New low profile polymer capacitor family announced by Panasonic

January 23, 2015 New Product Introductions

SP-Cap range also available in high voltage and extended life versions 

Munich, November 2014: Panasonic Automotive & Industrial Systems has introduced a new low profile version of its SP-Cap range of speciality conductive polymer aluminium capacitors. Measuring just 0.9mm above the PCB, the devices (LR & SR series) are rated from 2V up to 6.3V with capacitance values of 68 to 220μF. Capacitance tolerance is ±20% (120Hz / +20degC).

Polymer capacitors present several advantages over other electrolytic devices”, explains Melanie Raimann, European Product Manager for Polymer Capacitors at Panasonic. “Thanks to their ultra-low ESR values, polymer capacitors have a low impedance near their resonance point which helps to smooth ripple voltage in power circuits. Polymer capacitors, unlike ceramic devices, suffer no capacitance drifts due to temperature changes and DC bias, so they remain stable over time. Lastly, polymer capacitors have a self-healing capability that eliminates failures due to cracking in the dielectric layer caused by electrical or mechanical stresses.”

Panasonic has also announced several other enhancements to the SP Cap devices. The company has upgraded the ripple current rating of the range, which can now handle up to 10.2Arms at 45degC, two and a half times higher than previous devices. Devices are also now available with up to 35V working range and focus devices in the family now feature an extended life to 2000 hours at 105degC that enables an application endurance of 10years at an ambient temperature 70degC.

Finally, several devices in the family will be available on smaller 500 piece reels to help with flexibility and prototyping requirements. A catalogue detailing all Panasonic’s new SP-Cap polymer aluminium capacitors can be freely downloaded at:
