LIFECYCLE: ACTIVE

\- HISTORICAL BACKGROUND: Murata Manufacturing Co., Ltd. was founded in Kyoto, Japan, in 1944 by Akira Murata. The company began as a ceramic materials and electronic component manufacturer and developed into one of the world's major suppliers of passive electronic components, including ceramic capacitors, inductors, filters, sensors, and radio-frequency components.

  Murata's early technological development concentrated on ceramic materials and their electrical characteristics. The company's expertise in ceramic processing became increasingly important as radio communications, television manufacturing, industrial electronics, and semiconductor-based equipment expanded during the twentieth century.

  Ceramic capacitors became widely adopted because they offered compact dimensions, reliable electrical characteristics, and compatibility with high-volume electronic manufacturing. Early ceramic capacitors were commonly manufactured as discrete leaded components, but advances in ceramic materials and production methods enabled increasingly smaller multilayer devices.

  Multilayer ceramic capacitors, commonly called MLCCs, use alternating layers of ceramic dielectric material and internal metallic electrodes. The internal electrodes are connected to external terminations, allowing multiple capacitive layers to operate together within a single compact component.

  This construction made it possible to increase capacitance while reducing physical dimensions. Multilayer ceramic technology became especially important in computers, telecommunications equipment, industrial controls, automotive electronics, and portable electronic devices.

  During the late twentieth century and early twenty-first century, the electronics industry's increasing use of surface-mount assembly encouraged the development of smaller capacitors with higher capacitance values and improved manufacturing consistency.

  Murata became a major developer and producer of miniature multilayer ceramic capacitors, supporting the electronics industry's transition toward smaller printed circuit boards and higher component densities.

  The 0402 surface-mount package represents one stage in this miniaturization. Measuring approximately 1.0 x 0.5 mm, the package allows capacitors to be installed in areas where larger traditional components would be impractical.

  Murata developed specialized capacitor families for different applications, including general-purpose electronics, automotive equipment, power supply circuits, communications hardware, and industrial systems.

  The GRT series was developed for automotive infotainment, comfort equipment, and industrial electronic applications. These capacitors are designed to meet applicable electrical and reliability requirements, including AEC-Q200 qualification.

  The GRT155R61E105KE01D combines a 1uF capacitance value with a 25V rating and X5R temperature characteristic in a miniature 0402 package.

  The X5R dielectric belongs to the Class II ceramic dielectric family. It provides relatively high capacitance density in compact packages, making it useful for decoupling, bypassing, and power supply filtering applications.

  Unlike Class I ceramic dielectrics, X5R capacitance can vary with temperature, applied DC voltage, and operating conditions. Engineers must account for these characteristics when selecting capacitors for circuits requiring a specific effective capacitance.

  The development of high-capacitance miniature MLCCs helped support increasingly compact automotive control modules, mobile communications equipment, computing hardware, industrial controllers, and electronic instrumentation.

  Murata's GRT capacitor family continues to serve automotive and industrial electronics applications, reflecting the company's long history of ceramic materials research, passive component miniaturization, and electronic manufacturing technology.
