Q: Ceramic capacitors inokanganisa nekukwegura zviitiko
Ceramic capacitors inobatwa nekuchembera zviitiko zvine chekuita nekuchinja kweiyo dielectric crystal chimiro, iyo inozviratidza sekuchinja kwecapacitance uye dissipation chinhu mushure mekutanga kupfurwa kweiyo dielectric zvinhu.Zvinoenderana nemamodheru akatarwa, EIA Kirasi I dielectric zvinhu zvinokanganisika uye zvinozivikanwa zvakanyanya sekusina kuchembera, nepo EIA Kirasi II dielectric zvinhu zvinokanganiswa zvine mwero uye EIA Kirasi III zvinhu zvinowanzokanganiswa zvakanyanya.Iyi nzira yekuchembera inogona kugadzirwa patsva (kana mudziyo “de-aging”) nekuratidzwa kune tembiricha iri pamusoro pe dielectric's Curie tembiricha kwenguva yakareba yakakwana yekubvumira chimiro chekristaro kuti chiite zvakare;iyo yakakwirira tembiricha, ipfupi nguva inodiwa.Sezvo tembiricha yeCurie yeakawanda eceramic dielectrics yakadzikira pane iyo inosangana mumazhinji ekushongedza maitiro, zvinogoneka kuti mudziyo uchave wakura zvishoma panguva yegungano.
Uhu hunhu hwekuchembera hwechikamu hunowanzo kuratidzwa sechikamu chekuchinja kwehukwanisi pamakore gumi emaawa, zvichienderana nekugona kuyerwa pa "kupisa kwekupedzisira," nguva yekupedzisira iyo chikamu ichipisa pamusoro pekupisa kwayo kweCurie kwenguva yakakwana kuti ichinje kristaro yayo. chimiro.Mune mamwe mazwi, capacitor ine mwero wekuchembera we (-) 5%, yakayerwa pa100uF mu "oven nyowani" state, inotarisirwa kuyera ingangoita 95,90 uye 85uF mushure me1, 10 uye 100 maawa kubva muchoto. , zvichiteerana.
Zviri pachena kuti izvi zvinomutsa mubvunzo wekuti chii chinonzi capacitance yechikamu chinofanira kunge chiri, uye kana iyo mari inogara ichichinja, chikamu chichashandiswa pasherufu kunyange kana isina kushandiswa mukugadzirisa kwayo kwepakutanga.Iyo indasitiri miyero EIA-521 uye IEC-384-9 inogadzirisa nyaya iyi, ichinyanya kutaura kuti chikamu chinofanira kusvika chayo chakatarwa kushivirira kukosha kwemaawa 1000 (anenge mazuva makumi mana nemaviri) mushure mekupisa kwekupedzisira.Mucherechedzo wemakore gumi anotevera (10K uye 100K maawa) anodudzira kune zvishoma pamusoro pegore rimwe uye zvishoma anopfuura makore gumi nerimwe zvichiteerana.Kuti uwedzere kuomesa zvinhu, kuchembera kunoitika pamwero wetembiricha inotsamira;kusvika kuCurie tembiricha ye dielectric, kuwedzera kwekushisa kwemudziyo kunowanzo mhanyisa maitiro ekukwegura.
Sezvo kuchembera zviitiko zvichigona kuita kuti michina ioneke kunze kwekushivirira kwavo kwakatarwa, vagadziri vezvigadzirwa uye vaongorori vekugadzira vanofanirwa kuziva chokwadi ichi;kuyedzwa kwezvichangobva kucheneswa zvikamu zvinofanirwa kutarisira zvishoma zvakakwirira capacitance kukosha, uye dhizaini inofanirwa kunge iine muganho wakakwana kuti ugare wakajairwa kushanda kwechishandiso nekukura.Maseketi ekushandura magetsi muenzaniso wakanaka wekuti izvi zvinogona kukonzera njodzi yakakomba, sezvo ceramic capacitors kazhinji inoguma ichikanganisa zvishwe zvekudzora zvemaseketi akadaro, kungave semuripo wetiweki zvikamu kana sefirita zvinhu.Zvirongwa zvinoratidzika zvakagadzikana pasi pesimba re capacitor kuchembera panguva yegungano rinogona kunge risina kugadzikana nekufamba kwenguva, sezvo kurasikirwa kwekwanisi nekuda kwekukwegura kunokanganisa simba rekutonga loop.Chinonyanya kukosha, kana yakagadzikana capacitance kukosha nekufamba kwenguva, dzivisa kushandisa zvinooneka zera capacitor.
Zhejiang NeoDen Technology Co., LTD., yakavambwa muna 2010, isu tiri pachinzvimbo chakanaka kwete chete kukupa iwe wemhando yepamusoro pnp muchina, asiwo yakanakisa mushure mekutengesa sevhisi.Mainjiniya akadzidziswa zvakanaka anokupa chero rutsigiro rwehunyanzvi.
10 mainjiniya ane simba mushure mekutengesa sevhisi timu inogona kupindura vatengi mibvunzo uye kubvunza mukati maawa masere.
Mhinduro dzehunyanzvi dzinogona kupihwa mukati memaawa makumi maviri nemana zvese zuva rebasa uye mazororo.
