Typical Applications & Why This Part Fits

• Power Supply Output Filtering: With its 250V rating and 0.33µF capacitance, this MLCC effectively filters high-frequency noise in DC-DC converter outputs and input bulk circuits.
• Automotive ECU Decoupling: The X7R dielectric ensures stable capacitance over a wide temperature range (–55°C to +125°C), making it suitable for engine control units and infotainment modules.
• Industrial Power Management: The 1812 package provides a robust footprint for soldering in high-voltage battery management systems and motor drive circuits.

Key Features & Advantages

• 250V High-Voltage Rating: Enables direct use in 48V bus, PoE, and industrial power rails without additional derating.
• X7R Temperature Stability: Capacitance variation of ±15% over –55°C to +125°C ensures consistent performance in harsh environments.
• Compact 1812 Case Size: Balances high voltage capability with a modest footprint, saving PCB space compared to larger radial or film capacitors.
