(1) Insert capacitance tolerance K for ±10% or M for ±20%.
These components are also available with SnPb plated nickel barrier terminations as a option.
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 500 megohm microfarads or
10GΩ, whichever of the two is smaller.
• Capacitance and Dissipation Factor (DF) measured at the following conditions. 1 kHz and 1 Vrms.
DF Limits for 50V product is 2.5% and for 25V product is 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 resistance to leaching.
Marking
These chips will be supplied unmarked. However, marking is available as an extra cost option.
Qualification/Certification
AEC-Q200 Rev. C - Automotive
RoHS 5 - SnPb termination
RoHS 6 - 100% tin termination
In general, the information in the KEMET Surface Mount catalog F3102 applies to these capacitors. The
