Kyocera AVX KAM Series MLCCs: The Ideal Choice for Automotive Electronics and High-Reliability Applications

With the rapid development of automotive electronics, fields such as electric vehicles (EVs), advanced driver-assistance systems (ADAS), and autonomous driving systems (ADS) demand increasingly high standards for electronic components. As a global leader in electronic component manufacturing, Kyocera AVX has introduced the KAM Series Multilayer Ceramic Capacitors (MLCCs), specifically designed to meet the stringent requirements of automotive electronics and high-reliability applications. With outstanding performance, a wide range of specifications, and exceptional reliability, this series has become a highly sought-after solution in the industry.

Product Features: A Perfect Blend of Performance and Reliability

Wide Voltage and Capacitance Range

The KAM series offers a voltage range from 4V to 3000V and a capacitance range from 0.5pF to 22µF, meeting diverse application needs from low voltage to high voltage and from small to large capacitance. This flexibility makes it suitable for various design scenarios, whether in compact devices with limited space or large modules requiring high power density.

Diverse Package Sizes

The series supports package sizes ranging from 0201 to 2220, with thicknesses ranging from 0.33mm to 1.45mm, accommodating a variety of complex designs. Ultra-small packages like 0201 are particularly advantageous in space-constrained applications while providing high capacitance values to reduce component count.

Superior Dielectric Materials

The KAM series uses various dielectric types, including C0G/NP0, X7R, X7T, X8R, X8L, and X8G. These materials offer different temperature characteristics and stability options to suit specific applications. For example, C0G/NP0 dielectric provides extremely low loss and high stability, while X7R dielectric offers higher capacitance across a wide temperature range.

High-Reliability Design

As an automotive-grade product, the KAM series complies with AEC-Q200 standards and undergoes rigorous quality testing, including batch-by-batch reliability testing and temperature cycling tests (up to 3000 cycles). Additionally, it features nickel/tin-plated terminations or FLEXITERM® flexible terminations that enhance mechanical stress resistance and thermal cycling performance for long-term stable operation.

Excellent DC Bias Characteristics

The KAM series maintains high capacitance even under low voltage conditions. For example, an 0805 package with a 10µF X7R capacitor retains 86.3% of its rated capacitance at a 5V DC bias. This characteristic makes it highly effective in low-voltage applications.

Typical Applications: Extensive Coverage in Automotive and Industrial Fields

Automotive Electronics

The KAM series is particularly well-suited for critical components in modern automotive electronics:

Electric Vehicles (EVs): Used in hybrid battery control systems, inverters, converters,  and motor control units.

Advanced Driver-Assistance Systems (ADAS) & Autonomous Driving Systems     (ADS): Includes engine control units (ECUs), power systems, central gateway communication nodes, radar systems, and LiDAR modules.

In-Vehicle Infotainment  Systems: Such as head-up displays (HUDs), door control units (DCUs),  and camera modules.

Industrial and Other High-Reliability Scenarios

Beyond automotive applications, the KAM series is widely used in industrial equipment and other demanding environments:

Emergency circuits, sensors, and temperature regulation devices.

Oil exploration equipment and other scenarios requiring operation at extreme temperatures up to 150°C.

Technical Advantages: Driving Innovation and Performance Optimization

Miniaturization with High Capacitance

Leveraging miniaturization technology developed for smartphones, Kyocera AVX has enabled the KAM series to achieve compact designs while offering high capacitance values. This not only reduces component count but also optimizes space utilization, providing greater design flexibility for engineers.

FLEXITERM® Flexible Termination Technology

This technology provides up to 5mm of mechanical flex capability, effectively preventing ceramic cracking caused by mechanical stress during PCB assembly or usage. It significantly enhances product reliability.

Superior Temperature Performance

With an operating temperature range of -55°C to 150°C, the KAM series ensures stable operation even in extreme environments. This feature makes it an ideal choice for applications such as oil exploration equipment that require robust performance under harsh conditions.

Conclusion: Industry-Leading Solutions

Kyocera AVX's KAM Series Multilayer Ceramic Capacitors stand out with their exceptional miniaturization capabilities, high reliability, and extensive specification options. They provide an ideal solution for modern automotive electronics and industrial equipment. Whether ensuring stable operation in harsh environments or offering flexible adaptation in complex designs, this series demonstrates remarkable technical strength. As automotive electronics continue to evolve, the KAM series will remain at the forefront of innovation, driving progress and unlocking new possibilities for the future.
