacitor mainly consists of activated carbon electrodes, electrolyte, separator, and radial lead terminals.

Electric Double Layer

Unlike batteries that store energy through chemical reactions, super capacitors store energy through the electric double layer formed between the electrode and electrolyte interface.

This physical energy storage method enables faster charging speed and longer operating life.

How To Extend The Life Of WGD Long Life Aluminum Electrolytic Capacitor?

Aluminum electrolytic capacitors are widely used in power supplies, LED drivers, industrial equipment, and consumer electronics. However, the life of a WGD LRH Long Life Aluminum Electrolytic Capacitor can still be affected by operating temperature, voltage stress, storage conditions.

Here are three important factors that can help extend capacitor lifetime.

1. Reduce Operating Temperature

High temperature is one of the main factors that reduces aluminum electrolytic capacitor lifetime.

Excessive heat accelerates electrolyte evaporation, causing capacitance loss and increased ESR.

To extend capacitor life:

  • Improve ventilation and airflow 

  • Keep capacitors away from heat sources 

  • Select suitable temperature ratings, such as 105°C capacitors 

A lower operating temperature helps ensure stable performance for a WGD LRH Long Life Aluminum Electrolytic Capacitor.

2. Avoid Long-Term Storage

Long-term storage may affect the oxide layer inside aluminum electrolytic capacitors, which can increase leakage current after reactivation.

For better reliability:

  • Store capacitors in a dry environment 

  • Avoid extended storage periods 

  • Perform voltage reforming when necessary 

3. Keep Voltage Within the Rated Range

Operating beyond the rated voltage can damage the internal dielectric layer and shorten capacitor lifetime.

It is recommended to:

  • Keep sufficient voltage margin 

  • Avoid voltage spikes during startup 

  • Select suitable voltage ratings according to application requirements 

Conclusion

Proper application is essential to maximize the lifetime of aluminum electrolytic capacitors.

By controlling temperature, voltage, storage conditions, engineers can improve system reliability.

As an experienced OEM Capacitor Manufacturer, WEET provides reliable aluminum electrolytic capacitors designed for various electronic applications.

Why Do 1000uF 100V Electrolytic Capacitor Fail - WEET WGD Series

If you are looking for a reliable 1000uF 100V Electrolytic Capacitor, you likely know that capacitor quality is critical to circuit stability. However, even the best capacitors have a finite lifespan. 

As a China professional capacitor manufacturer, we often see premature failures caused by:

  • High Temperatures: The #1 killer. Every 10°C increase in temperature cuts the lifespan in half.

  • Overvoltage: Exceeding the rated voltage leads to dielectric breakdown and short circuits.

  • Excessive Ripple Current: Causes internal overheating and dangerous pressure buildup.

  • Natural Aging: The electrolyte slowly evaporates through the seals over time.

How to extend your circuit's life? Choose high-quality components. 

Our WGD series is engineered for exceptional reliability. As your trusted OEM Capacitor Manufacturer, WEET ensures every component meets the highest quality standards.
