GRM155R61A474KE15W

The GRM155R61A474KE15W is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the industry's leading capacitor producers. This component belongs to the GRM series, which encompasses general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Multilayer ceramic capacitors like this model are fundamental passive components used for energy storage, filtering, decoupling, and signal coupling in electronic circuits. The GRM series is designed for high-volume production environments where reliability and consistent performance are essential. These capacitors are constructed from multiple layers of ceramic dielectric material with alternating metal electrodes, allowing manufacturers to achieve relatively high capacitance values in compact packages. The part number structure indicates this is a 0402-case size capacitor, which measures approximately 1.0mm × 0.5mm. This small form factor makes it ideal for space-constrained applications including mobile devices, wearable electronics, compact IoT devices, and densely populated circuit boards where real estate is at a premium. The miniaturized design does not compromise on performance, making these capacitors suitable for both consumer and industrial-grade applications. Murata's GRM series ceramics are engineered to deliver stable performance across a range of operating conditions. These capacitors typically exhibit good frequency characteristics and low equivalent series resistance (ESR), making them effective for high-frequency filtering and power supply decoupling in digital circuits. The series is recognized for consistent dielectric performance and reliability under thermal cycling, which is particularly important in automotive and industrial environments where temperature fluctuations are common. Engineers typically specify this exact part number when designing circuits that require a specific capacitance value with the compact 0402 footprint, combined with Murata's proven manufacturing quality and supply chain reliability. The GRM series has become an industry standard in many applications, offering designers confidence in long-term availability and consistent performance. This familiarity also means extensive reference designs and application notes exist, reducing development risk. The 15W variant designation indicates this part is optimized for general industrial and consumer applications. When selecting between Murata's capacitor options, engineers consider factors such as the required capacitance value, voltage rating, temperature coefficient, and mechanical package size. The GRM155R61A474KE15W serves as a versatile building block for modern electronics, particularly where compact size and reliable performance are both required specifications.
