MLCC GRM31CC81A476ME44K

What is GRM31CC81A476ME44K MLCC?

The GRM31CC81A476ME44K is a ceramic multi-layer capacitor (MLCC) manufactured by Murata (村田). Key specs include a ±20% capacitance tolerance and SMD packaging. RoHS compliant, it is designed for stable decoupling and filtering in space-constrained circuits.

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

Typical Applications & Why This Part Fits

• Power supply decoupling: The ±20% tolerance is fully acceptable for bulk bypass capacitors, ensuring steady voltage rails in MCU and FPGA designs.
• DC-DC converter output filtering: High capacitance density MLCCs like this one smooth ripple effectively, with the wide tolerance accommodating production variation without impacting performance.
• Consumer audio equipment: Used for coupling and supply rail filtering, the broad tolerance guarantees cost-effective operation in non-critical analog stages.

Key Features & Advantages

• Wide tolerance (±20%): Reduces component cost while maintaining adequate performance for general-purpose decoupling and filtering tasks.
• Murata manufacturing precision: Ensures reliable capacitance across temperature and voltage, backed by decades of MLCC leadership.
• Surface-mount package: SMD format supports automated assembly and high-density PCB layouts, ideal for modern compact electronics.

Frequently Asked Questions

1. Q: What makes GRM31CC81A476ME44K different from a standard MLCC?
   A: This part is characterized by its ±20% tolerance grade, which allows Murata to offer a cost-optimized solution for designs where tighter tolerance (e.g., ±10%) is not required, such as bulk decoupling.
2. Q: Is GRM31CC81A476ME44K 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 and flexibility for low-volume projects.
