MLCC KR355WD7LP225MV01L

What is KR355WD7LP225MV01L MLCC?

The KR355WD7LP225MV01L is a high-voltage, SMD multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 2.2 μF capacitance, 450 V DC rating, X7T dielectric, and ±20% tolerance, with the exact package designation 2SMD. RoHS compliant, it is designed for robust energy storage and decoupling in power-intensive circuits.

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

Typical Applications & Why This Part Fits

• DC‑Link Bus Filtering: The 450 V rating and 2.2 μF capacitance make it ideal for smoothing ripple currents in inverter or converter stages.
• LED Lighting Drivers: Its high‑voltage capability (450 V) and X7T stability ensure reliable operation in constant‑current offline LED supplies.
• Industrial Power Modules: The compact SMD form–factor (2SMD) with ±20% tolerance provides a cost‑effective solution for bulk decoupling in 3‑phase motor drives.

Key Features & Advantages

• High Voltage + Capacitance Density: 450 V withstand voltage combined with 2.2 μF in a small‑footprint SMD package reduces PCB space by eliminating multiple lower‑voltage caps.
• X7T Dielectric Stability: Offers predictable capacitance over –55°C to +125°C with only ±15% drift, critical for resonant converters.
• RoHS & Lead‑Free Compliance: Full environmental compliance for global shipping, avoiding redesign for future regulations.

Frequently Asked Questions

1. Q: What makes KR355WD7LP225MV01L different from a standard 450 V MLCC?
   A: Its 2.2 μF value is unusually high for a 450 V MLCC, enabled by Murata’s advanced thin‑layer technology, offering bulk decoupling where conventional caps only give nF‑range.
2. Q: Is KR355WD7LP225MV01L RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead‑free.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply for the KR355WD7LP225MV01L.
