Typical Applications & Why This Part Fits

• Power Supply Decoupling: The 1.5 µF capacitance at 16V provides effective ripple suppression in DC/DC converter output stages, maintaining low impedance across a wide frequency range thanks to X7R stability.
• I/O Line Filtering: Its 0805 size fits easily on dense PCBs for signal conditioning, while the ±10% tolerance ensures consistent noise attenuation in high-speed interfaces.
• Automotive Infotainment Modules: As Murata’s GCM series, it meets rigorous reliability standards; the 16V rating safely handles transient voltages typical in 12V vehicle systems.

Key Features & Advantages

• X7R Dielectric: Offers ±15% capacitance change over -55°C to +125°C, making it suitable for temperature-varying environments without performance drift.
• Compact 0805 Footprint: Saves board space while providing 1.5 µF – a balance often required in portable and IoT devices where area is at a premium.
• Low ESR: Murata’s advanced ceramic construction minimizes equivalent series resistance, improving high-frequency decoupling efficiency and reducing heat generation.
