FE-CAP
/ X7R Dielectric
Product Description
The FE-CAP is a SMD MLCC utilizing a floating internal electrode design, wherein the electrodes are con-
figured to form multiple capacitors in series within a single MLCC package. This not only yields improved
voltage and ESD performance over standard designs, but also mitigates the risk of low-IR or short-circuit
failures that can occur due to board flex. Combined with the stability of an X7R dielectric, the FE-CAP com-
plements KEMET's Open Mode Devices by providing a fail-safe design optimized for low to mid range
capacitance values.

Electrical Parameters
As detailed in the KEMET Surface Mount Catalog F3102 for X7R, with following specific requirements
based on room temperature (25°C) parameters:
• Operating Range: -55°C to +125°C, with no-bias capacitance shift limited to ± 15% over that range.
• Insulation Resistance (IR) measured after 2 minutes at rated voltage @ 25°C: Limit is 1,000
megohm microfarads or 100 gigohm, whichever is less.
• Capacitance and Dissipation Factor (DF) measured at 1kHz and 1 Vrms.
DF Limits are:
50 - 250 Volts
16 - 25 Volts
2.5%
3.5%
Soldering Process
These components are suitable for reflow and wave soldering. All parts incorporate the standard KEMET
barrier layer of pure nickel, with an overplate of pure tin to provide excellent solderability as well as resist-
ance to leaching.
Marking
These chips will be supplied unmarked. If required, they can be laser-marked as an extra option.
Details on the marking format are included in KEMET Surface Mount catalog F3102.
In general, the information in the KEMET Surface Mount catalog F3102 applies to these
capacitors. The information in this bulletin supplements that in the catalog.
