GRM31BR73A472KW01L

The GRM31BR73A472KW01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a comprehensive family of surface-mount ceramic capacitors designed for high-reliability applications across consumer electronics, industrial equipment, and telecommunications infrastructure. Multilayer ceramic capacitors are fundamental building blocks in modern electronic circuits, serving critical functions including filtering, decoupling, energy storage, and signal coupling. The GRM31 designation indicates this is a compact surface-mount device with a 1206 package size (3.2mm × 2.5mm), making it suitable for space-constrained applications while maintaining reasonable capacitance and voltage ratings. This package size represents a balance between miniaturization and ease of handling during manufacturing processes. The BR designation in the part number refers to the dielectric material type, which is optimized for specific performance characteristics relating to temperature stability and voltage linearity. Murata's GRM series capacitors are engineered to meet demanding industrial specifications, making them suitable for applications requiring stable performance across varying temperature ranges and operating conditions. This particular capacitor would typically be specified by engineers in applications such as power supply decoupling on circuit boards, noise filtering in analog and digital circuits, impedance matching in RF applications, and as part of resonant circuits. The 1206 package size makes it especially common in consumer electronics, industrial control systems, automotive electronics, and communication equipment where component density and reliability are both important considerations. Engineers might select the GRM31BR73A472KW01L over alternatives based on several factors: Murata's reputation for consistent quality and long-term availability, the specific electrical characteristics offered by the BR dielectric material, compatibility with standard automated pick-and-place assembly equipment, and proven performance in high-volume production environments. The GRM series has extensive design-in history across numerous OEMs, providing confidence in long-term reliability and supply chain stability. For applications requiring high-temperature operation, enhanced voltage linearity, or strict capacitance stability across operating conditions, the GRM series offers proven solutions backed by comprehensive technical support and documentation. The 1206 package size also facilitates manual rework and repair if needed in manufacturing or field service scenarios, an advantage over smaller alternatives. This capacitor is suitable for engineers designing power management circuits, signal conditioning stages, and filtering networks where Murata quality standards and the specific performance envelope of the GRM31 series meet design requirements.
