Ebunjiniyela bukagesi, imvamisa ingumqondo ojwayelekile.
Imvamisa kagesi isho imvamisa yezinguquko zezikhathi ezithile ku-voltage kanye nezamanje ekushintshaneni kwamandla, okungukuthi, isiqondiso nobukhulu boshintsho lwamanje ngemvamisa ethile.
Inani lokumelana lika-aisixhasizingahluka kumafrikhwensi ahlukene, okubandakanya ikakhulukazi izici zokuphendula imvamisa yedivayisi ephikisayo. Ngokuvamile, izisetshenziswa eziphikisayo ngokuvamile zibonisa inani eliqinile lokumelana nebanga eliphansi lefrikhwensi, kodwa njengoba imvamisa inyuka, eminye imiphumela ingase ibangele izinguquko enanini lokumelana. Okulandelayo ezinye izici ezingabangela ukuncika kwemvamisa yokumelana:
Umphumela Wesikhumba:Kumafrikhwensi aphezulu, i-current ivamise ukugeleza ebusweni bomqhubi kunokuba idlule kuyo yonke ingxenye ye-cross-conductor. Lokhu kubizwa ngokuthi umphumela we-Schottky, obangela ukuthi inani lokumelana likhule ngokunyuka kwemvamisa.
I-Proximity Effect:Umthelela we-mutual inductance yinto eyenzeka phakathi kwamakhondaktha aseduze kumafrikhwensi aphezulu. Lokhu kungase kubangele izinguquko kunani lokumelana eduze ne-conductor, ikakhulukazi kumasekethe e-AC anemvamisa ephezulu.
I-Capacitive Effect:Kumafrikhwensi aphezulu, umthelela we-capacitive wamadivayisi aphikisayo ungase ubonakale, okuholela kumehluko wesigaba phakathi kwamanje kanye ne-voltage. Lokhu kungabangela inani lokumelana ukuze libonise i-impedance eyinkimbinkimbi kumafrikhwensi aphezulu.
Ukulahleka Kwe-Dielectric:Uma idivayisi ephikisayo iqukethe izinto ze-dielectric, lezi zinto zingabangela ukulahlekelwa kumafrikhwensi aphezulu, okuholela ekushintsheni kumanani okumelana.
Kumasekhethi e-elekthronikhi evamile, ukuncika kwefrikhwensi yokumelana kuvame ukucatshangelwa kuphela kumasekhethi efrikhwensi yomsakazo we-high-frequency (RF) noma izinhlelo zokusebenza ezithile zamafrikhwensi aphezulu. Ezinhlelweni eziningi ze-low-frequency kanye ne-DC, umphumela wokuvama kokumelana ngokuvamile awunaki. Kumasekhethi anemvamisa ephezulu, onjiniyela bokuklama bangakhetha amadivayisi aklanywe ngokukhethekile amelana nemvamisa ukuze ahlangabezane nezidingo zokuncika kwemvamisa.

Niniresistorsasetshenziswa kumasekhethi omsakazo we-high-frequency radio frequency (RF) noma izinhlelo zokusebenza ezithile zamafrikhwensi aphezulu, ukugwema ithonya lemvamisa ekuphikiseni, izimbangi ezingasebenzisi inductive zivame ukukhethwa.
I-Ceramica Resistors
Ama-Resistors Amafilimu Aqinile
I-ZENITHSUN ikhiqiza izinto ezimelana nefilimu eziwugqinsi kanye nezinto eziphikisayo eziyinhlanganisela ye-ceramic, zombili okungezona izinto eziphikisayo. Vele, izinqamuleli zenxeba ngocingo nazo zingenziwa zibe izinhlobo eziphansi zokugudluzwa, kodwa umphumela ongaguquki ungaphansi kokuphikiswa kwefilimu okuwugqinsi kanye nezimbangi ze-ceramic composite. Inketho engcono kakhulu yinhlanganisela ye-ceramicresistors, ezamukela idizayini engeyona inductive futhi enekhono eliqinile lokulwa nokushaya kwenhliziyo.
