Lincolnwood, Ill. – Targeting space-constrained applications, Illinois Capacitor’s XMPL Series of polymer chip capacitors are available in a standard 7343 case size. The capacitors offer very low equivalent series resistance (ESR) and ripple current ratings, outperforming surface-mount electrolytics of greater size, said the company.
Because of the low ESR and high power density, fewer XMPL capacitors may be required in a circuit vs. electrolytic types, and depending on the application and values, one XMPL may replace two or three aluminum electrolytics, said Illinois Capacitor. “This difference can balance out the cost differential, while providing higher performance and longer life.”
Other features of the XMPL capacitors include longer life, greater stability with temperature changes and lower ESR at high frequencies. They are also lower in cost than tantalum capacitors of similar size in a standard 7343 package, according to Illinois Capacitor.
The polymer chip capacitors are available in standard capacitance values from 6.8 mF to 470 mF, with a maximum working voltage of 16 VDC. Load life is 1,000 hours at 105°C with full-rated voltage applied. The capacitors offer excellent high-frequency performance thanks to a solid polymer dielectric and specialized design. They are well suited to high-frequency compact power supplies, DC to DC converters and inverters. Other applications include decoupling and noise suppression in environmental controls, LED lighting, instrumentation, office automation and medical equipment.
Availability: The halogen-free and ROHS-compliant XMPL capacitors are available for sampling at illinoiscapacitor.com.
Pricing: Starts as low as $0.18 per piece in production volumes.
