What is GCM155R71H681KA37J MLCC?
The GCM155R71H681KA37J is a SMD Capacitor manufactured by Murata. Key specs include 680PF capacitance, 50V rating, X7R dielectric, and ±10% tolerance. RoHS compliant, it is engineered for stable decoupling and filtering in space-limited designs.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power rail decoupling for IoT modules: The 50V rating provides generous headroom for 3.3V or 5V lines, while the 0402 package saves board space in compact wireless designs.
- High-frequency noise suppression in RF chains: X7R dielectric stability plus the small footprint minimize parasitic effects, making it suitable for filter networks in transceiver stages.
- Timing and coupling circuits in portables: ±10% tolerance ensures predictable performance within tight design margins, and the 680PF value supports standard RC time constants.
Key Features & Advantages
- 50V DC voltage rating: Offers extra safety margin over lower-voltage parts, enabling use across both low and intermediate voltage domains.
- X7R temperature characteristic: Capacitance varies within ±15% from -55°C to +125°C, delivering reliable performance under thermal stress.
- 0402 miniature size: Occupies minimal PCB area, facilitating high-density assembly and miniaturized end-product form factors.
Frequently Asked Questions
- Q: What makes GCM155R71H681KA37J different from a standard MLCC?
A: Its combination of a 50V rating in a tiny 0402 body gives higher voltage headroom than typical 16V or 25V parts of the same footprint, allowing more design flexibility. - Q: Is GCM155R71H681KA37J 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 and quick-turnaround sampling.
