✔ RoHS Compliant / ✔ SMD / ✔ Murata（村田） Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Automotive ECUs & ADAS: AEC-Q200 qualification ensures this capacitor endures thermal cycling and vibration, making it a trusted choice for safety-rated engine and driver-assistance electronics.
- Engine Control Modules: The ±10% tolerance delivers stable decoupling across temperature swings and voltage ripples, maintaining clean power delivery to sensitive microcontroller loads.
- Infotainment & Telematics: The SMD footprint suits automated high-density assembly, enabling compact layouts for connected-car modules that demand reliability in confined spaces.
Key Features & Advantages
- AEC-Q200 Qualification: Passes rigorous automotive stress tests (humidity, mechanical shock, solder heat) for zero-defect manufacturing targets.
- ±10% Tolerance: Offers a practical balance between precision and cost, avoiding over-specification while providing dependable filtering in general-purpose automotive circuits.
- Ceramic Dielectric: Delivers low ESR and stable frequency response, minimizing noise coupling in high-speed switching environments such as DC-DC converters.
Frequently Asked Questions
- Q: What makes GCJ188R91E334KA01D different from a standard MLCC?
A: This part is AEC-Q200 qualified, meaning it has undergone additional reliability screening for thermal shock, vibration, and moisture resistance – a requirement for automotive-grade applications that commercial MLCCs do not guarantee. - Q: Is GCJ188R91E334KA01D 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, including fast prototyping supply and flexibility for engineering samples at SZYY.
