The AF103 is a fourth order elliptic low pass filter designed to reject frequencies above 1200 Hz and pass signals

below 950 Hz.

This filter is used to separate the low band of frequencies from the high band in a Dual Tone Multi Frequency (DTMF) Touch Tone® receiver.

Fully tuned.
High input impedance.
Low output impedance.
