Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)

U2J Dielectric, 10 – 50 VDC

(Commercial & Automotive Grade)

Overview

KEMET U2J dielectric features a maximum operating

temperature of 125°C and is considered stable. The

Electronics Industries Alliance (EIA) characterizes U2J

dielectric as a Class I material. Components of this

classification are temperature compensating and are

suited for resonant circuit applications or those where Q

and stability of capacitance characteristics are required.

U2J is an extremely stable dielectric material that exhibits

a negligible shift in capacitance with respect to voltage

and boasts a predictable and linear change in capacitance

with reference to ambient temperature with no aging

effect. In addition, U2J dielectric extends the available

capacitance range of Class I MLCCs to achieve values

previously only available using Class II dielectric materials

like X7R, X5R, Y5V and Z5U.

U2J is not sensitive to DC Bias as compared to Class

II dielectric materials and retains over 99% of nominal

capacitance at full rated voltage. KEMET automotive grade

capacitors meet the demanding Automotive Electronics

Council's AEC–Q200 qualification requirements.

Capacitance change is limited to −750 ±120 ppm/°C from

−55°C to +125°C. These devices are lead (Pb)-free, RoHS

and REACH compliant without exception and are capable

of withstanding multiple passes through a lead (Pb)-free

solder reflow profile.

Default packaging is "Bulk Bag". An ordering code C-Spec is not required for "Bulk Bag" packaging.

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. The option to laser mark is not available on these devices. 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."

Reeling tape options (paper or plastic) are dependent on capacitor case size (l" x w") and thickness dimensions. See "Chip Thickness/Tape & Reel

Packaging Quantities" and "Tape & Reel Packaging Information."

For additional information regarding "AUTO" C-Spec options, see "Automotive C-Spec Information."

All automotive packaging C-Specs listed exclude the option to laser mark components. The option to laser mark is not available on these devices.

Commercial grade products are subject to internal qualification. Details regarding test methods and conditions are

referenced in Table 4, Performance & Reliability.

Automotive grade products meet or exceed the requirements outlined by the Automotive Electronics Council. Details

regarding test methods and conditions are referenced in the document AEC–Q200, Stress Test Qualification for Passive

Components. For additional information regarding the Automotive Electronics Council and AEC–Q200, please visit their

website at www.aecouncil.com.

Automotive C-Spec Information

The KEMET automotive grade products meet or exceed the requirements outlined by the Automotive Electronics Council.

Details regarding test methods and conditions are referenced in document AEC–Q200, Stress Test Qualification for Passive

Components. These products are supported by a Product Change Notification (PCN) and Production Part Approval Process

warrant (PPAP).

Automotive products offered through our distribution channel have been assigned an inclusive ordering code C-Spec, “AUTO.”

This C-Spec was developed in order to better serve small and medium-sized companies that prefer an automotive grade

component without the requirement to submit a customer Source Controlled Drawing (SCD) or specification for review by a

KEMET engineering specialist. This C-Spec is therefore not intended for use by KEMET OEM automotive customers and are

not granted the same “privileges” as other automotive C-Specs. Customer PCN approval and PPAP request levels are limited

(see details below.)

Product Change Notification (PCN)

The KEMET Product Change Notification system is used to communicate primarily the following types of changes:

• Product/process changes that affect product form, fit, function, and/or reliability

• Changes in manufacturing site

• Product obsolescence

KEMET assigned C-Specs require the submittal of a customer SCD or customer specification for review. For additional information contact KEMET.

Production Part Approval Process (PPAP)

The purpose of the Production Part Approval Process is:

• To ensure that supplier can meet the manufacturability and quality requirements for the purchased parts.

• To provide the evidence that all customer engineering design records and specification requirements are properly

understood and fulfilled by the manufacturing organization.

• To demonstrate that the established manufacturing process has the potential to produce the part.

Parameters/Characteristics

obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.

Capacitance and dissipation factor (DF) measured under the following conditions:

1 MHz ±100 kHz and 1.0 V

rms

±0.2 V if capacitance ≤ 1,000 pF

1 kHz ±50 Hz and 1.0 V

rms

±0.2 V if capacitance > 1,000 pF

Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known

as Automatic Level Control (ALC). The ALC feature should be switched to "ON."
