Yumbu Capacitors: description, iri

Mene ne tukwane? A amfani da haka ya kira samfurin sanya ta taro da harbe-harben, yafi lãka. Da dabara kuma unsa a yumbu abu da irin wannan tsarin, amma lãka a su da kõme ba, ko da shi ne ba a adadi kaɗan. Wadannan sun hada da yumbu capacitor da ake amfani da matsayin capacitor dielectric.

yumbu capacitors

Irin kayayyakin da aka halin high lantarki yi, kananan size da kuma low cost. Yumbu capacitors suna yadu amfani da rediyo haihuwarka. Su ne akai iya aiki da kuma trimmers.

Iri capacitors tare da m capacitance

Thermostable yumbu capacitors amfani da lantarki da kuma oscillators na high kwanciyar hankali oscillators. termokompensiruyuschie abubuwa aka yi amfani da rage yawan zafin jiki. A musamman kungiyar na ferroelectric yumbu capacitor a cikinsa amfani da dielectric ferroelectric tukwane - wani abu da sosai high dielectric akai (ga dama dubu) a cikin wani takamaiman zafin jiki fuska. Wadannan kayayyakin ne halin da high mita yumbu mafi girma iya aiki domin wannan size.

A yumbu tubular capacitor (CT-1, CT-2) - bakin ciki-walled tube, cikin matsanancin da ciki saman na wanda aka rufe da Layer na azurfa.

Capacitor yumbu Disc (CH1, KD2) da kuma Disc ferroelectric yumbu juna (KDS1, KDS2, DTP3) ne madauwari yumbu farantin zuwa farantin a cikin nau'i na bakin ciki yadudduka na azurfa.

Yumbu, roba bochenochny da matsawa rabi (KOB1, KOB2, KOB3) - yumbu Silinda na, a kan tushen da abin da aka ma amfani da lantarki.

A launi makirci da kuma muhimmancinsa

Launi daban-daban suna fentin a cikin samfurin CT CDS, CD et al., Nuna a fakaice kwanciyar hankali na capacitance da zazzabi. Blue, blue, da launin toka Paint ne amfani a idan capacitance na capacitor zuwa da zazzabi canje-canje amsa qananan hanya. Irin wannan abubuwa suna kira zafi barga. Red da kuma kore launi yana nufin cewa da yawan zafin jiki ƙaruwa Manufacturing damar za ta rage muhimmanci - shi termokompensiruyuschie capacitors. Orange nuna cewa a cikin hali na zazzabi canje-canje a cikin wani m kewayon ganga kayayyakin zai bambanta wajen karfi (duk da haka a dakin da zazzabi capacitance zauna barga).

Nau'in na yumbu trimmer capacitors

Wadannan kayayyakin an tsara su don shige (gyara) sigogi na oscillating haihuwarka, kara kira a matsayin Semi-bambance-bambancen. A takaice dai look at kowane daga cikinsu.

Yumbu trimmer capacitor (CCP) kunshi wani yumbu tushe (stator) da kuma m yumbu faifai (na'ura mai juyi). Drive a kan aksali ne a haɗe zuwa stator, kuma shi za a iya juya su tare da sukudireba. Azurfa, farantin-dimbin yawa sassa, amfani da jirgin sama na biyu aka gyara. da na'ura mai juyi ne a dielectric abu. Bayan juyawa dabam zumunta sakawa faranti, bi da bi, da kuma capacitance therebetween.

Trimmer capacitor yumbu tube (COSTA) - da sunan kansa ya ce da samfurin a cikin tambaya yana da wani nau'i na tube. A ta ciki surface ne ma mai rufi na bakin ciki azurfa gyarawa rufi - a karfe sanda tare da wani dunƙule thread. Bayan juyawa (cimma ta wajen wani sukudireba) capacitance canje-canje saboda da shigar ko fitarwa shaft na tube.

Capacitance yumbu capacitors

Ko 10-20 shekaru da suka wuce, saboda matsaloli da dangantaka da samar da aka ambata capacitors, da samfurin nasa ne da category na kananan iya aiki da na'urorin. More kwanan nan, a yumbu capacitor 1 uF kowa zai ba ni mamaki, amma a 10 uF kashi riskarsa kamar m.

Amma a yau, ci gaban fasaha a yarda wasu masana'antun to bayyana rediyo aka gyara a kan nasara na iya aiki da iyaka a wannan capacitors zuwa 100 uF, amma su sun tabbatar da wannan ba iyaka.
