The Tip & Ring MLCC series are designed specifically for
telecom ringer circuit applications where it is necessary to
provide a block of the line voltage (typically -48 VDC) while
passing the AC ringing voltage. These compact ceramic SMD
chips replace bulky leaded film caps saving board space and
stream-lining the assembly process.
