Kubunjineli bombane, i-frequency yingcamango eqhelekileyo.
Ukuphindaphindwa kombane kubhekisa kumaxesha ngamaxesha otshintsho kumbane kunye nangoku kumbane otshintshayo, oko kukuthi, isalathiso kunye nobukhulu botshintsho lwangoku kwifrikhwensi ethile.
Ixabiso lokuchasa aisixhasizinokwahluka kwiifrikhwensi ezahlukeneyo, ezibandakanya ikakhulu iimpawu zokuphendula rhoqo kwisixhobo esichasayo.Ngokuqhelekileyo, izixhobo ezixhathisayo zibonisa ixabiso elizinzileyo lokumelana noluhlu oluphantsi lwamaza, kodwa njengoko ukuphindaphinda kunyuka, ezinye iziphumo zinokubangela utshintsho kwixabiso lokumelana.Oku kulandelayo yeminye imiba enokubangela uxhathiso ngamaxesha amaninzi:
Impembelelo yolusu:Kwii-frequencies eziphezulu, i-current ivame ukuhamba ebusweni bomqhubi kunokuba ijikeleze yonke i-cross-section ye-conductor.Oku kubizwa ngokuba yi-Schottky effect, ebangela ukuba ixabiso lokuchasa linyuke ngokunyuka rhoqo.
Impembelelo yokusondela:Umphumo we-mutual inductance yinto eyenzekayo phakathi kwabaqhubi abasondeleyo kwiifrikhwensi eziphezulu.Oku kunokubangela utshintsho kwixabiso lokumelana kufuphi ne-conductor, ngakumbi kwiisekethe ze-AC ze-high-frequency.
I-Capacitive Effect:Kwii-frequencies eziphezulu, i-capacitive effect ye-resistive effect ingaba yinto ebalulekileyo, ekhokelela kumahluko wesigaba phakathi kwangoku kunye nombane.Oku kunokubangela ukuba ixabiso lokuchasana libonise i-impedance enzima kumaza aphezulu.
Ilahleko yeDielectric:Ukuba isixhobo esichasayo siqulethe izinto ze-dielectric, ezi zixhobo zingabangela ilahleko kwii-frequencies eziphezulu, ezikhokelela ekutshintsheni kumaxabiso okumelana.
Kwiisekethe ze-elektroniki ngokubanzi, ukuxhomekeka rhoqo koxhathiso kudla ngokuqwalaselwa kuphela kwiisekethe zerediyo zerediyo eziphakamileyo (RF) okanye usetyenziso oluthile lwefrikhwensi ephezulu.Kwiinkqubo ezininzi eziphantsi-frequency kunye ne-DC, isiphumo sokuphindaphinda kokuchasana sihlala singahoywa.Kwiisekethe ezisebenza ngokuphindaphindiweyo, iinjineli zoyilo zinokukhetha izixhobo ezichasene nezande-frequency ezikhethekileyo ukuhlangabezana neemfuno zokuxhomekeka rhoqo.

Niniresistorszisetyenziswa kwiisekethe zerediyo ze-high-frequency radio frequency (RF) okanye kwi-high-frequency applications ethile, ukunqanda impembelelo ye-frequency on the resistance, i-non-inductive resistors idla ngokukhethwa.
I-Ceramica Resistors
IiResistors zefilimu ezishinyeneyo
I-ZENITHSUN ivelisa izichasi zefilimu ezishinyeneyo kunye nezichasi ze-ceramic ezihlanganisiweyo, zombini ezizezezichasi ezingezizo.Ewe kunjalo, izichasi zenxeba zocingo zisenokwenziwa zibe ziindidi ze-inductance ezisezantsi, kodwa isiphumo esingeyo-inductive singaphantsi kwi-resistors yefilimu eshinyeneyo kunye ne-ceramic composite resistors.Olona khetho lungcono luyi-ceramic compositeresistors, eyamkela uyilo olungeyo-i-inductive kwaye inamandla okumelana ne-pulse.
