RoHS compliant, it is designed for reliable decoupling and filtering in high-voltage applications where capacitance stability is essential.

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

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 250V rating and 10000PF value make it ideal for snubber or decoupling circuits in industrial power modules, reducing voltage spikes.
• Automotive EV Battery Management: U2J dielectric ensures stable capacitance under temperature variations, critical for BMS sensing and filtering in 48V/400V systems.
• Industrial Sensor Interfaces: Low ESR of U2J material supports high-frequency noise suppression without significant self-heating, even at ±20% tolerance for cost‑effective designs.

Key Features & Advantages

• High Voltage Rating (250V): Accommodates demanding power rails while minimizing the risk of dielectric breakdown.
• U2J Dielectric: Offers near‑linear temperature coefficient (±120ppm/°C) – excellent for timing circuits and resonant applications.
• ±20% Tolerance: Balances performance and cost, allowing flexible use in decoupling where absolute precision is not required.

Frequently Asked Questions

1. Q: What makes KCA55W7UMF103ML01L different from a standard MLCC?
   A: It combines a 250V voltage rating with Murata’s U2J formulation, providing higher stability and lower voltage coefficient than typical X7R capacitors of similar size.
