New polymer capacitors from Panasonic bring reliability and performance benefits in 10V tantalum applications

SP Caps are more stable and reliable; can facilitate BOM count reduction 

Munich, January 2015: Panasonic Automotive & Industrial Systems has introduced two new members of its SP Caps family of conductive polymer aluminium capacitors designed as a higher performance, cost-effective replacement for standard 10V MnO₂ tantalum capacitors.

As polymer capacitors do not require voltage derating, the new parts are rated at 6.3V. This also enables a parts reduction in some circuit designs. When compared to tantalum devices the SP Caps exhibit a more stable performance over temperature and frequency, are more reliable thanks to a self-healing mechanism, and are inflammable.

With the both available capacitance values (100uF & 150uF) we are also targeting the most prominent capacitance values for MnO2 tantalums. Important here is also, the part-no EEFCX0J221YR is on the paper a 220uF product, but as we have here a capacitance tolerance of -35% to +10% (typically the capacitance tolerance is ±20%) we use this product as 150uF.

EEJRX0J101R capacitors are rated at 100µF (±20%); EEFCX0J221YR devices are rated at 220µF (-35% to +10%). Operating temperature for both devices is -40 to +105degC. Comments Melanie Raimann, European Product Manager for Polymer Capacitors at Panasonic: “Because of the pricing, customers can simply switch devices and get a better performing more reliable product. Or they can redesign and save board space and cut BOM count as well.”
