固体钽电解电容器是1956年由美国贝尔试验室首先研制成功的， 它的性能优异，是所有电容器中体积小而又能达到较大电容量的产品。钽电解电容器外形多种多样，并容易制成适于表面贴装的小型和片型元件，适应了目前电子技术自动化和小型化发展的需要。虽然钽原料稀缺，钽电解电容器价格较昂贵，但由于大量采用高比容钽粉(50K-150kμF.V/g)，加上对电容器制造工艺的改进和完善，钽电解电容器还是得到了迅速的发展，使用范围日益广泛。钽电解电容器不仅在军事通讯、航天等领域广泛使用，而且还在工业控制、数字化音频及影视设备、仪器仪表等产品中大量使用。
目前生产的钽电解电容器主要有烧结型固体、箔形卷绕固体、烧结型液体三种，其中烧结型固体约占生产总量的95％以上,小型片式钽电解电容器已成为市场主流品种。
固体钽电解电容器电气性能优良，频率特性好，工作温度范围宽，可靠性高，而且封装形式多样，容积效率高，具有如下特征：
●钽电解电容器的介电质是在钽阳极体表面生成一层极薄的五氧化二钽膜，介电常数，比容量非常高，适宜小型化。
●钽电解电容器在工作过程中，具有自动修补或隔绝氧化膜疵点的能力，这种独特的自愈性能，使介质氧化膜随时得到加固和恢复其应有的绝缘能力，而不致遭到连续的累积性破坏，保证了其长寿命和高可靠的优势。
●钽电解电容器工作电场强度高于其它类型电容器。
●钽电解电容器具有高电容量，在电源滤波、交流旁路等应用上少有竞争对手。
●具有单向导电性，即有“极性”，应用时应按电源的正、负方向正确连接，电容器的阳极（正极）接电源“+”极，阴极（负极）接电源的“—”极，如果接错，电容器漏电流就会增大，短时间内阳极芯子就会发热，击穿介电质，随即失效。 ●工作电压有上限值，但如果与晶体管、集成电路或电源配合使用，这一点微不足道。
一般认为电解电容器是一种性能优良，使用寿命长的电子元件，它的失效率正常时可达七级，但它总还是符合电子元器件的失效普遍规律，即澡盆形失效曲线，其前期失效可通过生产过程中老炼技术剔除，因此只有随机失效的可能性。而这种失效即有制造材料本身的缺陷，也有制造工艺控制问题，还常常伴随产品在使用过程的不当或超载所致，综合说来大约有三种失效模式即电流型、电压型和发热型。
钽电解电容器具有贮存电荷、进行充放电等性能，主要应用于滤波、旁路、耦合与退耦以及作时间常数元件等。在应用中注意其性能特点，正确使用会有助于充分发挥其功能，其中诸如考虑产品工作环境及其发热温度，采取降额使用等措施，如果使用不当会影响产品的工作寿命。
星日电子主导产品是烧结型固体电解质片式钽电容器，同时生产树脂包封型、金属壳封装型、聚合物型固体电解质钽电容器以及金属壳封装型非固体电解质钽电容器，可提供不同结构、封装形式的耐高温、高电压、大容量、低ESR、小壳号、薄型长寿命、高可靠性系列钽电容器。
钽电解电容器简介
钽电解电容器简介
Solid tantalum electrolytic capacitors first developed successfully at Bell Laboratory,USA in 1956,feature excellent performances，higher capacitance and small size compared with other types of capacitors．Tantalum capacitor is encapsulated in various forms, miniature tantalum chip capacitors are easily fabriated to suit surface mounting applications and meet the demands of development of current electronic automated mounting technology and miniaturization Although lack of tantalum raw materials, tantalum capacitors are more expensive than other dielectrics, but are widely used in more applications and have grown with big strides based on using high capacitance tantalum powder(50K-100KμF.V/g) and continuous improvement of manufacture technology. Tantalum capacitors are widely used not for telecommunication ,aerospace and military applications ,but also for industrial controls digital audio/video equipment instruments and meters．
Tantalum electrolytic capacitors are now available with main three categories of the sintered solid electrolyte, foil wounded solid electrolyte, and sintered wet electrolyte. Among them, the sintered solid capacitors accounts for over 95% of the total production, miniature tantalum chip capacitors are playing a dominant role in the markets.
Solid tantalum capacitors have advantages of excellent electrical performance，wide working temperature range，good volume efficiency and various encapsulation forms，uniquely characterized in：
●Thin tantalum oxide(Ta O) film forms over all the tantalum surfaces, serving as working dielectric of tantalum
25
capacitors;
●The dielectric film has high dielectric constant, “large volume capacitance per unit or specific capacitance, suitable for miniaturization;
●During the operation, tantalum electrolytic capacitors feature self-healing and blocking defects of the tantalum oxide film,strengthening dielectric at any time,recovering thecapability of insulation and preventing from continuougsaccumulative breakdown,The unique performance of self-healing assures its long life and high reliability;．
●Tantalum electrolytic capacitors have high electric field strength compared with any other type of capacitor;
●Tantalum Electrolytic Capacitors have higher capacitance, used for applcations in pow iltering,bypassing,coupling,etc, no competitive counterpart;
●Tantalum electrolytic capacitors have unilateral conductivity or polarity.When using,tantalum capacitor is connected according to "plus and minus"terminals of power supply correspondingly.Wrong connection result in increasing DC leakage thereby heating up in the anode in a short time，breaking down of the dielectric,at the meantime,the capacitor became defected part
●There is an upper limit for working voltage，but it is negligible when using the capacitors together with transistors,rintegrated electric circuit or, power supply.
Eectrolytic capacitor is usually regarded as a kind of electronic component with excellent performance and long working life, its failure rate under normal condition can be up to VII Grade,but still conform to common failure pattern of electronic components that is bathtub-shape failure curve. Failure parts at earlier stage can be eliminated during aging，thus only accidental failure is possible. The failure may result from both defects of raw materials and prolems on process control or improper use or overload of the capacits .peaking,，there are three failure modes:electric current, electric voltage and heating-up modes.
Tantalum electrolytic capacitors also feature storing electric charge charging and discharging etc, mainly used for filtering, storing electricenergy and conversion,siganal bypassing,coupling anddecoupling also used as a time-constant component, etc. The user should pay attention to its performances and use themproperly,thus the functions can be brought into full use When using,．the user should give consideration to such factors as working environmint,heationg temperature and adopt such measures as working environment heating temperature and adopt such measuresn as sing by voltage derating，moreover improper use may have influence on working life of the capacitors.．
Except for sintered solid tantalum chip capacitor as dominant product,Ningxin Xingri Electronics Co., Ltd．also produce radial lead,epoxy-coated solid tantalum electrolytic capacitor, metal-cased solid tantalum electrolytic capacitor metal-cased wet tantalum electrolytic capacitor and polyer solid tantalum chip capacitor. They are available in various constructions disogn ,encapsulate forms and shapes.
