High capacitance values in compact, lightweight, 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, KAM Series automotive MLCCs are available 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, both of which are essential to helping automotive engineers overcome some of the many challenges posed by evolving electric vehicle (EV), advanced driver assistance system (ADAS) and automated driving system (ADS) designs.

KAM Series automotive MLCCs are designed, manufactured, and tested to ensure that they meet 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 quality assurance (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 KAM Series automotive MLCCs are also RoHS compliant and designed to be operated below the rated voltage.

The latest expansion of the KAM Series automotive MLCCs 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.

Suitable applications for the new KAM Series automotive MLCCs include electric vehicle (EV), automated driver assistance system (ADAS), and automated driving system (ADS) engine control units (ECUs), powertrains, central gateway (CGW) communication nodes, cluster heads-up displays (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 well suited for use in high-reliability applications outside of the automotive industry.

With this latest extension, the KAM Series automotive MLCCs is 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-in and 13-in reels loaded with paper or embossed plastic tape. As such, KAM Series MLCCs are also suited 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 150°C operating requirement.
