貼片薄膜電容是貼片電容類(lèi)型當(dāng)中應(yīng)用最為廣泛而且銷(xiāo)量較高的電容產(chǎn)品，具有其它型號(hào)電容所不具備的優(yōu)勢(shì)，對(duì)于采購(gòu)人員來(lái)講，熟知貼片薄膜電容的優(yōu)勢(shì)才能選購(gòu)更適合的電容。
SMD film capacitor is the most widely used and high-sales capacitor among the SMC types. It has the advantages that other types of capacitors do not have. For purchasers, only when they are familiar with the advantages of SMC can they choose more suitable capacitors.
現(xiàn)工業(yè)領(lǐng)域的電力電子對(duì)元器件的選擇有了更高的要求，無(wú)論是電氣特性方面還是環(huán)境的操作條件的要求。電容器也不例外，產(chǎn)品的可靠性越來(lái)越成為關(guān)鍵。在電力電子應(yīng)用中，貼片薄膜電容器比其他電容器更具有優(yōu)勢(shì)。
Nowadays, the power electronics in the industrial field have higher requirements for the selection of components, whether in terms of electrical characteristics or environmental operating conditions. Capacitors are no exception, and the reliability of products is becoming more and more important. In power electronics applications, SMC has more advantages than other capacitors.
貼片薄膜電容以其優(yōu)越的電性能在高壓高頻大功率電力電子設(shè)備中得以廣泛應(yīng)用，特別在DC-LINK這個(gè)應(yīng)用場(chǎng)合，薄膜電容與電解電容相比較具有高紋波電流承受能力、耐高壓、低ESR和ESL、長(zhǎng)壽命、(干式防爆)、無(wú)極性和高頻特性好等優(yōu)越的電氣性能，在高壓大功率電力電子設(shè)備中DC-LINK應(yīng)用薄膜電容替代電解電容是一種趨勢(shì)。
SMD film capacitors are widely used in high-voltage, high-frequency and high-power power electronic equipment due to their superior electrical properties. Especially in DC-link applications, thin-film capacitors have superior electrical properties, such as high ripple current bearing capacity, high-voltage resistance, low ESR and ESL, long-life, (dry explosion-proof), good polarity and high-frequency characteristics, etc It is a trend for DC-link to replace electrolytic capacitor with thin film capacitor in force electronic equipment.
貼片薄膜電容能夠承受高有效電流的能力，最高可達(dá)1Arms/μF。
The SMC can withstand high effective current up to 1 RMS / μ F.
貼片薄膜電容還具有抗浪涌能力強(qiáng)，能承受2UnV的浪涌電壓。此外對(duì)于高峰值的電流承受能力，可達(dá)到100V/μs, ESL電感量小，充放電速度快。
SMC also has strong anti surge ability and can withstand 2un V surge voltage. In addition, the current withstand capacity of the peak value can reach 100V / μ s, the inductance of ESL is small and the charging and discharging speed is fast.
對(duì)于貼片薄膜電容來(lái)說(shuō)，除了以上的優(yōu)勢(shì)，還具有耐壓高，無(wú)極性的優(yōu)勢(shì)，而耐壓值能承受1.5倍于額定電壓的過(guò)壓。無(wú)極性則是能夠長(zhǎng)期承受反向脈沖電壓。
For SMD film capacitor, in addition to the above advantages, it also has the advantages of high withstand voltage and non polarity, and the withstand voltage value can withstand over-voltage of 1.5 times of the rated voltage. Non polarity is able to withstand reverse pulse voltage for a long time.
從專業(yè)的角度來(lái)說(shuō)，貼片薄膜電容不僅介質(zhì)損耗小，產(chǎn)品內(nèi)部溫升低，溫度特性好。而且還具有壽命長(zhǎng)的優(yōu)勢(shì)，從環(huán)保角度來(lái)說(shuō)，則是沒(méi)有酸污染，可以實(shí)現(xiàn)長(zhǎng)時(shí)間的存儲(chǔ)。
From a professional point of view, SMC not only has small dielectric loss, but also has low temperature rise and good temperature characteristics. Moreover, it has the advantage of long service life. From the perspective of environmental protection, it has no acid pollution and can realize long-term storage.
