Mune engineering yemagetsi, frequency ipfungwa yakajairika.
Mafambisirwo emagetsi zvinoreva kuwanda kwekuchinja kweperiodic muvoltiji uye ikozvino mukuchinjana ikozvino, ndiko kuti, kutungamira uye ukuru hwekuchinja kwazvino pane imwe frequency.
Kupokana ukoshi aresistorinogona kusiyanisa pama frequency akasiyana, ayo anonyanya kusanganisira frequency mhinduro maitiro eiyo resistor mudziyo.Kazhinji kutaura, zvigadziriso zvinodzivirira zvinowanzo ratidza kukosha kwekupokana mune yakaderera frequency renji, asi sezvo frequency inowedzera, mamwe mhedzisiro inogona kukonzera shanduko mukukosha kwekupokana.Izvi zvinotevera zvimwe zvinhu zvinogona kukonzera kuramba frequency kutsamira:
Skin Effect:Pamafambiro akakwirira, ikozvino inowanzoyerera nepamusoro pemuitisi kwete kuburikidza nepakati pese-chikamu chemuitisi.Izvi zvinodaidzwa kuti Schottky athari, izvo zvinoita kuti kukosha kwekupikisa kuwedzere nekuwedzera frequency.
Proximity Effect:The mutual inductance effect chiitiko chinoitika pakati pemaconductors ari padhuze pakakwirira.Izvi zvinogona kukonzera shanduko mukupokana ukoshi padhuze nekondukita, kunyanya mune yakakwira-frequency AC maseketi.
Capacitive Effect:Pamafafitera epamusoro, iyo capacitive mhedzisiro yezvidziviriro zvinodzivirira inogona kuve yakakosha, zvichikonzera musiyano wechikamu pakati pezvino uye voltage.Izvi zvinogona kukonzera kukosha kwekupokana kuratidza kwakaoma impedance pane yakakwirira frequency.
Dielectric Kurasikirwa:Kana chigadziro chinopikisa chiine dielectric zvinhu, zvinhu izvi zvinogona kukonzera kurasikirwa pamafafitera akakwirira, zvichiita kuti kuchinja kwemaitiro ekupikisa.
Mumaseketi ese emagetsi, kutsamira kwefrequency yekupokana kunowanzo kutariswa mune yakakwira-frequency radio frequency (RF) maseketi kana chaiwo epamusoro-frequency application.Kune yakawanda yakaderera-frequency uye DC zvikumbiro, iyo frequency mhedzisiro yekupokana kazhinji haina basa.Mumaseketi akakwira-frequency, mainjiniya edhizaini anogona kusarudza akagadzirirwa zvakanyanya-frequency resistor zvishandiso kuti asangane nefrequency dependence zvinodiwa.
Frequency-dhiyagiramu-ye-resistance-coefficient
Riniresistorsanoiswa mu-high-frequency radio frequency (RF) maseketi kana chaiwo high-frequency application, kudzivirira pesvedzero yefrequency pakupokana, zvisiri-inductive resistors zvinowanzosarudzwa.
Ceramica Resistors
Makobvu Film Resistors
ZENITHSUN inogadzira gobvu remafirimu resistors uye ceramic composite resistors, ese ari easina-inductive resistors.Ehe, waya maronda ekudzivirira anogona zvakare kuitwa akaderera inductance mhando, asi iyo isiri-inductive mhedzisiro yakaderera kune gobvu firimu resistors uye ceramic composite resistors.Sarudzo yakanakisa ndeye ceramic compositeresistors, iyo inotora isiri-inductive dhizaini uye ine yakasimba anti pulse kugona.
