What is GCM188R91H682KA37D MLCC?
The GCM188R91H682KA37D is a high-reliability SMD capacitor manufactured by Murata. Key specs include a capacitance of 6800PF, 50V rating, X8R dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable performance under high-temperature automotive and industrial environments.
✔ RoHS Compliant / ✔ 0603 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Automotive ECUs: The 6800PF value and X8R dielectric ensure stable filtering and decoupling in engine control units exposed to 150°C continuous operation.
- Industrial DC-DC Converters: With 50V rating and tight ±10% tolerance, this MLCC delivers consistent bypass performance on high-voltage power rails where ripple rejection is critical.
- Infotainment & Telematics: The compact 0603 footprint combined with 6800PF capacitance enables noise suppression on CAN/LIN bus lines without consuming excessive board space.
Key Features & Advantages
- X8R Temperature Stability: Maintains capacitance within ±15% from -55°C to +150°C, outperforming X7R for under-hood automotive placement.
- Murata Quality Assurance: Rigorous AEC-Q200 qualification ensures low failure rates in vibration and thermal shock environments.
- 0.01µF Class Precision: The 6800PF ±10% rating provides tight coupling accuracy for sensor signal conditioning circuits.
Frequently Asked Questions
- Q: What makes GCM188R91H682KA37D different from a standard X7R capacitor?
A: Its X8R dielectric extends the operating temperature ceiling to 150°C, making it suitable for engine bay applications where standard X7R parts would degrade. - Q: Is GCM188R91H682KA37D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free by design. - 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 with quick turnaround on 0603 MLCCs.
