Z5U Dielectric, 50 – 100 VDC (Commercial Grade)
Overview
KEMET’s Z5U dielectric features an 85°C maximum
operating temperature and is considered “general-purpose.”
The Electronics Components, Assemblies & Materials
Association (EIA) characterizes Z5U dielectric as a Class III
material. Components of this classication are xed, ceramic
dielectric capacitors suited for bypass and decoupling or other
Benets
• +10°C to +85°C operating temperature range
• Lead (Pb)-Free, RoHS and REACH compliant
• EIA 0805, 1206, 1210, 1812, 1825, and 2225 case sizes
• DC voltage ratings of 50 and 100 V
• Capacitance offerings ranging from 6,800 pF to 2.2 μF
• Available capacitance tolerances of ±20% and +80%/-20%
• 100% pure matte tin-plated termination nish allowing for
excellent solderability
applications in which dielectric losses, high insulation resistance
and capacitance stability are not of major importance. Z5U exhibits
a predictable change in capacitance with respect to time and
voltage and displays wide variations in capacitance with reference
to ambient temperature. Capacitance change is limited to +22%,
−56% from +10°C to +85°C.
Applications
Typical applications include limited temperature, decoupling and
bypass.

The terms "Marked" and "Unmarked" pertain to laser marking option of capacitors. All packaging options labeled as "Unmarked" will contain capacitors that have
not been laser marked. Please contact KEMET if you require a laser marked option. For more information see "Capacitor Marking".

The 2 mm pitch option allows for double the packaging quantity of capacitors on a given reel size. This option is limited to EIA 0603 (1608 metric) case size
devices. For more information regarding 2 mm pitch option see "Tape & Reel Packaging Information".
Commercial Grade products are subject to internal qualication. Details regarding test methods and conditions are referenced in
Table 4, Performance & Reliability.
Environmental Compliance
Lead (Pb)-Free, RoHS, and REACH compliant without exemptions.

DWV is the voltage a capacitor can withstand (survive) for a short period of time. It exceeds the nominal and continuous working voltage of the capacitor.

Capacitance and dissipation factor (DF) measured under the following conditions:
1kHz ± 50Hz and 1.0 ± 0.2 Vrms if capacitance ≤10µF
120Hz ± 10Hz and 0.5 ± 0.1 Vrms if capacitance >10µF

To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 & Agilent E4980 have a feature known as
Automatic Level Control (ALC). The ALC feature should be switched to "ON".

The "Packaging C-Spec" is a 4 to 8 digit code which identies the packaging type and/or product grade. When ordering, the proper code must be included in the 15th
through 22nd character positions of the ordering code. See "Ordering Information" section of this document for further details. Commercial Grade product ordered without
a packaging C-Spec will default to our standard "Bulk Bag" packaging. Contact KEMET if you require a bulk bag packaging option for Automotive Grade products.

A packaging C-Spec (see note 1 above) is not required for "Bulk Bag" packaging (excluding Anti-Static Bulk Bag and Automotive Grade products). The 15th through
22nd character positions of the ordering code should be left blank. All product ordered without a packaging C-Spec will default to out standard "Bulk Bag" packaging.
Only for capacitance values ≥ 22 µF
Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reow solder
processes. KEMET only recommends wave soldering of EIA 0603, 0805, and 1206 case sizes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reow solder processes.
Density Level C: For high component density product applications. Before adapting the minimum land pattern variations the user should perform qualication
testing based on the conditions outlined in IPC Standard 7351 (IPC –7351).

• All other EIA case sizes are limited to solder reow only
Recommended Reow Soldering Prole:
KEMET’s families of surface mount multilayer ceramic capacitors (SMD MLCCs) are compatible with wave (single or dual), convection,
IR or vapor phase reow techniques. Preheating of these components is recommended to avoid extreme thermal stress. KEMET’s
recommended prole conditions for convection and IR reow reect the prole conditions of the IPC/J-STD-020 standard for moisture
sensitivity testing. These devices can safely withstand a maximum of three reow passes at these conditions.

Storage and Handling
Ceramic chip capacitors should be stored in normal working environments. While the chips themselves are quite robust in other
environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term
storage. In addition, packaging materials will be degraded by high temperature– reels may soften or warp and tape peel force may
increase. KEMET recommends that maximum storage temperature not exceed 40ºC and maximum storage humidity not exceed 70%
relative humidity. Temperature uctuations should be minimized to avoid condensation on the parts and atmospheres should be free of
chlorine and sulfur bearing compounds. For optimized solderability chip stock should be used promptly, preferably within 1.5 years of
receipt.
These surface mount multilayer ceramic capacitors are
normally supplied unmarked. If required, they can be marked
as an extra cost option. Marking is available on most KEMET
devices but must be requested using the correct ordering
code identi er(s). If this option is requested, two sides of the
ceramic body will be laser marked with a “K” to identify KEMET,
followed by two characters (per EIA–198 - see table below) to
identify the capacitance value. EIA 0603 case size devices are
limited to the “K” character only.
Laser marking option is not available on:
• C0G, Ultra Stable X8R and Y5V dielectric devices
• EIA 0402 case size devices
• EIA 0603 case size devices with Flexible Termination option.
• KPS Commercial and Automotive Grade stacked devices.
• X7R dielectric products in capacitance values outlined below

Marking appears in legible contrast. Illustrated below is an
example of an MLCC with laser marking of “KA8”, which
designates a KEMET device with rated capacitance of 100 µF.
Orientation of marking is vendor optional.
KEMET offers multilayer ceramic chip capacitors packaged in 8, 12 and 16 mm tape on 7" and 13" reels in accordance with EIA
