Kemet extends tantalum polymer capacitors for ADAS
Reflecting trends for automotive and super computing, Kemet has expanded the temperature capability of T598 devices, a first-to-market tantalum polymer surface mount capacitor.
The capacitors address the stringent requirements and new challenges presented by advanced driver assistance systems (ADAS), autonomous driving in automotive applications and in digitalisation such as supercomputing, mobility services, connectivity and infotainment. T598 automotive grade polymer electrolytic devices combine multiple high-performance characteristics including high capacitance / voltage (CV) ratings, single digit equivalent series resistance (ESR), what is claimed to be class-leading ripple performance and extended life.
The AEC-200-qualified T598 devices have “excellent volumetric efficiency”, says Kemet, which in tandem with high capacitance values now up to 470mF, voltage offerings of 2.5 to 50V DC and new single digit ESR, means single components can be used where multiple devices must be used currently for board real estate and cost savings.
Robust and stable performance to 2000 hours at temperatures to 125 degrees C – equating to a mission profile of around 15 years – aligns with the requirements for vehicle applications ranging from ADAS features such as blind spot detection, adaptive cruise control and emergency brake assist, to safety systems including airbag occupant detection and alarm systems and electronic stability control.
Kemet believes the T598 series is an example of component technologies to satisfy performance and life requirements to meet the increase in electronic content on vehicles to enable ADAS, comfort and convenience and connectivity as well as the transition to hybrid and fully electrified powertrains, and fully autonomous driving.
Kemet offers a broad selection of capacitor technologies in the industry, and an expanding range of electromechanical devices, electromagnetic compatibility solutions and supercapacitors.
