GRM219C81A475KE34D

The GRM219C81A475KE34D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, a leading producer of passive electronic components. This capacitor belongs to Murata's GRM series, which is widely recognized across industrial and commercial electronics applications for delivering reliable performance in compact form factors. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronic circuits. They function to store and release electrical energy, filter noise, decouple power supplies, and stabilize voltage levels across electronic systems. The GRM series is engineered to provide stable capacitance across a wide range of operating conditions, making these capacitors suitable for demanding applications where performance consistency is critical. The part number designation indicates this capacitor features an 0805 package size—a surface-mount format measuring 2.0mm by 1.25mm. This compact footprint makes it ideal for high-density PCB layouts where space constraints are a primary concern. Engineers frequently specify 0805 MLLCs in consumer electronics, industrial control systems, telecommunications equipment, and automotive electronics where board real estate is at a premium. The GRM219 series capacitors are commonly selected for general-purpose decoupling and filtering applications in power distribution circuits, signal conditioning stages, and timing circuits. Their multilayer ceramic construction provides good electrical performance across moderate frequency ranges, making them versatile for both DC bias and AC signal applications. These capacitors are particularly valued in industrial settings where long-term reliability and stable performance under operational stress are essential requirements. Engineers might specify this particular Murata part over generic alternatives due to several distinguishing factors. Murata's reputation for consistent quality and stringent manufacturing controls is a significant consideration in applications where component failure could impact system reliability or safety. The GRM series benefits from extensive qualification across industrial standards and has a proven track record in deployed systems. Additionally, Murata's broad component portfolio allows design teams to source complementary passive components from a single, trusted manufacturer, simplifying supply chain management and procurement processes. The 0805 package size also offers practical advantages during assembly and rework operations. Its dimensions strike an effective balance between handling ease for automated pick-and-place equipment and manual rework procedures, reducing manufacturing complexity compared to smaller package alternatives. For engineers working on industrial control systems, power electronics, or embedded systems where component reliability directly affects equipment uptime, the GRM219C81A475KE34D represents a proven, established solution from a manufacturer with deep expertise in ceramic capacitor technology.
