1) Substrate:

Lub nti resistor puag cov ntaub ntawv yog muab los ntawm 96% al2O3 ceramics.Ntxiv rau qhov zoo hluav taws xob rwb thaiv tsev, lub substrate yuav tsum muaj thermal conductivity zoo heev ntawm qhov kub thiab txias.Lub cev muaj zog muaj cov yam ntxwv xws li mechanical zog.Tsis tas li ntawd, lub substrate yuav tsum tau tiaj tus thiab raug cim.Siab tiv thaiv tus qauv ntawm kev tiv thaiv.Cov electrode muab tshuaj txhuam yog luam tawm nyob rau hauv qhov chaw.

2) Resistive zaj duab xis:
Ib tug resistor muab tshuaj txhuam nrog ib tug tej yam resistivity yog luam tawm nyob rau hauv ceramic substrate, thiab ces sintered.Ruthenium dioxide yog siv ib leeg rau cov tshuaj tiv thaiv.

3) Kho zaj duab xis:
Yuav kom tswj tau lub cev resistor, nws yog ib qho tseem ceeb uas yuav tsum tau npog lub resistor zaj duab xis nrog ib tug txij nkawm zaj duab xis.Ntawm ib sab, nws plays lub luag haujlwm ntawm kev kho tshuab.Ntawm qhov tod tes, lub cev resistor yog nominally insulated los tiv thaiv tus resistor los ntawm kev sib cuag nrog cov conductors nyob ib sab thiab ua rau tsis ua hauj lwm.Nws tseem tuaj yeem tiv thaiv cov electrode los ntawm corroded los ntawm electro-transfer kua thaum lub sij hawm electro-transfer txheej txheem, uas ua rau ib tug txo nyob rau hauv lub kuj muaj nuj nqi.Cov yeeb yaj kiab tu yog cov iav uas tsis tshua muaj melting iav, uas yog luam tawm thiab sintered.Chip resistor tuam txhab
4) electrode:
Yuav kom ntseeg tau qhov zoo solderability thiab robustness ntawm lub resistor, peb-txheej electrode qauv siv ib leeg: ​​Internal.sab hauv.Sab nraud electrode.Internal electrode yog lub internal electrode txuas nrog lub cev resistor.Cov ntaub ntawv electrode yuav tsum raug xaiv.Cov zaj duab xis kuj muaj kev sib cuag tsis tshua muaj zog, muaj zog sib raug zoo nrog cov ceramic substrate, zoo tshuaj tiv thaiv, thiab yooj yim electroplating lag luam.Qee qhov yog luam tawm thiab sintered nrog nyiaj-palladium alloy.Sab electrode yog nickel-plated txheej, tseem hu ua yoj barrier txheej.Nws txoj haujlwm yog los txhim kho cov cua sov ua haujlwm ntawm vuam thiab tsis cuam tshuam cov thermal shock ntawm vuam.Nws tseem tuaj yeem zam qhov kev tsiv teb tsaws ntawm cov nyiaj ions mus rau cov txheej txheem zaj duab xis, thiab tiv thaiv cov txheej txheem sab nraud ntawm electrode tin-lead (tseem hu ua txheej txheej solderable) los ntawm corroding cov electrode sab hauv.Nws txoj haujlwm yog ua kom cov electrode muaj qhov zoo solderability thiab txuas ntxiv lub sijhawm cia ntawm electrode.Qee qhov yog electroplated nrog tin-lead alloy.

Rectangular nti resistors muab faib ua nyias zaj duab xis resistors thiab tuab zaj duab xis resistors raws li cov ntaub ntawv tsis kam.Chip inductors Hom nti inductors tseem hu ua lub zog inductors thiab siab tam sim no inductors.Chip inductance yog tus yam ntxwv ntawm lub voj kaw.Cov zaj duab xis resistor muaj siab precision thiab tsis tshua muaj kub coefficient.Lub firmness yog qhov zoo, tab sis qhov kev tiv thaiv ntau yog nqaim, haum rau cov khoom lag luam me me.Thick film resistors feem ntau yog siv hauv circuits.
