The brand new capacitors deal with warmth, ripple, and vibration whereas saving house in powertrain and xEV programs. May this transformation the best way engineers design modules?
Design engineers engaged on automotive powertrain programs usually face ripple present, warmth, and house limitations. TDK Company’s B41699 and B41799 sequence of aluminum electrolytic capacitors assist tackle these challenges by decreasing the variety of capacitors wanted in modules corresponding to electrical energy steering, fan management, and transmission programs.
The first customers of those capacitors are automotive design engineers growing powertrain modules, digital management items, and different programs uncovered to excessive thermal and mechanical stress. They’re additionally related for engineers engaged on xEV platforms who want elements that steadiness compact design with lengthy working life and compliance with automotive requirements.
The corporate claims that the capacitors are designed to function at temperatures as much as +140 °C, making them appropriate for xEV platforms with 12-V programs the place vibration and thermal stress are key design issues. With capacitance values starting from 1800 µF to 13,000 µF and ripple present rankings as much as 34.6 A at 10 kHz and +125 °C case temperature, they supply steady power dealing with in compact layouts. Their low ESR at excessive frequencies additional helps effectivity in demanding energy circuits.
The B41699 model with axial leads and the B41799 model with a soldering star design permit versatile mounting in horizontal, vertical, or busbar configurations. Dimensions vary from 16 x 25 mm to 21 x 49 mm, overlaying completely different design wants. The capacitors supply greater than 4000 hours of helpful life at +125 °C below rated situations, with non-compulsory vibration stability as much as 60 g for harsher environments.
Constructed on TDK’s SIKOREL know-how, the capacitors present as much as 15 years of storage at +35 °C. Additionally they adjust to AEC-Q200 requirements and are RoHS-compatible, making certain reliability, qualification for automotive use, and long-term availability.
