Overview
The AOZ8170DT is an RC (Pi) EMI filter manufactured by Alpha & Omega Semiconductor Inc. It functions as a second-order low-pass filter with eight channels, designed to mitigate electromagnetic and radio frequency interference on signal lines. The component features a resistance of 100 Ohms and capacitance of 8pF per channel, supporting a maximum current of 20 mA. It operates with a cutoff frequency of 220 MHz and provides -20dB attenuation at 1 GHz. The device is housed in a 16-UFDFN exposed pad package.
Feature Summary
- Integrates eight independent filtering channels within a single compact surface-mount package
- Utilizes RC Pi topology to effectively suppress high-frequency noise and interference
- Optimized for maintaining signal integrity in mobile device applications
Applications
- Mobile phone signal line filtering
- General electronic equipment requiring EMI/RFI suppression
- High-speed data interface protection
Procurement Notes
Verify the specific manufacturer documentation for the AOZ8170DT to confirm current production status and compliance certifications such as RoHS or REACH. Ensure that the 16-UFDFN package dimensions and thermal requirements align with your PCB layout constraints before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits that require multi-channel EMI suppression in space-constrained environments. The 100 Ohm resistance and 8pF capacitance values are suitable for standard signal lines where minimal insertion loss is required while maintaining effective high-frequency attenuation up to 1 GHz.
Part Context
This component belongs to the EMI/RFI filters category from Alpha & Omega Semiconductor Inc., specifically utilizing RC network technology. It is distinct from discrete passive components as it integrates multiple filtered paths into one unit, simplifying board assembly and reducing the footprint compared to using individual resistors and capacitors for each channel.
Replacement Considerations
Public confirmed substitute part numbers were not identified in the provided source material. Verify compatibility with alternative multi-channel EMI filters based on matching electrical parameters and package dimensions.
