Polymer capacitors boost power stability in compact electronics

March 5, 2026

With ultra-low ESR, the SP-Cap JX polymer capacitors from Panasonic Industry deliver long life and high ripple tolerance, and are engineered for stability as well as reliability.

The SP-Cap JX series of surface-mount conductive polymer aluminum electrolytic capacitors are designed for stable power delivery in space-constrained applications. The JX series supports rated voltages of 2V, 2.5V, 4V, and 6.3V, making it suitable for bulk decoupling and energy storage in modern compact consumer electronics.

 

Thanks to the low ESR, SP-Cap JX capacitors minimize voltage drop and waste heat, ensuring high power integrity for fast-switching processors and regulators. The capacitors also tolerate high ripple currents up to 10.2Arms without performance loss, supporting stable dc power rails for demanding loads. The high single-unit capacitance can potentially reduce the number of parallel capacitors required, saving board space while maintaining tight voltage regulation.

 

The JX series has long life, combined with a wide operating-temperature range, to ensure durable performance over years of operation.
