Surface Mount Tip & Ring Ceramic Chip Capacitors
KEMET’s 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’s 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
0.001μF to 1.2μF. The capacitors have pure tin (100% Matte Sn) plated terminations and are 100% lead free which
is ideal for new environmentally demanding designs.

These chips are supplied unmarked. If required, they can be laser-marked as an extra cost option. Details on the
marking format are included in KEMET Surface Mount Catalog F3102 on page 96.
The 0805 and 1206 sizes are suitable for either reflow or wave soldering. Sizes 1210 and larger should be limited
to reflow soldering only. All sizes incorporate the standard KEMET barrier layer of pure nickel with an overplating
of pure tin for excellent solderability and resistance to leaching of the termination.
KEMET High Voltage Surface Mount MLCC capacitors are available packaged in tape and reel configuration.
