Chodetsa capacitors - momwe angachitire?

Chaka chilichonse zambiri pa misika ya zoweta capacitors angapezeke osati Russia, komanso kunja. Ndipo ambiri amavutika kwambiri mu chinawathandiza kumvetsa n'chakuti zolemba za. Kodi kuzilingalira izo? Ndithudi, ngati kulakwa, ndi chipangizo Simungalandire.

Kuyamba, tiona kuti kulemba capacitors anapanga motere:

1. Yoyezedwa mphamvu kuti akhoza kugwiritsa ntchito yosiyanasiyana chizindikiro ongokhala manambala a (zambiri atatu kapena anayi), ndiponso makalata, kumene kalata limasonyeza mfundo decimal, ndi kalembedwe (uF, NF, PF).
2. The kupatuka chovomerezeka kwa mphamvu mwadzina (ntchito ndi imatengedwa osowa, malingana ndi maonekedwe komanso chipangizo kopita).
3. Chovomerezeka oveteredwa voteji (mwinamwake ilo likutchedwa chovomerezeka opaleshoni voteji) - ndi chizindikiro n'kofunika, makamaka pamene ntchito m'madera mkulu-voteji).

Kulemba wa capacitors ceramic pa mphamvu adachivotera

Ceramic kapena okhazikika capacitors ali m'gulu la anthu otchuka. Childs, capacitance lakuti angapezeke pa thupi lopanda chinthu yeniyeni.

1. Funsani wa capacitors manambala atatu, woyamba awiri zimasonyeza kumene mantissa ndi mmene yamasika phindu mu m'munsi 10 kulandira chipembedzo mu picofarads, i.e. limasonyeza chiwerengero cha ziro kwa capacitor mu pikafararadah. Mwachitsanzo: 472 ungatanthauze 4700 PF (m'malo 472 PF).

2. chodetsa capacitors manambala anayi - dongosolo ofanana m'mbuyomo, koma mu nkhani iyi woyamba manambala atatu amasonyeza mantissa, ndipo lomaliza ndi mtengo wa m'munsi 10 kulandira phindu nkhope mu picofarads. Mwachitsanzo: 2344 = 234 * 10 ² PF = 23400 PF = 23,4 NF;

3. obwerawa olemba kapena chodetsa ndi manambala ndi makalata. M'kalata choncho limasonyeza kuti katunduyo (uF, NF, PF), komanso mfundo decimal ndi zithunzi - mtengo wa capacitance ntchito. Mwachitsanzo: 28P = 28 PF 3n3 = 3.3 NF. Pali nthawi zina pamene mfundo decimal amaimira kalata R.

M'pamene chizindikiro chovomerezeka opaleshoni voteji kawirikawiri amagwiritsidwa ntchito zamagetsi msonkhano, zopangidwa ndi manja ake. Ndiyo kukonza a nyali fulorosenti sadzakhala popanda kusankha kwa voteji yabwino capacitors analephera. Zikatero, chizindikiro ichi adzasonyezedwa pambuyo kuchimwa ndi mphamvu mwadzina.

Awa ndi magawo zofunika ntchito pamene chodetsa ikuchitika capacitors. Afunika adziwe posankha chipangizo yoyenera. Olemba a capacitors kunja ndi kusiyana kwawo, koma mu mzere ndi wathu m'nkhaniyi.

Bwino anasankha capacitor kudzakuthandizani polenga zipangizo zanu, komanso amathandiza kukonza amene alipo. Chinthu chachikulu kukumbukira kuti mankhwala khalidwe kungakhale kokha kwa opanga kuti akhala kufunika kumsika magetsi. Ndipo kwa mtundu uwu wa mankhwala khalidwe - kuposa chilichonse. Ndipotu, chifukwa wonongeka wa capacitor mwina kuswa zodula chigawo zida kapena chipangizo. Komanso, iwo akhoza zimadalira chitetezo chanu.
