Typical Applications & Why This Part Fits

• Power decoupling in portable devices: The 4.7µF capacitance at 25V provides effective smoothing and noise filtering under varying loads, while the X6S dielectric ensures minimal capacitance shift from -55°C to +105°C.
• DC-DC converter output filtering: Its low ESR and stable 0603 footprint allow dense PCB layouts for compact power modules, delivering consistent filtering performance without derating.
• Automotive infotainment systems: The AEC-Q200-qualified design (implied by GRT series) and ±10% tolerance make it suitable for harsh automotive environments requiring reliable ceramic capacitors.

Key Features & Advantages

• X6S Dielectric: Offers superior capacitance stability over temperature compared to standard X5R, ensuring predictable circuit behavior in both low- and high-temperature conditions.
• 0603 Miniature Package: Occupies minimal board space while delivering 4.7µF capacitance, enabling thinner and smaller end-product designs.
• Murata Quality & Reliability: Manufactured under strict process controls with a long-term supply commitment, reducing obsolescence risk and ensuring consistent batch-to-batch performance.

Frequently Asked Questions

1. Q: What makes GRT188C81E475KE13J different from a standard 0603 X5R capacitor?
   A: The X6S dielectric provides a flatter capacitance-versus-temperature curve, retaining over ±22% capacitance change from -55°C to +105°C, whereas X5R typically only guarantees up to +85°C.
2. Q: Is GRT188C81E475KE13J RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, making it suitable for global regulatory requirements.
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 BOM kitting support and small-batch flexibility for prototyping and low-volume production.
