Izichasi zefilimu ezibhityileyo: izixhasi zefilimu yekhabhoni, izichasi zefilimu zekhabhoni zokwenziwa, izixhasi zefilim zetsimbi, izixhasi zefilimu ye-oxide yesinyithi, ...Funda ngokugqithisileyo -
I-Varactor diode
I-varactor diode yi-diode ekhethekileyo eyenzelwe ngokukodwa ngokomgaqo wokuba i-junction capacitance ye "PN junction" ngaphakathi kwe-diode eqhelekileyo inokutshintsha ngokutshintsha kwe-voltage esetyenzisiweyo.I-varactor diode isetyenziswa ikakhulu kwimodyuli ye-high-frequency modulatio...Funda ngokugqithisileyo -
Inductor
I-Inductor isetyenziswa ngokuqhelekileyo kwisekethe "L" kunye nenombolo, njenge: L6 ithetha inombolo ye-inductance 6. Ii-coil inductive zenziwe ngokujija iingcingo ezifakwe kwi-insulated malunga nenani elithile lokujika kwi-skeleton e-insulated.I-DC inokudlula kwikhoyili, ukuxhathisa kwe-DC kukuchasana kwe-th ...Funda ngokugqithisileyo -
I-Capacitor
1. I-capacitor imelwe ngokubanzi ngokuthi "C" kunye namanani kwisekethe (afana ne-C13 ithetha i-capacitor enombolo 13).I-capacitor yenziwe ngeefilimu ezimbini zetsimbi ezisondeleyo komnye nomnye, zihlulwe yinto ekhuselayo phakathi.Iimpawu ze-capacitor yile ...Funda ngokugqithisileyo -
Izakhono zokusebenza zovavanyo lwe-PCB ephaphazelayo
Eli nqaku liza kwabelana ngobuchule obufana nokulungelelaniswa, ukulungisa, kunye novavanyo lwebhodi yokulwa kwimisebenzi yovavanyo olubhabhayo lwereferensi kuphela.1. I-Counterpoint Into yokuqala yokuthetha ngayo kukukhethwa kwee-counterpoints.Ngokuqhelekileyo, imingxuma emibini kuphela ye-diagonal kufuneka ithathwe njengee-counterpoints.?)
