Tip & Ring Tin/Lead Termination “B”
Multilayer Ceramic Chip Capacitors
AVX Corporation will support customers for commercial and military Multilayer
Ceramic Capacitors with a termination consisting of 5% minimum lead. This
termination is indicated by the use of a “B” in the 12th position of the AVX
Catalog Part Number. This fulfills AVX’s commitment to providing a full range of
products to our customers. AVX has provided in the following pages, a full range
of values that we are offering in this “B” termination.
AVX “Tip & Ring” or “ring detector” Multilayer Ceramic Chip Capacitors are
designed as a standard telecom filter to block -48 Volts DC telephone line volt-
age and pass subscriber’s AC signal pulse (16 to 25Hz, 70 to 90 VRMS). The
typical ringing signal is seen on figure on page 130. The ringer capacitors
replace large leaded film capacitors and are ideal for telecom/modem applica-
tions. Using AVX “Tip and Ring” capacitors not only saves valuable real estate
on the board and reduces the weight of the 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.
