GRM1885C1E821JA01D

The GRM1885C1E821JA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This part belongs to Murata's General Purpose (GRM) capacitor family, designed for widespread industrial and consumer electronics applications where reliable, compact energy storage and filtering are required. Multilayer ceramic capacitors like this one are fundamental building blocks in modern electronics. They function by storing electrical energy in an electric field between multiple layers of ceramic dielectric material and metal electrodes. These capacitors are essential for power supply filtering, signal coupling and decoupling, noise suppression, and timing circuit stabilization across virtually every category of electronic equipment. The GRM1885 series uses a 1808 case size in metric dimensions, providing a compact footprint suitable for high-density circuit boards while offering practical handling characteristics for both manual and automated assembly. This size category represents an excellent balance between miniaturization and ease of manufacturing, making it popular in applications ranging from consumer electronics to industrial control systems. The X7R (or equivalent) dielectric formulation typical of this series offers relatively stable capacitance across standard operating temperature ranges, making it suitable for general-purpose applications that don't require ultra-specialized performance characteristics. The part number coding indicates this is a 820 picofarad (pF) capacitor, suggesting use in radio frequency, high-frequency coupling, or precision timing applications where smaller capacitance values are preferred. General Purpose MLCCs in this value range serve applications including RF impedance matching, EMI filtering, oscillator tank circuits, and sensitive analog signal conditioning. Engineers specify this exact part when they need the specific combination of capacitance value, package size, voltage rating, and temperature stability that Murata's quality and consistency provide. The GRM series is widely recognized across design communities, supported by extensive technical documentation, and available through established supply chains, reducing development risk and simplifying component qualification. For designers working on space-constrained applications requiring reliable passive component performance at moderate cost, this capacitor family represents a proven, economical choice. The 1808 package also facilitates easy rework and repair during manufacturing and field service, making it practical for applications where component replacement may be necessary. Whether specified for military/aerospace-grade designs, industrial automation, telecommunications infrastructure, or consumer products, this component class has demonstrated decades of reliability in demanding operating environments.
