Surface Mount Ceramic Chip Capacitors – X8L Dielectric
KEMET’s X8L Dielectric offers an operating temperature range from -55°C to +150°C with capacitance shift
limited to ±15% from -55°C to +125°C and +15, -40% from 125°C to 150°C. Product applications include harsh
environments such as Down Hole (Oil Exploration), Automotive (Under Hood), Military and Aerospace.
Five standard package options are available which include EIA 0402, 0603, 0805, 1206, and 1210 case sizes.
Devices are available in dc voltage ratings of 10V, 25V and 50V, with capacitance offerings ranging from 10pF to
0.22μF. Capacitance tolerances offerings include ±5%, ±10% and ±20.
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.
