GRM219C80J106ME39D

The GRM219C80J106ME39D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to Murata's GRM series, which is widely specified in consumer electronics, industrial equipment, and telecommunications applications where reliable energy storage and signal filtering are required. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronics. They function to store electrical charge, filter noise from power supplies, couple and decouple AC signals, and stabilize voltage in circuits. The compact size and low cost of MLCCs make them the most commonly used capacitor type in mass-produced electronic devices, from smartphones and computers to industrial control systems and automotive electronics. The GRM219C80J106ME39D features a 0805 package size, which refers to its surface-mount footprint measuring approximately 2.0mm by 1.25mm. This moderate size offers a practical balance between component density and ease of handling during assembly. The 0805 package remains popular in modern designs because it accommodates automated pick-and-place manufacturing while providing sufficient lead spacing for reliable soldering and rework. The part designation indicates a capacitor rated for 80V operation in the X7R dielectric class. X7R ceramics provide stable capacitance across temperature ranges typical of industrial and consumer applications, making them suitable for general-purpose use where temperature stability is important but extreme performance is not required. The "J" in the part number indicates a 5% capacitance tolerance, which is standard for general industrial applications where exact values do not require tighter control. Engineers typically specify this exact part number when designing circuits that require 80V rated capacitors in a compact 0805 footprint with standard tolerances and reliable performance across normal operating temperature ranges. Common reasons for selecting this specific component include space constraints on circuit boards, the need for high-volume, cost-effective production, compatibility with standard automated assembly processes, and Murata's reputation for consistent quality and long-term availability. This capacitor is commonly used in power supply filtering, bypass applications, signal conditioning circuits, and general decoupling throughout industrial and consumer electronics. Its widespread use means that engineers, procurement specialists, and manufacturers are familiar with its performance characteristics and can confidently specify it for applications requiring stable mid-voltage capacitance in a reliable, proven package format.
