AF102 - Dial Tone Reject Filter

The AF102 is a fourth order elliptic highpass filter designed to reject frequencies below 650Hz.

This filter rejects the 350Hz and 440Hz dial tone frequencies present on a telephone line.

The unit is fully tuned and requires no external components - only input, output and power supply connections.
