Muukadaulo wamagetsi, ma frequency ndi lingaliro wamba.
Ma frequency amagetsi amatanthawuza kusinthasintha kwa nthawi ndi nthawi mu voteji ndi panopa mu alternating current, ndiko kuti, mayendedwe ndi kukula kwa kusintha kwamakono pafupipafupi.
Mtengo wotsutsa awotsutsazitha kusiyanasiyana pama frequency osiyanasiyana, omwe makamaka amakhudza kuyankha pafupipafupi kwa chipangizo chotsutsa. Nthawi zambiri, zida zodzitchinjiriza nthawi zambiri zimawonetsa kukana kosasunthika pamlingo wocheperako, koma momwe ma frequency akuchulukira, zotsatira zina zingayambitse kusintha kwa mtengo wokana. Zotsatirazi ndi zina zomwe zingayambitse kudalira pafupipafupi:
Khungu Zotsatira:Pamaulendo apamwamba, zamakono zimakonda kuyenda pamwamba pa kondakitala osati kudutsa gawo lonse la kondakitala. Izi zimatchedwa Schottky effect, zomwe zimapangitsa kuti mtengo wokana uwonjezeke ndikuwonjezeka pafupipafupi.
Zapafupi:The mutual inductance effect ndi chodabwitsa chomwe chimachitika pakati pa ma conductor oyandikana pama frequency apamwamba. Izi zingayambitse kusintha kwa mtengo wotsutsa pafupi ndi kondakitala, makamaka m'mabwalo apamwamba a AC.
Capacitive Effect:Pamaulendo apamwamba, mphamvu ya capacitive ya zida zotsutsa imatha kukhala yofunika kwambiri, zomwe zimapangitsa kuti pakhale kusiyana pakati pamagetsi ndi magetsi. Izi zitha kupangitsa kuti mtengo wokana uwonetsere zovuta za impedance pama frequency apamwamba.
Kutayika kwa Dielectric:Ngati chipangizo chotsutsa chili ndi zida za dielectric, zinthuzi zimatha kutayika pama frequency apamwamba, zomwe zimapangitsa kusintha kwa zinthu zotsutsana.
M'mabwalo amagetsi anthawi zonse, kudalira pafupipafupi kwa kukana kumangoganiziridwa pamabwalo amtundu wa radio frequency (RF) kapena kugwiritsa ntchito pafupipafupi kwambiri. Pazinthu zambiri zotsika pafupipafupi komanso za DC, kuchuluka kwa kukana nthawi zambiri kumakhala kosavomerezeka. M'mabwalo othamanga kwambiri, mainjiniya opanga amatha kusankha zida zopangidwa mwapadera kuti zikwaniritse zofunikira zodalira pafupipafupi.

LitiresistorsAmagwiritsidwa ntchito mu ma frequency a frequency radio frequency (RF) kapena ma frequency apamwamba kwambiri, kuti apewe kutengera ma frequency pa kukana, zotsutsa zopanda inductive nthawi zambiri zimasankhidwa.
Ceramica Resistors
Thick Film Resistors
ZENITHSUN imapanga zopinga zakuda zamakanema ndi ma ceramic composite resistors, onse omwe ali a non-inductive resistors. Zachidziwikire, zotchingira mabala a waya zithanso kupangidwa kukhala mitundu yotsika ya inductance, koma osagwiritsa ntchito ma inductive ndi otsika poyerekeza ndi ma resistors amtundu wakuda ndi ma ceramic composite resistors. Chosankha chabwino kwambiri ndi ceramic kompositiresistors, omwe amatengera mapangidwe osagwiritsa ntchito inductive komanso ali ndi mphamvu zotsutsana ndi pulse.
