Additional Details

The PA4390.101HLT has a common mode impedance of approximately 90 ohms at 100 MHz. The differential mode impedance is typically very low. It is designed for surface mount assembly. The operating temperature range is typically -40°C to +125°C. This common mode choke is constructed with a ferrite core and wound with enameled copper wire. It provides effective common mode noise suppression while minimizing the impact on the desired signal. The compact size and surface mountable design make it easy to integrate into various electronic circuits.
