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

Typical Applications & Why This Part Fits

• Automotive Engine Control Units (ECU): The X8R dielectric ensures stable capacitance over a wide temperature range up to 150°C, meeting stringent under-hood reliability requirements.
• DC-DC Converter Output Filtering: With its 0.022µF value and 50V rating, this part provides effective high-frequency decoupling in power supply modules without exceeding voltage margins.
• Infotainment & Telematics: The compact 0603 package allows dense PCB layout, while the ±10% tolerance ensures consistent performance in timing and filter circuits.

Key Features & Advantages

• High-Temperature X8R Dielectric: Operates reliably from -55°C to +150°C, making it ideal for harsh environments like automotive and industrial.
• 50V Voltage Rating: Provides ample safety margin in 12V, 24V, and even 48V systems, reducing derating concerns.
• Murata Manufacturing Quality: Industry-leading production control ensures low failure rates and stable electrical characteristics over lifetime.

Frequently Asked Questions

1. Q: What makes GCM188R91H223KA37D different from a standard X7R capacitor?
   A: The X8R dielectric offers better capacitance stability up to 150°C versus X7R’s 125°C limit, critical for high-temperature designs.
2. Q: Is GCM188R91H223KA37D 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 full BOM kitting at SZYY, including fast prototyping supply for quick-turn evaluation of this part.
