Overview
The SDCW2012-2-371TF is a two-line common mode choke manufactured by Shenzhen Sunlord Electronics Co., Ltd. in a surface-mount package with dimensions of 2.0mm x 1.2mm. It exhibits an impedance of 370 Ohms at 100 MHz and supports a rated current of 280mA. The component features a DC resistance (DCR) of 450mOhm and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Utilizes a wound structure for effective high-frequency common mode noise suppression
- Features a low-profile design suitable for space-constrained surface mount applications
Applications
- USB 2.0 interfaces for PC peripherals and digital AV equipment
- LVDS lines for LCD displays in laptops
- Audio signal lines
Procurement Notes
Verify the specific part number against official Sunlord documentation to confirm impedance tolerance and current ratings. Ensure the surface mount footprint matches the 2012 metric package dimensions. Confirm moisture sensitivity level and storage conditions prior to assembly to maintain component integrity during soldering processes.
Selection Notes
Select this component when designing circuits requiring common mode noise filtering for high-speed data lines such as USB or LVDS. Consider the 280mA current rating and 450mOhm DCR to ensure compatibility with power delivery requirements. Evaluate the 370 Ohm impedance at 100 MHz against the target noise frequency spectrum for optimal attenuation performance.
Part Context
This component belongs to the SDCW series of common mode chokes from Shenzhen Sunlord Electronics. The series offers various impedance options ranging from 67 Ohms to 180 Ohms for different noise levels, though this specific model provides 370 Ohms. The manufacturer specializes in magnetic devices for communication, consumer electronics, and automotive sectors.
Replacement Considerations
Compatible substitutes include other 0805 package common mode chokes with similar electrical characteristics. Verify that alternative parts match the 280mA current rating and comparable impedance values to ensure circuit functionality remains unchanged.
