Overview
The Coilcraft 1206USB-672MLC is a surface-mount common mode choke designed for high-speed differential signal lines. It features an inductance of 412 nH and a DC resistance of 0.34 Ohms. The component provides a common mode impedance of 1.67 kOhms at 100 MHz with a rated current capacity of 500 mA. Housed in a compact 1206 package, it is engineered to suppress electromagnetic interference in USB 2.0 applications.
Feature Summary
- Eliminates common mode noise in high-speed differential signal transmission
- Optimized for USB 2.0 interface protection
- Compact surface-mount design for space-constrained layouts
Applications
- USB 2.0 data line filtering
- High-speed differential signal processing
- Electromagnetic interference suppression in portable electronics
Procurement Notes
Verify the specific suffix (e.g., MLB vs MLC) against the manufacturer datasheet to confirm packaging and tolerance specifications. Confirm availability status as supply may be limited or subject to factory order constraints. Ensure the selected variant matches the required impedance and current ratings for the target circuit design.
Selection Notes
Select this component when designing circuits requiring effective common mode noise reduction for USB 2.0 interfaces. Consider the 412 nH inductance value for compatibility with standard USB signaling frequencies. Evaluate the 500 mA current rating against the maximum operational load of the connected device to ensure reliable performance without saturation.
Part Context
This part belongs to the 1206USB series from Coilcraft, which specializes in common mode chokes for USB applications. The series offers various inductance values tailored for different speed standards, including USB 2.0 and higher speeds. These components are widely used in consumer electronics and computing hardware to maintain signal integrity.
Replacement Considerations
Check for compatible parts within the same 1206USB series, such as variants with different inductance values if system requirements change. Verify that any substitute maintains the 1206 footprint and meets the 500 mA current handling capability.
