(1) Insert capacitance tolerance K for ±10% or M for ±20%.
These components are also available with SnPb plated nickel barrier termination as an 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 3.5% for 25V product.
Soldering Process
These components are suitable for reflow soldering only. 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
