Kemet Electronics broadens automotive applications that take advantage of polymer electrolytes

Capacitors that comply with the AEC-Q200 standard can withstand the immunity and predictability of immunity tests for high energy load dump pulses

KEMET, the world's leading supplier of electronic components, announces the introduction of new devices with higher voltage ratings to expand its T598 polymer electrolytic capacitor product line. The addition of 35V devices with capacitance values ​​of 22 and 33μF marks the first time that Kemei Electronics has introduced such products to the market. The new AEC-Q200 compliant device extends the range of automotive applications that take advantage of polymer electrolytic devices and offers products that meet the critical requirements of voltage transients.

In addition, the polymer capacitor's ESR has a low temperature coefficient that helps ensure stable performance over its operating temperature range of -55 to +125 °C.

In addition, the capacitor's roll-off frequency is increased, allowing the device to hold the capacitor at a higher frequency position than the MnO2 device. Compared with liquid electrolyte devices, Chemmet's polymer electrolyte devices have a long service life and are ideal for harsh environmental conditions such as high temperature and high humidity typical automotive applications.

Dr. Philip Lessner, Senior Vice President and Chief Technology Officer of Kemet Electronics, said that the T598 series devices are fully compliant, and they have brought space for automotive power module designers. Efficiency, reliability under harsh conditions, and important advantages in longevity. Now, with the release of high-voltage devices and the fact that we are in the period of rapid growth in automotive electrification, we can meet more quantities and more diverse The demand for automotive modules."
