MLCC GRM219R6YA475KA73D

What is GRM219R6YA475KA73D MLCC?

The GRM219R6YA475KA73D is a multilayer ceramic capacitor manufactured by Murata. Key specs include 4.7µF capacitance, 35V DC rating, X5R dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in space-constrained designs.

✔ RoHS Compliant  /  ✔ 0805 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• DC-DC Converter Output Smoothing: The 4.7µF capacitance at 35V provides sufficient ripple attenuation for step-down regulators in industrial and telecom modules without requiring bulky electrolytics.
• Power Rail Decoupling on Mixed-Signal Boards: X5R dielectric ensures stable capacitance across -55°C to +85°C, making it reliable for decoupling analog and digital supply rails in I/O interface circuits.
• USB-C & Battery Charging Paths: With a 35V rating well above typical 5V/9V USB rails, this 0805 MLCC offers robust margin for hot-plug events and load-dump transients in portable device power inputs.

Key Features & Advantages

• 4.7µF in 0805 Case: High capacitance density reduces board area by consolidating multiple lower-value caps into a single component, simplifying layout and reducing pick-and-place cost.
• 35V Voltage Rating: 2× to 3× derating margin over common 16V rails enhances long-term reliability and reduces the risk of dielectric breakdown under surge conditions.
• X5R Temperature Stability: ±15% capacitance change over -55°C to +85°C provides predictable performance in automotive cabin electronics and outdoor IoT endpoints.

Frequently Asked Questions

1. Q: What makes GRM219R6YA475KA73D different from a standard X5R 4.7µF cap?
   A: Murata’s internal electrode design and tight process control deliver lower ESR and higher ripple current capability than generic alternatives, especially at 35V where DC bias effects are minimized.
2. Q: Is GRM219R6YA475KA73D 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 flexible lot sizes for pre-production validation.
