✔ RoHS Compliant  /  ✔ 0805 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Automotive ECUs & ADAS Modules: With 35V rating and X8L dielectric stable up to 150°C, this capacitor reliably filters supply noise in under-hood and transmission control units.
• Industrial DC-DC Converters: The 4.7µF capacitance in a compact 0805 case enables effective input/output smoothing for 24V rail designs where board space is constrained.
• High-Temperature IoT Gateways: The ±10% tolerance ensures consistent bypass performance across thermal cycles in outdoor or engine-adjacent wireless communication nodes.

Key Features & Advantages

• X8L Dielectric: Guarantees stable capacitance over a -55°C to +150°C range, surpassing standard X7R for extreme-temperature designs.
• 35V Rated Voltage: Provides robust margin for 12V-24V power rails, reducing derating concerns and improving long-term reliability.
• 0805 Footprint: Balances capacitance density with ease of assembly, compatible with automated pick-and-place and reflow processes.

Frequently Asked Questions

1. Q: What makes GCM21BL8EG475KE08L different from a standard X7R capacitor?
   A: Its X8L dielectric extends operational temperature to +150°C, making it suitable for automotive and industrial applications where X7R would degrade capacitance above +125°C.
2. Q: Is GCM21BL8EG475KE08L 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 and flexible quantity requests.
