Overview
The SDCW1210U-2-900TF is a two-line common mode choke manufactured by Shenzhen Sunlord Electronics Co., Ltd. Designed for surface mount applications, this component features an impedance of 90 Ohms at 100 MHz and supports a current rating of 280 mA. The device exhibits a direct current resistance (DCR) of 500 mOhm. It utilizes a compact SMD-6P package with dimensions of 1.2x1 mm, suitable for space-constrained circuit designs requiring effective noise suppression.
Feature Summary
- Provides common mode noise filtering for differential signal lines
- Utilizes a compact surface mount footprint for automated assembly
- Engineered for low insertion loss in high-frequency environments
Applications
- High-speed data interface protection
- USB port noise suppression
- HDMI line interference reduction
Procurement Notes
Verify the complete part number including suffixes to ensure correct impedance and tolerance specifications. Confirm package dimensions against PCB footprints prior to ordering. Request manufacturer datasheets for detailed electrical characteristics and reliability testing data. Validate supplier authorization status to guarantee component authenticity and traceability throughout the supply chain.
Selection Notes
Evaluate the 90 Ohm impedance value against target frequency requirements for effective attenuation. Ensure the 280 mA current rating exceeds maximum operational load to prevent saturation. Check the 500 mOhm DCR impact on signal integrity and power efficiency. Confirm the SMD-6P package size fits within available board real estate constraints.
Part Context
This component belongs to Sunlord's chip common mode choke product line. The series focuses on providing electromagnetic interference suppression for electronic devices. These components are integral to maintaining signal quality in modern digital systems where noise immunity is critical for reliable operation.
Replacement Considerations
Consult official substitution lists for compatible alternatives. Verify that any substitute matches the 90 Ohm impedance at 100 MHz and 280 mA current rating. Ensure physical compatibility with the SMD-6P 1.2x1 mm package. Confirm equivalent electrical performance before implementation.
