✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• High‑Voltage DC‑DC Converters: The 250V rating and 220pF value provide reliable snubber or bypass capacitance in flyback and boost sections.
• Automotive On‑Board Chargers: Murata’s robust construction ensures stable filtering at elevated voltages, matching the demands of EV power trains.
• Industrial Power Supplies: The ±10% tolerance and non‑standard SMD footprint allow flexible placement in tight PFC or LLC resonant circuits.

Key Features & Advantages

• High Voltage Rating (250V): Enables safe operation in circuits where standard 50V capacitors would fail, reducing design risk.
• Non‑Standard SMD Package: Offers mechanical compatibility with custom pad layouts, ideal for legacy or space‑constrained designs.
• Murata Reliability: Stringent manufacturing control ensures consistent capacitance over temperature and long‑term stability.

Frequently Asked Questions
