Power Your Innovations with Hongda HCE Series Supercapacitors

2025-09-28

In the fast-paced world of electronics, reliable energy storage is non-negotiable. Hongda Capacitors’ HCE Series Electric Double Layer Supercapacitors emerge as a game-changer, blending robust performance, versatile applications, and long-lasting durability to meet the demands of modern tech.

Designed for efficiency, the HCE Series (coin-type) boasts a rated voltage of 5.5V and a rated capacitance of 0.33F (with a tolerance of -20%~+80%), making it ideal for both energy storage and high-current scenarios. Its compact dimensions (11.5×5×6.4mm) fit seamlessly into space-constrained designs, while a wide operating temperature range of -25℃~+70℃ ensures stability in harsh environments—from freezing industrial sites to warm automotive cabins.

Performance is where the HCE Series truly shines. It delivers a nominal current of 0.029A and a max current of 0.033A, with an AC internal resistance of just 40Ω (@1kHz) for minimal energy loss. Rigorous testing confirms its resilience: 500,000 charge-discharge cycles at room temperature (with ≤30% capacitance change), 1000-hour high-temperature load resistance (+70℃, ≤5.0V), and stable performance in damp heat (40℃, 90-95% RH for 240h).

Versatility is another key strength. The HCE Series powers a wide range of devices:

Backup Power: RAM modules, car recorders, smart meters, and digital cameras.

Energy Storage: UPS systems, security equipment, communication devices, and small appliances.

High-Power Applications: Electric vehicles, smart grid controls, and locomotive ignition systems.

Backed by compliance with global standards (QC/T 741-2014, DL/T 1652-2016, IEC62391-1-2006).

Hongda’s HCE Series is a trusted choice for engineers and manufacturers worldwide.
 

Also we offer other type of supercapacitors which cross to Eaton, Elna, Lelon, Vinatech, Panasonic...
