GRM188R61H474KA12D

The GRM188R61H474KA12D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers 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 consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Multilayer ceramic capacitors like this model are constructed from alternating layers of ceramic dielectric material and metal electrodes, then sintered into a compact package. The resulting component offers high capacitance density, making it possible to achieve significant capacitance values in a small physical footprint. The GRM188 designation indicates this capacitor uses an 0603 inch (1.6 mm × 0.8 mm) surface-mount package, a standard size that balances ease of handling with space efficiency on modern printed circuit boards. The "R61" coding within the part number references the specific dielectric formulation and electrical performance class of this capacitor. Murata's R61 class represents capacitors optimized for general-purpose applications where stable capacitance across a wide operating temperature range and reasonable tolerance are required. These capacitors typically exhibit moderate temperature coefficient characteristics, making them suitable for power supply filtering, signal coupling and decoupling, and general energy storage applications in circuits that don't require the precision of specialty dielectric classes. Engineers specify this particular part number when designing circuits that require reliable, cost-effective capacitance in a compact package without the premium pricing of specialized alternatives. The 0603 form factor is particularly popular in modern electronics because it can be efficiently assembled using standard surface-mount technology equipment, reducing manufacturing costs while maintaining high reliability. Common applications for capacitors in this category include decoupling and bypass filtering in digital logic circuits, smoothing and energy storage in power management circuits, AC coupling in audio and analog signal paths, and EMI/RFI suppression in various industrial and consumer devices. The multilayer construction provides low equivalent series resistance (ESR) and low equivalent series inductance (ESL) compared to older through-hole capacitor technologies, making these components well-suited for high-frequency applications. Murata's manufacturing quality and consistency, combined with the standardized 0603 package compatibility, make the GRM188R61H474KA12D a reliable choice for design engineers seeking a dependable passive component for mid-range performance applications where both cost and reliability are important design considerations.
