GRM188R61C105KA12D

The GRM188R61C105KA12D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive components. This capacitor belongs to Murata's GRM series, which is widely recognized across industrial and consumer electronics applications for reliable performance and consistent quality. Multilayer ceramic capacitors are fundamental passive components used in virtually every electronic circuit. The GRM188R61C105KA12D is engineered for general-purpose decoupling, filtering, and signal coupling applications where compact size and cost-effectiveness are important design considerations. These capacitors work by storing and releasing electrical charge, helping to stabilize voltage supplies, filter noise, and protect sensitive circuitry from transient voltage spikes. The "188" designation in the part number refers to the package size, which is the 0603 imperial equivalent—one of the most common surface-mount component packages used in modern electronics manufacturing. This compact footprint makes the part ideal for space-constrained designs while remaining compatible with standard pick-and-place assembly equipment. The small form factor, combined with Murata's manufacturing precision, allows engineers to integrate high-density component placement without sacrificing reliability. This capacitor is suitable for a wide range of industrial, automotive, telecommunications, and consumer electronics applications. Typical uses include power supply filtering on printed circuit boards, bypass capacitance near integrated circuit power pins, AC coupling in audio and signal processing circuits, and EMI suppression in switching power supplies. Engineers often specify capacitors from Murata's GRM series when they require proven reliability in high-volume production environments, where supply chain continuity and consistent performance across large production runs are critical. The GRM series is known for robust construction and stable electrical characteristics across operating conditions. Murata's multilayer ceramic technology delivers excellent volumetric efficiency, allowing higher capacitance values in smaller packages compared to some alternative dielectric materials. This makes the GRM188R61C105KA12D particularly attractive for modern compact electronics where PCB real estate is at a premium. Engineers select this specific part number when they need a standard, readily available capacitor with proven field reliability, excellent manufacturing consistency, and the confidence that the component will meet their application's performance requirements across production volumes. The established design history of Murata's GRM series also reduces qualification time for many industrial and OEM customers.
