Ndikukhulupirira kuti anthu ambiri amasokonezeka poyerekezera ndiotetezedwainductorndi osatetezedwainductor. Malinga ndi kusiyana kwa maginito shielding performance, pali mayina awiri osiyana otetezedwainductorndi osatetezedwainductor. Zotetezedwainductorzikuphatikizapo chipinductorndi mawonekedweinductor, ndi momwemonso kwa osatetezedwainductor.

Ndiye timachita bwanji zone zotetezedwainductorndiosatetezedwainductor? Kodi pali kusiyana kotani pakati pawo? Mkonzi wa Xinchenyang Electronics afotokoza kuchokera kuzinthu zitatu zotsatirazi.

1. Kusiyanitsa pakati pa otetezedwainductorndi osatetezedwainductorm'mawonekedwe

Chotchinga chotchinga chili ndi mawonekedwe otchingira maginito kunja, chifukwa chake mapindidwe a koyilo ayenera kukhala osatetezedwa.inductorkuchokera kumawonekedwe, ndipo kupindika kwa koyilo sikungawonekere kuchokera ku mawonekedwe a chotchinga chotchinga.

Koma pali chinthu chimodzi chokha chodziwikiratu: koyilo yosawonekayo sikuti ndi chotchinga chotchinga, koma itha kukhalanso chowongolera chopangidwa ndi I chokhala ndi manja osinthasintha.

Chachiwiri, mawonekedwe a maginito ozungulira amasiyanitsa otetezedwainductorndi osatetezedwainductor

III. 1. Maginito ozungulira maginito a inductor otetezedwa ndi njira yotsekedwa ya maginito: mawonekedwe otsekedwa a maginito ozungulira amapangidwa ndi maginito a maginito omwe ali ndi maginito ochepa kwambiri, zomwe zikutanthauza kuti maginito a maginito ndi toroidal core, yomwe ndi yotsekedwa maginito. kapangidwe.

4. Maginito ozungulira maginito a osatetezedwainductorndi mawonekedwe otseguka a maginito: popeza mawonekedwe a maginito ozungulira akuwonekera, amakhala ndi mpweya woonekera kwambiri, ndipo kulepheretsa kwake kumakhala kwakukulu, zomwe zikutanthauza kuti maginito apakati ndi U-woboola kapena EE.

Zisanu, zitatu, kusiyanitsa zotetezedwainductorndi osatetezedwainductorpakuchita bwino

6. Chifukwa cha mitundu yosiyanasiyana ya maginito yotchinga ya ma inductors otetezedwa ndi ma inductors osatetezedwa, pansi pa zofanana.inductorndi ntchito zamakono, voliyumu ya inductors otetezedwa ndi yaikulu kuposa ya inductors osatetezedwa.

7. The inductor wosatetezedwa ali ndi makhalidwe a high saturation maginito mlingo, kakang'ono ndi impedance otsika. Imayang'ana kwambiri ma inductors a plug-in, gawo la chip inductors GCD mndandanda (omwe posachedwa asinthidwa ndi ma inductors otetezedwa), ndi ma inductors a ndodo.

8. 3. Inductor yotetezera ili ndi makhalidwe amphamvu kwambiri, kukana kutsika komanso zamakono zamakono. Amagwiritsidwa ntchito kwambiri m'mabwalo omwe ali ndi zofunikira kwambiri za EMC, zomwe zimaphatikizapo kutumiza ma siginecha, kuwerengera mwanzeru, ndi zina zambiri, monga mafoni am'manja, makompyuta, zomvera zapamwamba ndi zina zotero.
