Surface Mount Tip & Ring Ceramic Chip Capacitors
KEMET鈥檚 250 VDC or Tip & Ring MLCC capacitors are designed and rated for telecommunication ringer cir-
cuits where the capacitor is used to block -48 to -52 Volt DC of line voltage and pass a 16-25 Hz AC signal pulse
of 70 Vrms to 90 Vrms. The surface mount ceramic capacitors are excellent replacements for high voltage leaded
film devices. The smaller SMT footprints save valuable board space which is critical when creating new designs,
and the capacitors are able to withstand today鈥檚 higher lead-free reflow processing temperatures. The ceramic
MLCC have excellent high frequency filtering characteristics, low ESR, and high temperature reflow capabilities.
KEMET Tip and Ring capacitors are available in standard EIA case sizes and standard capacitance values from
0.001渭F to 1.2渭F. The capacitors have pure tin (100% Matte Sn) plated terminations and are 100% lead free which
is ideal for new environmentally demanding designs.
