Qhov ntsuas tam sim no qhia txog tus nqi tam sim no uas tsis ua rau fusing thaum siv stably. Yog tias qhov ntsuas tam sim no dhau los thaum siv, fusion yuav tshwm sim thaum tsis xav tau fusion (saib Resistor-9: Qhov Zoo Kub Kub Tus Kheej Resistor (PTC)). Xav tias oxidation, expansion thiab contraction tshwm sim los ntawm kev siv mus sij hawm ntev yuav ua rau kom tus nqi tiv thaiv, qhov kev pom zoo tam sim no rau qee cov khoom yog kwv yees li 70% ntawm cov ntsuas tam sim no. Qhov no yog hu ua steady-state derating.
Lub hauv paus ruaj khov tam sim no ntawm Circuit Court siv tuaj yeem xam los ntawm qhov ruaj khov-state derating coefficient thiab kub derating coefficient siv cov qauv hauv qab no:
Thaum lub Circuit Court ruaj khov-lub xeev tam sim no Tsawg dua lossis sib npaug rau tus nqi tam sim no × khov kho-lub xeev derating coefficient × kub derating coefficient AC waveform, thov siv tus nqi siab tshaj tam sim no raws li qhov tsis muaj zog tam sim no es tsis yog tus nqi tiag tiag ntawm qhov tam sim no waveform. Fusing tam sim no hais txog qhov tam sim no uas txiav tawm hauv Circuit Court. Yuav kom txiav tawm qhov txawv txav tam sim no hauv Circuit Court, nws yuav tsum tau teem rau ntau tshaj 2 npaug ntawm tus nqi tam sim no. Yog tias lub sijhawm fusing tsawg dua 1 thib ob, qhov sib txawv ntawm qhov sib txawv tshwm sim los ntawm ib puag ncig cuam tshuam xws li mounting pad loj thiab cov khoom siv substrate yuav me me. Txawm li cas los xij, yog tias nws ntau dua 1 thib ob, qhov cuam tshuam ib puag ncig yuav zoo heev. Yog li ntawd, nws yuav tsum tau nqa tawm ua ntej los ntawm qhov tseeb Circuit Court. paub meej.
