MLCC GRM155Z71A225ME43D

What is GRM155Z71A225ME43D MLCC?

The GRM155Z71A225ME43D is a multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 2.2µF capacitance, 10V voltage rating, X7R dielectric, and ±20% tolerance. RoHS compliant, it is designed for cost-effective decoupling and filtering in space-constrained circuits.

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

Typical Applications & Why This Part Fits

• Power rail decoupling in wearables: With 2.2µF in a tiny 0402 case and low 10V rating, it provides sufficient bulk capacitance for noise suppression on 3.3V or 1.8V rails in smartwatches and fitness trackers.
• DC-blocking in IoT sensor modules: The X7R dielectric ensures stable capacitance over a wide temperature range, while the ±20% tolerance keeps cost low for non-critical signal coupling in wireless sensor nodes.
• Output filter in low-power converters: 10V headroom and 2.2µF value make it ideal for smoothing PWM outputs in battery-powered DC-DC converters where board space is at a premium.

Key Features & Advantages

• 0402 Miniature Footprint: Saves critical PCB area for high-density designs, allowing passive component placement near active ICs.
• X7R Temperature Stability: Capacitance variation within ±15% from -55°C to +125°C, ensuring reliable performance across operating environments.
• High Volumetric Efficiency: 2.2µF in 0402 package provides industry-leading capacitance density for decoupling and bypass applications without increasing board layer count.

Frequently Asked Questions

1. Q: What makes GRM155Z71A225ME43D different from a standard X7R MLCC?
   A: This Murata part features a tightly controlled ±20% tolerance on 2.2µF, which makes it an economical choice for designs that don’t require tighter ±10% tolerance, while still delivering reliable X7R performance.
2. Q: Is GRM155Z71A225ME43D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, compatible with Pb-free soldering processes.
