GRM155R61A105A

The GRM155R61A105A is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This component belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across industrial electronics, consumer devices, and telecommunications equipment. As a ceramic capacitor, this component functions as an energy storage and filtering element in electronic circuits. It works by storing electrical charge between two conductive plates separated by a ceramic dielectric material, enabling rapid charge and discharge cycles. Capacitors of this type are essential for power supply filtering, decoupling, AC coupling, and signal conditioning applications where reliable performance and compact size are critical. The GRM155R61A105A features a 1206 package size (0.126" × 0.063"), making it a surface-mount device suitable for automated assembly on printed circuit boards. The 1206 package represents an industry-standard format that balances component density with ease of handling and repair, making it popular in both high-volume manufacturing and field-serviceable applications. The ceramic dielectric technology used in this series provides stable capacitance across a wide range of operating conditions, with characteristics suitable for general-purpose filtering and energy storage rather than specialized applications requiring extreme temperature stability or voltage linearity. Engineers typically specify this capacitor in applications requiring modest capacitance values with cost-effective manufacturing. Common use cases include power supply filtering on logic boards, decoupling near integrated circuit power pins, bypassing high-frequency noise, and general energy storage in industrial control systems. The ceramic MLCC construction offers excellent frequency response, low equivalent series resistance, and reliability over extended operating lifespans when properly applied within rated electrical limits. When selecting between alternatives, engineers often choose Murata's GRM series for its consistent quality, wide availability, and proven performance record across harsh industrial environments. The 1206 package size offers flexibility for designers working with board space constraints while maintaining adequate surface area for soldering and thermal dissipation. The broad temperature operating range typical of this series supports applications in temperature-variable industrial settings without significant performance degradation. For applications requiring exact electrical specifications, component selection should reference the appropriate datasheet for this specific part number to ensure voltage rating, capacitance value, tolerance, and temperature coefficient meet circuit requirements. The GRM155R61A105A represents a reliable choice for OEM manufacturers and field engineers seeking dependable ceramic capacitor performance in standard industrial applications.
