Surface Mount Ceramic Chip Capacitors – Ultra Stable X8R Dielectric
KEMET’s Ultra Stable X8R Dielectric features a 150°C maximum operating temperature, offering the latest in high temperature di-
electric technology and therefore a reliable choice for extreme temperature applications. It offers the same temperature capability
as conventional X8R, but without the capacitance loss due to applied DC voltage. Ultra Stable X8R exhibits no capacitance loss
and is a suitable replacement for higher capacitance and larger footprint devices that fail to offer capacitance stability. Product ap-
plications include harsh environments such as Down Hole (Oil Exploration), Automotive (Under Hood), Military and Aerospace.
Six standard package options are available which include EIA 0402, 0603, 0805, 1206, 1210, and 1812 case sizes. Devices are
available in dc voltage ratings of 25V, 50V and 100V, with capacitance offerings ranging from 10pF to 0.22μF. Capacitance toler-
ances offerings include ±1%, ±2%, ±5%, ±10% and ±20%, with capacitance shift limited to ±15% from -55°C to +150°C.
All parts are environmentally friendly, in compliance with RoHS legislation (RoHS 6/6) and are being offered in both commercial
and automotive grades with 100% pure matte tin-plated terminations that allow for excellent solderability. A Sn/Pb termination
option is also available upon request.

Soldering Process
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. The recommended techniques are as follows:
• 0402 and
≥1210
Case Sizes - Solder Reflow Only
• 0603/0805/1206 Case Sizes - 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 in the KEMET Surface Mount catalog F3102 applies to these capacitors. The information in this bulletin
supplements that in the catalog.
