Panasonic Automotive Systems introduced a new low-ESR, high-temperature special conductive polymer aluminum capacitor with low ESR and wide temperature range to ensure that the device is suitable for demanding applications.
As part of the SP Caps series, the ESR of the new HX series device is as low as 4.5mohm and the operating temperature range is -55C to + 125C, which means that the device has a service life of 10 years at 85C. The ripple current rating of the device is 8.5Arms, which ensures that they are subject to high stress levels.
The HX series SP capacitors have a capacitance range of 15uF to 560uF, and have always been suitable for voltages from 2V to up to 25V. They do not show capacitance drift over the entire temperature range, and there is no DC bias. Since no derating is required, in some designs, the use of HX series devices will reduce the number of BOMs. The company said that compared with tantalum devices, SP capacitors show more stable performance in the temperature and frequency range, due to the self-healing mechanism, so the reliability is higher and not flammable.
Panasonic European Polymer Capacitor Product Manager Motoshi Imai said: "These devices are ideal for a variety of applications, including input / output filtering in power converters and regulators, power and battery decoupling, and clock circuits. Their high temperature rating makes them Very suitable for use in servers, base stations and industrial PCs, but they are small enough for wearable, wireless and IoT designs. "
