Electrical Parameters

As detailed in the KEMET Surface Mount Catalog F3102 for X7R, with the following specific requirements based on room temperature (25°C) parameters:

? Operating Range: -55°C to +125°C, with no-bias capacitance shift limited to the ± 15% over that range. ? Insulating Resistance (IR) measured after 2 minutes at rated voltage @25°C: Limit is 500 megohm-

microfarads or 10,000M ?

, whichever of the two is smaller.

? Capacitance and Dissipation Factor (DF) are measured under the following conditions:

1kHz and 1 Vrms if capacitance * 10μF 120Hz and 0.5 Vrms if capacitance $ 10μF ? DF limits:

50 -200 Volts ü 2.5% 16 -25 Volts ü 3.5% 6.3 / 10 Volts ü 5.0%

Soldering Process

All parts incorporate the standard KEMET barrier layer of pure nickel, with an ove rplate of pure tin to provide excellent solderability as well as resistance to leaching. The recommended mounting techniques are as follows: ? 0402 / 1210 case size s ü Solder Reflow

? 0603 / 0805 / 1206 case sizes ü Solder Wave / Solder Reflow

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 provided in the KEMET Surface Mount catalog F3102 applies to these capacitors. The Information in this bulletin supplements that in the catalog
