Description:Highly Integrated Common Mode Filter (CMF) with ESD Protection provides protection and EMI Reduction for systems using high speed Serial Data Lines with cost and space savings over Discrete Solutions; Large Differential Mode Bandwidth with Cutoff Frequency > 2 GHz; High Common Mode Stop Band Attenuation: >25 dB at 700 MHz, >30 dB at 800 MHz Typical; Provides ESD Protection to IEC61000-4-2 Level 4, 12 kV Contact Discharge; Low Channel Input Capacitance Provides Superior Impedance Matching
A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern under the device.
Implement a robust thermal management system, including a heat sink, thermal interface material, and a cooling fan if necessary. Monitor junction temperature and adjust the system design accordingly.
Monitor the device's junction temperature, output voltage, and current. Implement over-temperature protection, over-voltage protection, and over-current protection to prevent damage.
Consult the application note and reference design provided by onsemi. Optimize the PCB layout, component selection, and thermal management system for your specific use case.
Use a reflow soldering process with a peak temperature of 260°C. Ensure a clean and dry PCB, and follow the recommended solder paste and stencil design guidelines.
