Mune chip common mode inductor , zvigadzirwa zvakasiyana zvinogona kusarudzwa zvinoenderana nehunhu uye saizi zvinodiwa. Gv Electronics, fekitori ye chip inductor , inogoverana newe masarudzire akakodzera COMMon-mode choke coil kubva pachimiro chemaonero.
Unogona Kuda Izvi Usati Warodha
1. Mashandisiro ekusiyanisa kutapurirana uye zvakajairika maitiro anodzipa makoiri
Tisati tatsanangura hunhu hweakajairwa modhi inodzipa coils, ngatitangei tasuma iyo pfungwa yeyakajairika modhi chiratidzo uye yekusiyanisa modhi chiratidzo.
Differential kutapurirana inzira inoshandiswa kune yakakwirira-kumhanya kufambisa data. Somuenzaniso, MIPI? inoshandiswa mukamera uye chidzitiro chemafoni emafoni, HDMI?, DisplayPort, uye USB yemakomputa ese inzira dzekutapurirana dzakasiyana.
Mumitsara miviri yekutapurirana kwakasiyana, chikamu chemumwe nemumwe (ichiratidza kutsauka kweiyo voltage waveform uye yazvino waveform) inodzoserwa chiratidzo chekufambisa.
Ichi chiratidzo chinodaidzwa kuti mutsauko modhi chiratidzo, uye kuendesa data kunoitwa kuburikidza nekusiyanisa modhi chiratidzo. (Differential mode dzimwe nguva inonzi seyakajairika mode). Kuenzaniswa neakasiyana masaini masaini, kune zvakare chiratidzo chinonzi common mode chiratidzo, icho chinopfuudzwa muchikamu chimwe chete mumitsetse miviri.
Kune chip common mode inductors yemitsara yemasaini, iyo yakajairika modhi chiratidzo chiratidzo chisingadiwe, ndiko kuti, ruzha, rwunodaidzwa kuti common mode ruzha.
Differential modhi masiginecha anosanganiswa neyakajairika modhi ruzha. Kana chiratidzo chekusiyanisa chagamuchirwa, masaini emhando yekusiyanisa anosimbisa mumwe nemumwe, uye iyo yakajairika modhi ruzha runodzima mumwe nemumwe kunze. Nzira dzakasiyana dzekutumira dzakadai hadzina kubatwa neruzha rwakajairika.
Iwo akasiyana-siyana anopfuudzwa masaini emwaranzi anocherechedzwa ari kure, uye masaini anoiswa pamusoro peumwe neumwe. Panguva ino, iyo yekusiyanisa modhi masaini anodzima mumwe nemumwe kunze, uye yakajairika modhi ruzha runosimbisa mumwe nemumwe. Kureva kuti, inotapukirwa neruzha rwemodhi iri kure.
Kana matambudziko eruzha akafanana aitika, iyo yakajairika modhi inodzipa coil inobatanidzwa munhevedzano kune yekusiyanisa yekufambisa mutsara kuti ibvise zvinobudirira iyo yakajairika modhi ruzha.
2. Maonero ehunhu hweakajairwa modhi anodzipa makoiri
Muchokwadi, iyo yekusiyanisa modhi ruzha rwakaderedzwa nekuda kweiyo yakajairika mode inodzipa coil. Uye zvakare, kusiyanisa-modhi uye yakajairika-modhi masiginecha anowana kuderedzwa kwakasiyana nekuda kwema frequency akasiyana. Hunhu hweiyo yakajairwa modhi yekudzipa coil inomiririrwa neiyo frequency maitiro eiyo yekusiyanisa modhi yekuisa kurasikirwa Sdd21 uye yakajairika modhi yekuisa chiratidzo Scc21. (Sdd21 uye Scc21 chikamu cheiyo yakasanganiswa-modhi 4-chiteshi S-paramita)
Frequency maitiro eyakajairwa nzira yekuisa kurasikirwa Scc21. Iyo yakadzika kurasikirwa kwekuisa, iyo yakakura kurasikirwa. Iyo yakakwirira kuwanda kweiyo differential mode chiratidzo, iyo yakakura kurasikirwa. Iyo yakajairika nzira yekuisa kurasikirwa Scc21 icurve ine peak, uye mhedzisiro yekubvisa yakajairika modhi ruzha inosiyana zvichienderana nekuwanda.
Iyo yechiratidzo frequency ye chip common mode inductor yechiratidzo mutsara inosiyana zvichienderana neiyo interface nzira, uye yakajairika mode inodzipa coil inochinjawo saizvozvo.
Kunyangwe iyo yakajairwa modhi yekudzipa coil yakakodzera inogona kutongwa zvinoenderana neyekutapurirana chiratidzo waveform. Kazhinji, iyo yekucheka-kubvisa frequency yeiyo yakajairwa modhi inodzipa coil inopeta katatu iyo frequency yechiratidzo cheiyo mutsauko wekutapurirana yakatarwa. Iyo inodaidzwa kuti cutoff frequency ndiyo frequency apo iyo yekusiyanisa modhi yekuisa kurasikirwa inova 3 dB.
Nekudaro, kunyangwe iri isingasviki ka3, kune akawanda matambudziko muchiratidzo waveform, uye iyi ireferensi zvakanyanya. (Nekuti chiyero chemhando yechiratidzo senge mepu yeperforation inotarwa pane yega yega interface, inozotongwa kuti yakakodzera here kana kuti kwete zvinoenderana nechiyero ichi)
Kune rimwe divi, ruzha rwedambudziko uye kuwanda kwaro kunosiyana kubva kune terminal kuenda kune terminal, uye zvinoenderana neiyo frequency maitiro eakakodzera akajairika-modhi yekuisa kurasikirwa anochinja zvinoenderana.
Semuyenzaniso, kana ruzha rukaitika runodarika kukosha kwemuganho wakataurwa nechiyero chemutemo wekuburitsa, zvinonyanya kushanda kusarudza iyo ine hombe yakajairwa yekuisa kurasikirwa mubhendi reruzha irworwo.
Uye zvakare, yakajairika modhi ruzha runoratidzwa nekusiyanisa kutapurirana inogona kukanganisa iyo yayo isina waya yekutaurirana mabasa akadai seLTE neWi-Fi. Zvinogona kutariswa kuti yakajairika modhi ruzha rweiyo yakafanana frequency yekutaurirana isina waya inoitika, uye antenna inogamuchira iyi ruzha. Izvi zvinodaidzwa kunzi suppressed reception sensitivity. Panguva ino, nekuisa yakajairika modhi yakachinga coil, kuburitsa kweyakajairika modhi ruzha kunogona kudzvinyirirwa uye yekugamuchira senitivity inogona kuvandudzwa.
Izvo zviri pamusoro ndeye sumo kune hunhu hweSMD common mode inductors. Kana iwe uchida kuziva zvakawanda nezve SMD inductors, ndapota taura nesu.
hunyanzvi mukugadzirwa kwemhando dzakasiyana-siyana dzemavara ring inductors, beaded inductors, vertical inductors, tripod inductors, chigamba inductors, bar inductors, common mode coils, high-frequency transformers uye mamwe magineti zvikamu.
