What is GCM188R91H333KA37D MLCC?
The GCM188R91H333KA37D is a SMD capacitor manufactured by Murata. Key specs include 0.033µF capacitance, 50V rating, X8R dielectric, and ±10% tolerance. RoHS compliant, it is designed for reliable decoupling and filtering in high-temperature automotive and industrial electronics.
✔ RoHS Compliant / ✔ 0603 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Automotive Engine Control Units: With 0.033µF capacitance and X8R dielectric rated to 150°C, this MLCC ensures stable bypass filtering under hood where ambient temperatures exceed 125°C.
- Industrial Power Supplies: The 50V rating provides sufficient headroom for 24V rail decoupling, while the 0603 footprint saves PCB space in dense converter layouts.
- ADAS Sensor Modules: The ±10% tolerance maintains consistent performance across batches for critical timing and noise suppression circuits in camera and radar systems.
Key Features & Advantages
- X8R Dielectric: Guarantees capacitance stability from -55°C to +150°C, making it suitable for extreme temperature environments.
- Compact 0603 Package: Enables high-density board design without sacrificing electrical performance for miniaturized modules.
- 50V DC Rating: Provides robust margin for 12V and 24V systems, reducing derating concerns and improving long-term reliability.
Frequently Asked Questions
- Q: What makes GCM188R91H333KA37D different from a standard MLCC?
A: This Murata part uses X8R dielectric for extended temperature range up to 150°C, while standard X7R only supports 125°C, making it ideal for under-hood automotive apps. - Q: Is GCM188R91H333KA37D 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 full BOM kitting at SZYY, including fast prototyping supply for engineering samples.
