逆向電壓防護 Reverse Voltage Protection
當串聯EDLC迅速放電,容量值低的電容器之上的電壓將潛在地變為負電壓。如之前的解釋,此是
不希望出現的且會縮短EDLC的工作壽命。一種簡單的防護逆向電壓的方法是在電容器上增加一個
二極管。使用適當的額定的限流二極管替代標准的二極管,還可以保護EDLC出現過電壓現象。須
謹慎的是確保二極管能承受電源的峰值電流。
When series connected EDLC are rapidly discharged, the voltage on low capacitance value parts can
potentially become negative. As explained previously, this is not desirable and can reduce the operating life of
the EDLC. One simple way of protecting reverse voltage is to add a diode across the capacitor, configured so
that it is normally reverse bias. By using a suitably rated zener diode in place of a standard diode the EDLC
can also be protected against overvoltage events. Care must be taken to ensure that the diode can withstand
the available peak current from the power source.
焊接信息 Soldering Information
過熱會導致EDLC電性能的退化,漏液或內壓升高。焊接應遵循以下具體指示:
• 不要把EDLC浸入已熔解的焊錫中。
• 只在EDLC導針上粘上焊劑。
• 確保EDLC套管不直接與PCB或其它組件接觸,過高的焊錫溫度會導致套管收縮或破裂。
• 避免EDLC在裸露的電路板之下工作以防止短路發生。
Excessive heat may cause deterioration of the electrical characteristics of the EDLC, electrolyte leakage or an
increase in internal pressure. Follow the specific instructions listed as below:
• Do not dip EDLC body into melted solder.
• Only flux the leads of the EDLC.
• Ensure that there is no direct contact between the sleeve of the EDLC and the PC board or any other
component. Excessive solder temperature may cause sleeve to shrink or crack.
• Avoid exposed circuit board runs under the EDLC to prevent electrical shorts.
手工焊接 Manual Soldering
不可讓EDLC外部套管與焊棒接觸,否則套管會熔化或破裂。焊嘴溫度建議低於350˚C,焊接持續時
間少於4秒鐘。應使烙鐵與EDLC導針直接接觸時間最小化,因為導針的過熱會提高等效串聯電阻值
(ESR)。
Do not touch the EDLC
’
s external sleeve with the soldering rod, or the sleeve will melt or crack. The
recommended temperature of the soldering rod tip is less than 350˚C and the soldering duration should be
less than 4 seconds. Minimize the time that the soldering iron is in direct contact with the terminals of the
EDLC, as excessive heating of the leads may lead to higher equivalent series resistance (ESR).
