New series of automotive MLCCs in compact surface-mount packages

Kyocera AVX has expanded its line of KAM Series automotive MLCCs with the addition of 20 new components. Manufactured using miniaturisation and high-capacity atomisation technologies developed for smartphones and materials proven to maintain high-reliability performance in automotive environments, the KAM Series automotive MLCCs are offered in an extensive range of case sizes, capacitance values, and voltage ratings optimised for use in small, densely packed automotive circuits with fast processing speeds. These compact and lightweight surface-mount components minimise board space requirements and deliver capacitance values high enough to reduce capacitor component counts. These are crucial to helping automotive engineers overcome some of the many challenges posed by evolving EV, ADAS and ADS designs.

The new series are designed, manufactured, and tested to ensure they fulfil the high quality and reliability standards of automotive industry applications. They are compliant with the AEC-Q200 Stress Test Qualification for Passive Components standard, manufactured in IATF, QS9000, and VDA 6.4-approved facilities, and continuously tested in QA laboratories to ensure superior quality and performance. QA methods include 100% visual inspection, increased sampling for accelerated wave soldering, and lot-by-lot reliability testing. All of these series automotive MLCCs are also RoHS compliant and designed to be operated below the rated voltage.

The latest expansion of the series includes 20 new components. The new releases are available in four case sizes (0201, 0402, 0603, and 0805) with thicknesses extending from 0.33mm to 1.45mm, nickel/tin terminations, two dielectrics (X7R and X7T), four voltage ratings (4, 6.3, 10, and 16V), capacitance values extending from 0.1–22µF (±10%), and 7” reels loaded with paper or embossed plastic tape.

Ideal applications for the new automotive MLCCs include EV, ADAS, ADS, ECUs, powertrains, central gateway (CGW) communication nodes, cluster HUDs, door control units (DCUs), cameras, radar, LiDAR, memory, CPU/MPU decoupling, and other low-voltage safety systems with space constraints and high capacitance demands. They are also ideal for high-reliability applications outside the automotive industry.

With this latest extension, the MLCCs are now available with nine case sizes (0201, 0402, 0603, 0805, 1206, 1210, 1808, 1812, and 2220), two termination styles (nickel/tin and FLEXITERM), six dielectrics (C0G/NP0, X7R, X7T, X8R, X8L, and X8G), 16 voltages extending from 4V to 3,000V, capacitance values extending from 0.5pF to 22µF, eight capacitance tolerances spanning¬ ±0.1pF to ±20%, and 7” and 13” reels loaded with paper or embossed plastic tape. As such, the MLCCs are also ideal for use in hybrid automotive battery control, inverter, converter, motor control, and water pump applications; on-engine automotive applications; hybrid electric commercial applications, including emergency circuits, sensors, and temperature regulation devices; oil exploration applications; and other applications with a 150C operating requirement.

“Kyocera AVX has been a trusted supplier of automotive MLCCs for several decades and is very proud to introduce the new small-case-size, high-capacitance-value, wide-voltage-range, and AEC-Q200-qualified KAM Series automotive MLCCs to market,” said Kensuke Ikeda, senior manager – MLCC Development, Kyocera Corporation. “The number of MLCCs mounted in circuits related to EV, ADAS, and autonomous driving systems is steadily increasing, accelerating market demand for miniature components, and the voltage ratings of the ICs employed in these systems is decreasing, driving new demand for low-voltage MLCCs. Our evolving line of KAM Series capacitors satisfy these market demands. For example, when 5VDC is applied to our 0805 X7R dielectric MLCC rated for 10V and 10µF, it maintains 86.3% of its capacitance due to excellent DC bias characteristics. In addition, KAM Series MLCCs are precision engineered, manufactured, and tested to provide optimal solutions for EV, AD, and ADAS circuits and will continue to satisfy evolving automotive market demands with future series extensions.”
