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. Please contact KEMET if you require a laser marked option. For more information see "Capacitor Marking".
2
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".
Applications
Typical applications include telecommunication ringing circuits, switch mode power supply snubber circuits, high voltage DC blocking and
high voltage coupling. Markets include telephone lines, analog and digital modems, facsimile machines, wireless base stations, cable and
digital video recording set-top boxes, satellite dishes, high voltage power supply, DC/DC converters, and Ethernet, POS and ATM hardware.
Qualification/Certification
Commercial Grade products are subject to internal qualification. Details regarding test methods and conditions are referenced in
Table 4, Performance & Reliability.
Environmental Compliance
Lead (Pb)-Free, RoHS, and REACH compliant without exemptions (excluding SnPb termination finish option).
(5 ±1 seconds and charge/discharge not exceeding 50 mA)
5% (6.3 and 10 V), 3.5% (16 and 25 V) and 2.5% (50 to 250 V)
See Insulation Resistance Limit Table
(Rated voltage applied for 120 ±5 seconds @ 25°C)
Parameters/Characteristics
Regarding aging rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.
To 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 kHz ±50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 µF
120 Hz ±10 Hz and 0.5 ±0.1 Vrms if capacitance >10 µF
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."
