Tip & Ring
Multilayer Ceramic Chip Capacitors
AVX Tip & Ring or ring detector Multilayer Ceramic Chip
Capacitors are designed as a standard telecom filter
to block -48 Volts DC telephone line voltage and pass
subscribers AC signal pulse (16 to 25Hz, 70 to 90Vrms).
The typical ringing signal is seen on figure on page 132. The
ringer capacitors replace large leaded film capacitors and
are ideal for telecom/modem applications. Using AVX Tip &
Ring capacitors not only saves valuable real estate on the
board and reduces the weight of overall product, but also
features standard surface mounting capabilities, so critical to
new and compact designs.
The AVX Tip & Ring capacitors are offered in standard
EIA sizes and standard values. They offer excellent high
frequency performance, low ESR and improved temperature
performance over film capacitors.
