In conclusion, the choice of dielectric material in MLCCs is a critical factor that can significantly influence the performance of electronic circuits. By comprehensively understanding the characteristics and appropriate applications of Class 1 and Class 2 dielectrics, engineers can make informed choices that enhance the functionality and reliability of their designs.
Multilayer Ceramic Capacitors (MLCCs) are essential electronic components widely used in various applications, including automotive, telecommunications, consumer electronics, and industrial machinery. Their small size, high capacitance value, and excellent performance characteristics make them indispensable in modern electronic circuits.
One of the most critical applications for high temperature capacitors lies in the aerospace and defense sectors. Aircraft and missile systems must function flawlessly at elevated altitudes and in varying thermal dynamics. Using high temperature capacitors enhances operational reliability, ensuring critical systems remain functional during extreme maneuvers or temperature fluctuations. Similarly, in the automotive industry, as electric vehicles and advanced driver-assistance systems become prevalent, the need for components that can withstand high heat in tightly packed electronic architectures becomes increasingly vital. High temperature capacitors support systems that demand precision and durability, even in the harshest of driving conditions.
Technological advancements are addressing these challenges. Innovations in dielectric materials, manufacturing techniques, and design strategies continue to enhance the performance and reliability of MLCCs. The emergence of new dielectric formulations, such as those involving low-fire ceramics, aims to improve temperature stability and reduce microphonics.

In a world where technology is limited only by our imagination, the potential of high temperature capacitors remains boundless.
X7R ceramic capacitors are a type of multilayer ceramic capacitor (MLCC) characterized by their dielectric material, based on the X7R specification from the EIA RS-198 standard. The “X7R” classification indicates the capacitor’s temperature characteristics and stability. Specifically, X7R capacitors can operate within a temperature range of -55°C to +125°C with a tolerance of ±15% in their capacitance changes, making them suitable for a variety of environments.
The dielectric material in X7R capacitors typically consists of barium titanate combined with other ceramic materials to enhance their properties. This structure allows the capacitors to store and release electrical energy efficiently while maintaining stability across different temperatures. The capacitors are manufactured by layering alternating ceramic and metal layers, which increases their capacitance per volume and makes them compact and versatile for various electronic applications.
The local community is also set to benefit from the expansion, as the new facility will create approximately 200 new jobs, ranging from engineering to manufacturing positions. Circuit Functions Inc. is committed to fostering local talent and plans to partner with local universities and technical colleges to provide training programs that equip students with the necessary skills to succeed in the semiconductor industry.
The versatility of MLCCs leads to their use in numerous applications. In consumer electronics, they are commonly employed for decoupling and bypassing, helping to filter out noise and stabilize voltages in microprocessors and Integrated Circuits (ICs). In automotive electronics, as vehicles move towards advanced technologies such as electric and autonomous driving, the demand for reliable capacitors capable of withstanding harsh environments is elevated, further solidifying the role of MLCCs.
In today’s rapidly advancing technological landscape, the demand for reliable electronic components that can withstand extreme conditions is more significant than ever. Among these components, high temperature capacitors stand out as essential elements designed to perform effectively in elevated thermal environments. As industries push the boundaries of application scenarios—from aerospace to automotive—understanding the capabilities and benefits of high temperature capacitors becomes imperative.
