GRM155R71H392KA01D

The GRM155R71H392KA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to the GRM series, which represents Murata's established line of general-purpose ceramic capacitors widely used in industrial, automotive, consumer electronics, and telecommunications applications. Multilayer ceramic capacitors are fundamental passive components found in virtually every modern electronic device. They function to store electrical energy, filter signals, decouple power supplies, and stabilize voltage in circuits. The MLCC construction uses multiple alternating layers of ceramic dielectric material and metallic electrodes, allowing manufacturers to achieve relatively high capacitance values in compact packages. The GRM155R71H392KA01D uses a 1206 package format, which is one of the most common surface-mount device (SMD) sizes in modern electronics manufacturing. This package size makes the capacitor suitable for high-density circuit boards where space efficiency is important, while remaining large enough for automated assembly processes and reasonable repair accessibility. The 1206 form factor strikes a practical balance between miniaturization and handling requirements in both production and maintenance scenarios. This specific part number indicates a capacitor with Class II dielectric characteristics, which Murata designates with the "R7" code. Class II ceramics offer higher capacitance density compared to Class I alternatives, making them the preferred choice for coupling, decoupling, and filtering applications where exact capacitance stability is less critical than achieving compact size and cost efficiency. These capacitors are commonly specified in power supply filtering circuits, bypass applications, and signal conditioning stages throughout industrial equipment and consumer devices. Engineers might select the GRM155R71H392KA01D specifically when designing circuits that require reliable performance in mainstream commercial and industrial temperature ranges. The combination of the established GRM series reputation, proven reliability in high-volume manufacturing, the practical 1206 package size, and the specific capacitance value make this part a standard choice for design engineers looking to minimize component procurement complexity while maintaining quality standards. Murata's GRM series capacitors undergo rigorous quality testing and are manufactured to strict international standards, making them suitable for applications where component reliability directly impacts system performance. This part would typically appear in applications ranging from automotive electronics and industrial control systems to power management modules and communication equipment where stable, cost-effective capacitive performance is required.
