What is GCJ21BR71H105KA01K MLCC?
The GCJ21BR71H105KA01K is a SMD capacitor manufactured by Murata（村田）. Key specs include 1μF capacitance, 50V DC rating, X7R dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable filtering and decoupling in space-constrained circuits.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 1μF capacitance combined with 50V rating provides effective ripple suppression in power modules operating at intermediate bus voltages.
- Automotive ECU Decoupling: With X7R temperature stability and Murata’s robust construction, this capacitor reliably bypasses noise on 48V vehicle electrical systems.
- Industrial Sensor Interface: The compact 0805 package allows dense PCB layouts while the ±10% tolerance ensures consistent timing in ADC reference circuits.
Key Features & Advantages
- High Voltage Rating (50V): Offers generous headroom above typical 3.3V/5V rails, reducing derating concerns and improving long-term reliability.
- X7R Dielectric: Maintains capacitance stability across -55°C to +125°C, critical for automotive and industrial temperature extremes.
- 0805 Footprint: Balances ease of hand-assembly with moderate capacitance density, ideal for prototypes and medium-volume production.
Frequently Asked Questions
- Q: What makes GCJ21BR71H105KA01K different from a standard MLCC?
A: This Murata part uses a reinforced internal electrode design for improved bending crack resistance, making it better suited for automotive and harsh-environment applications compared to general-purpose 0805 capacitors. - Q: Is GCJ21BR71H105KA01K 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 small-batch flexibility for pre-production runs.
