✔ RoHS Compliant  /  ✔ 0603  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Automotive ECU modules: The X8R dielectric ensures stable capacitance up to 150°C, perfect for under-hood electronics.
• Industrial power supply decoupling: 0.39µF at 25V effectively filters noise in DC-DC converters while withstanding harsh thermal cycles.
• High-reliability sensor circuits: ±10% tolerance and Murata’s proven quality make it suitable for precision sensing near heat sources.

Key Features & Advantages

• X8R Dielectric: Offers superior temperature stability (-55°C to +150°C) compared to standard X7R, extending application range.
• 0603 Compact Footprint: Saves board space while delivering 0.39µF, ideal for dense automotive and industrial layouts.
• High Voltage Rating: 25V provides ample margin for 5V, 12V, and 24V supply rails, reducing derating concerns.

Frequently Asked Questions

1. Q: What makes GCJ188R91E394KA01D different from a standard X7R MLCC?
   A: It uses X8R dielectric, which maintains capacitance and reliability up to 150°C, whereas X7R is limited to 125°C. This makes it essential for high-temperature applications.
2. Q: Is GCJ188R91E394KA01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. 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 with flexible quantities.
