105°C Aluminum Electrolytic Capacitor vs 125°C - WEET WGD Series
Introduction
When selecting a 105°C aluminum electrolytic capacitor, engineers often compare it with 125°C types.
The key difference is not performance, but temperature capability.

Radial Aluminum Electrolytic Capacitor
A radial aluminum electrolytic capacitor has two leads on the same side and is widely used in through-hole PCB designs.
It is the most common form for power electronics applications.
WEET WGD Product Range:
WEET WGD offers radial aluminum electrolytic capacitors including:
WGD-LRH: 3000H to 5000H at 105°C: WEET-WGD-LRH-3000H-to-5000H-at-105C-Radial-Aluminum-Electrolytic-Capacitors-Low-Impedance
WGD-LEH: 1000H to 2000H at 105°C: WEET-WGD-LEH-1000H-to-2000H-at-105C-Radial-Aluminum-Electrolytic-Capacitors-Low-Impedance
WGD-LRG: 2000H to 3000H at 125°C: WEET-WGD-LRG-2000H-to-3000H-at-125C-Radial-Aluminum-Electrolytic-Capacitors-Low-Impedance
Conclusion
A 105°C aluminum electrolytic capacitor is suitable for most applications.
A 125°C version is only needed for high-temperature environments.
Choosing correctly improves reliability and cost efficiency.
