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."

1、引言 汽车污染是当前人们最为关心和急需解决的重要课题之一。作为汽车排气污染物的检测的重要方法,简易瞬态工况法（VMAS法，IG法）可以统计排放总质量，监控车辆的真实排放情况，设备成本不高，测量比较准确，与新车认证检测结果具有相关性，可以检测NO相关因子等一系列优点，成为人们研究的热点。VMAS（Vehicle Mass Analysis System）检测方法在美国和欧洲都有很好的应用基础，...[详细]
三星刚出的旗舰新机Galaxy S III固然不错，但是高昂的价格不是每个人都能承受的起。昨天我们报道了一部山寨版的i9300，而现在该机价格和具体配置已经全部出炉。 这款山寨的Galaxy S III名叫HDC Galaxy S3，其外形甚至UI界面都与原型机异常相似。该机的三围为138×70×9.2mm，配备了一块4.7寸触摸屏，分辨率只有800×480像素。
该机还搭载了...[详细]
