Capacitor tantalum hmoov thiab kev siv

Tantalum electrolytic capacitor yog tantalum raws li cov hlau anode los ntawm anodic oxidation nyob rau hauv tantalum nto ncaj qha generated dielectric (nyob rau hauv cov kev taw qhia ntawm hluav taws xob rwb thaiv tsev, rov qab voltage yog conductive) oxide zaj duab xis ntawm hluav taws xob khoom. Qhov sib txawv tseem ceeb tshaj plaws ntawm tantalum capacitors thiab lwm hom capacitors yog qhov zoo ntawm tantalum oxide dielectric zaj duab xis, uas muaj lub siab dielectric tas li thiab tawg voltage. Qhov siab dua qhov purity ntawm tantalum hmoov, qhov siab dua qhov tawg voltage ntawm anode zaj duab xis ntawm tantalum capacitor. Tantalum hmoov muaj qhov tshwj xeeb saum npoo av, uas tseem nyob siab txawm tias tom qab nias thiab sintering vim nws cov qauv pore tshwj xeeb, ua rau muaj qhov tshwj xeeb (hluav taws xob) capacitance ntawm lub capacitor. Tantalum hmoov rau capacitors ntawm kev khiav hauj lwm voltages qis dua 25 volts yog feem ntau hu ua siab tshwj xeeb capacitance tantalum hmoov vim hais tias ntawm nws cov high tshwj xeeb capacitance, tantalum hmoov rau capacitors nrog kev khiav hauj lwm voltages ntawm 25 volts los yog ntau tshaj muaj nruab nrab voltage (35 mus rau 40 volts) thiab high voltage. (50 mus rau 63 volts) tantalum hmoov. High-capacitance tantalum hmoov yog npaj los ntawm sodium thermal txo ntawm potassium fluorotantalate; Kev kub siab tantalum hmoov ntawm purity thiab hmoov lub cev muaj zog yuav tsum muaj siab, xws li C, O thiab particle loj tswj, yuav tsum tau melted rau hauv ib lub ingot nrog ib tug electron beam, thiab ces rov ua rau hauv tantalum hmoov los ntawm hydrogenation tawg.

Tam sim no capacitor tantalum hmoov yog txav mus rau cov kev taw qhia ntawm lub peev xwm tshwj xeeb, siab purity, txawv teb chaws tantalum hmoov muaj peev xwm tau mus txog 40, 000 ~ 50, 000 microfarads - volts / gram; 70, 000 microfarads - volts / grams ntawm tantalum hmoov tau pib sim, ib tus neeg tsim khoom tau sim ua 100, 000 microfarads - volts / grams ntawm kev taw qhia ntawm kev sib ntaus.

Ntxiv nrog rau tantalum hmoov, tantalum ntawv tseem siv rau cov ntawv ci capacitors, tantalum hlau yog siv los ua capacitor anode lead. 2000 tantalum capacitor txhua xyoo tso zis mus txog 25 billion, txhua xyoo xav tau tantalum hmoov 800 tons, tantalum hlau ze li ntawm 150 tons. Tantalum capacitors vim nws qhov kub ntau ntawm -55 ~ 125 degree capacitance kom ruaj khov, thiab rau cov ceramic capacitor tsis zoo. Nws muaj kev ntseeg siab ua ke nrog compactness, high efficiency thiab ntev txee lub sij hawm thiab lwm yam ntxwv ntawm tantalum capacitors nyob rau hauv computers, kev sib txuas lus systems, aircraft, missiles, ships thiab riam phom systems nrog lub instrumentation thiab tswj systems nyob rau hauv daim ntawv thov ntawm lub sij hawm ntev, tantalum muaj. ua daim ntawv thov tseem ceeb tshaj plaws.
