Kodi SMD inductor imagwira ntchito yanji mu nyali zopulumutsa mphamvu za LED?

Popeza ma chip inductors amatha kukulitsa moyo wautumiki wazinthu zambiri zamagetsi ogula, kupititsa patsogolo mtundu wazinthu, kusakhala bwino, ndi magwiridwe antchito, agwiritsidwa ntchito ndi opanga ambiri.

Osagwiritsidwa ntchito pazida zamagetsi zokha, komanso zida zomvera, zida zama terminal, zida zam'nyumba ndi zinthu zina zamagetsi ndi zamagetsi, kuti maginito amagetsi asasokonezedwe, komanso nthawi yomweyo, samasokoneza ma sign kapena ma radiation yamagetsi. zotulutsidwa ndi zida zina zozungulira. .

Nyali zopulumutsa mphamvu zimagwiritsidwa ntchito kwambiri pamoyo wathu; ndipo nyali zopulumutsa mphamvu za LED zimapangidwa makamaka ndi ma semiconductor kuwala-emitting diode; iwo ndi mtundu wa kuwala komwe kumadya mphamvu zochepa ndipo kumakhala ndi moyo wautali wautumiki.

Dera lamkati la nyali yopulumutsa mphamvu ya LED ndi bolodi lamagetsi, makamaka kuphatikiza ma electrolytic capacitors, resistors, inductors, ceramic capacitors, ndi zina zambiri, zomwe ochepa ndi chip power inductors, ndipo gawo lake ndilofunika kwambiri.

makamaka kutsekereza AC ndi DC, ndikuletsa ma frequency apamwamba komanso otsika pafupipafupi (sefa). Zachidziwikire, dera lamagetsi limatchinga AC ndi DC. Zitha kuwoneka kuti kukana kwa ma chip power inductors ku DC kuli pafupifupi ziro.

Pansi pa zomwe zikuchitika kuti dera limalola kudutsa, chip inductance imalepheretsa kupita kwa AC point, imateteza bolodi kuti isawonongeke, ndikuwonjezera kwambiri moyo wautumiki wa LED.
