What is GCM21BC71A475KA73L MLCC?
The GCM21BC71A475KA73L is a multilayer ceramic capacitor (MLCC) manufactured by Murata (村田). Key specs include 4.7µF capacitance, 10V DC rating, X7S dielectric with ±10% tolerance. RoHS compliant, it is designed for stable decoupling and smoothing in space-constrained automotive and industrial circuits.
✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata (村田) Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Automotive ECU Power Rails: The 4.7µF value and X7S temperature stability (up to 125°C) deliver consistent bulk capacitance for engine control unit decoupling under harsh thermal cycling.
- Industrial Sensor Modules: 10V voltage rating comfortably handles 3.3V/5V sensor bus ripple while the 0805 case enables dense PCB mounting near sensing elements.
- Battery Management Systems: Low equivalent series resistance from the MLCC construction reduces self-heating during charge/discharge pulses, prolonging system reliability.
Key Features & Advantages
- High Capacitance Density: 4.7µF in an 0805 footprint saves board space compared to larger case sizes, freeing up real estate for additional functionality.
- X7S Dielectric Stability: Capacitance change within ±22% from -55°C to +125°C ensures predictable filtering behavior across extreme operating temperatures.
- Murata Production Consistency: Strict process control yields tight tolerance (±10%) and low defect rates, reducing rework in high-volume assembly.
Frequently Asked Questions
- Q: What makes GCM21BC71A475KA73L different from a standard X7R MLCC?
A: The X7S dielectric provides a wider temperature range (-55°C to +125°C) with better capacitance retention at high heat compared to standard X7R, making it more suitable for under-hood automotive use. - Q: Is GCM21BC71A475KA73L RoHS compliant?
A: Yes, as a Murata (村田) 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 full BOM kitting at SZYY, including fast prototyping supply and flexible quantity allocation for engineering samples.
