MLCC GRM155C81A225ME44D

What is GRM155C81A225ME44D MLCC?

The GRM155C81A225ME44D is a multilayer ceramic capacitor (MLCC) manufactured by Murata (村田). Key specs include capacitance 2.2µF, rated voltage 10V, dielectric X6S, package size 0402, and tolerance ±20%. RoHS compliant, it is designed for high capacitance density in space-constrained circuits.

✔ RoHS Compliant  /  ✔ 0402  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Power decoupling in IoT modules: The 2.2µF value at 10V provides low-impedance decoupling for wireless SoCs, while the X6S (-55°C to +105°C) ensures stable capacitance over industrial temperature ranges.
• Portable battery-powered devices: Compact 0402 size saves PCB space, and the ±20% tolerance is sufficient for bulk bypass in wearables or hearing aids where board real estate is critical.
• High-frequency DC/DC converter output filtering: Murata’s advanced stacking technology reduces ESL/ESR, maintaining effective filtering at switching frequencies up to several MHz.

Key Features & Advantages

• X6S dielectric stability: Capacitance change of ±22% over -55°C to +105°C, ensuring reliable performance in automotive and industrial environments.
• Ultra-compact 0402 footprint: Occupies 1.0mm × 0.5mm, enabling dense component population in mobile or miniature designs.
• Low equivalent series resistance: Murata’s nickel electrode termination minimizes power loss and self-heating during ripple current operation.

Frequently Asked Questions

1. Q: What makes GRM155C81A225ME44D different from a standard X5R 2.2µF 0402?
   A: This part uses X6S dielectric, which offers wider temperature range (-55°C to +105°C) than X5R (-55°C to +85°C), making it suitable for automotive and industrial use. The ±20% tolerance is also typical for high-volume, low-cost decoupling.
2. Q: Is GRM155C81A225ME44D 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 this mium-sized MLCC.
