... Pseudo inductance for telephones BA8201 / BA8201F The BA8201 and BA8201F are ICs with a choke coil action, capable of extracting the DC current from a telephone line while maintaining a high inductance on the telephone line side. This eliminates the need for a choke coil, and facilitates use of the telephone set line in a variety of applications. ...
