What is GCM188C71C684KA64D MLCC?
The GCM188C71C684KA64D is a 0.68µF ±10% X7S ceramic capacitor rated at 16V, manufactured by Murata in the compact 0603 package. RoHS compliant, it is designed for high-reliability decoupling and filtering in automotive and industrial circuits where stable capacitance over temperature is critical.
✔ RoHS Compliant / ✔ 0603 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Automotive ECU Power Rails: With 0.68µF capacitance and X7S temperature stability (±22% from -55°C to +125°C), the GCM188C71C684KA64D effectively smooths supply noise in engine control units.
- Sensor Interface Filtering: The ±10% tolerance ensures predictable corner frequencies for anti-aliasing filters in pressure or temperature sensors.
- Portable IoT Modules: The 16V rating and 0603 footprint allow dense PCB layouts while maintaining margin for battery charging transients.
Key Features & Advantages
- Low ESR at High Frequencies: Murata’s MLCC structure provides low equivalent series resistance, improving ripple suppression in DC‑DC converters.
- X7S Dielectric: Offers wider capacitance variation limits than X7R, suitable for circuits requiring less drift over temperature.
- Automotive Grade (AEC‑Q200): The GCM series is qualified for harsh environments, reducing failure risks in under‑hood applications.
Frequently Asked Questions
- Q: What makes GCM188C71C684KA64D different from a standard X7R capacitor?
A: The X7S dielectric guarantees capacitance change of only ±22% over -55°C to +125°C, compared to ±15% for X7R over -55°C to +125°C, giving broader stability for automotive temperature swings. - Q: Is GCM188C71C684KA64D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead‑free. - Q: What is the MOQ? Can we get small batches?
A: We support small batch orders and fast BOM kitting at SZYY, including prototyping supply for the GCM188C71C684KA64D.
