GRM155R61E105KA12D

The GRM155R61E105KA12D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronics, serving critical functions in filtering, decoupling, coupling, and energy storage circuits. The GRM155R61E105KA12D features a compact 0805 package size (1.25mm × 2.0mm), making it ideal for space-constrained PCB designs where miniaturization is important without sacrificing performance. This package size represents a standard in industrial and commercial electronics, offering a good balance between ease of handling during assembly and space efficiency on the board. The part number nomenclature reveals several key characteristics. The "155" designation indicates this capacitor is designed for 16 volt operation. The "R61" refers to the dielectric material and voltage rating class, positioning this as a mid-range voltage device suitable for general power supply applications, logic circuits, and analog signal processing. The "E105" indicates the capacitance value and tolerance specifications, placing this component in a common capacitance range used throughout the electronics industry for decoupling and filtering applications. Murata's GRM series capacitors are specified across demanding industrial and commercial sectors because they offer reliable performance, consistent quality, and broad availability. Engineers select this exact part number when they require a proven, established component with excellent temperature stability and low equivalent series resistance (ESR) characteristics. The ceramic dielectric material provides stable performance across typical operating temperature ranges, making it suitable for both indoor and moderately harsh industrial environments. This capacitor would typically be found in power supply filtering networks, where it works alongside larger bulk capacitors to suppress high-frequency noise and stabilize voltage rails. It's also commonly used in signal conditioning circuits, clock distribution networks, and general board-level decoupling applications where its compact size and electrical characteristics provide optimal performance. The GRM155R61E105KA12D represents a standard, mature component choice for engineers seeking reliable passive component performance without premium pricing. Its widespread use in established designs and broad availability make it a practical specification for both prototype development and high-volume production environments.
