Overview
The SDCW1210H-2-350TF is a surface mount common mode choke manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features an impedance of 35 Ohms at 100 MHz with a tolerance of ±25%. The component has a DC resistance (DCR) of 320 mOhm and supports a current rating of 320 mA. It utilizes a metal ferrite core and operates within a temperature range of -40°C to +125°C, including self-heating effects.
Feature Summary
- Utilizes a metal ferrite core for effective noise suppression
- Designed for surface mount assembly in compact layouts
- Provides common mode interference filtering for signal lines
Applications
- High-speed data handling circuits
- FPGA interface protection
- Signal line noise suppression
Procurement Notes
Verify the specific ordering suffix and packaging configuration against official Sunlord documentation before procurement. Confirm that the tape and reel format matches your automated assembly equipment requirements. Ensure the requested quantity aligns with standard manufacturing lot sizes to avoid potential supply chain delays or non-standard handling procedures during production integration.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation at high frequencies. The 35 Ohm impedance at 100 MHz makes it suitable for digital signal integrity applications. Consider the 320 mA current rating to ensure the component does not saturate under normal operating conditions. Verify thermal performance within the specified -40°C to +125°C range for the intended environment.
Part Context
This part belongs to the SDCW-H series of common mode chokes from Sunlord. It is designed for surface mount technology (SMT) applications. The package footprint corresponds to the 1210 metric size, utilizing a four-pad configuration for secure board attachment and reliable electrical connection during soldering processes.
Replacement Considerations
Consult official Sunlord documentation for verified substitute part numbers within the SDCW series. Ensure any replacement maintains equivalent impedance characteristics and current ratings to preserve circuit functionality and signal integrity without modifying the existing design layout.
