Inductance kam rau ua

Qhov sib txawv ntawm qhov tso cai yog qhov yuam kev ntawm qhov nominal inductance thiab qhov tseeb inductance ntawm tus inductor.

Feem ntau, inductors siv nyob rau hauv circuits xws li oscillation los yog filtering yuav tsum tau high precision, thiab qhov tso cai sib txawv yog ±{{0}}.2% 0.5%. Qhov tseeb ntawm coils rau coupling thiab high-frequency choke tsis siab; Qhov sib txawv ntawm qhov tso cai yog ± 10. % ~ 15%.

Qhov zoo tshaj plaws, tseem hu ua Q tus nqi lossis daim duab ntawm qhov tsim nyog, yog qhov tseem ceeb rau kev ntsuas qhov zoo ntawm inductor.

Nws yog hais txog qhov sib piv ntawm inductive reactance nthuav tawm los ntawm inductor rau nws qhov sib npaug poob tsis kam thaum ua haujlwm ntawm AC voltage ntawm qee zaus. Qhov siab dua Q tus nqi ntawm inductor, qhov tsawg dua qhov poob thiab qhov ua tau zoo dua.

Qhov zoo tshaj plaws ntawm cov inductor muaj feem xyuam rau DC tsis kam ntawm cov coil hlau, qhov dielectric poob ntawm lub kauj bobbin, thiab poob los ntawm cov tub ntxhais thiab cov ntaub thaiv npog.

Lub capacitance faib yog hais txog lub capacitance ntawm lub lem thiab tig ntawm lub kauj, nruab nrab ntawm lub kauj thiab lub hauv paus, nruab nrab ntawm lub kauj thiab hauv av, thiab nruab nrab ntawm lub kauj thiab hlau. Qhov me dua qhov faib capacitance ntawm inductor, qhov zoo dua nws cov stability. Qhov kev faib tawm tuaj yeem ua rau qhov sib npaug ntawm lub zog dissipation kuj loj dua thiab qhov zoo tshaj plaws yuav loj dua. Txo cov kev faib tawm uas feem ntau siv cov xaim qhwv cov hlau los yog cov hlua khi hlua khi, qee zaum kuj siv cov xov tooj ntawm tes winding.

Rated tam sim no

Qhov ntsuas tam sim no yog qhov siab tshaj plaws tam sim no uas lub inductor tuaj yeem tiv taus nyob rau hauv qhov chaw ua haujlwm tso cai. Yog hais tias qhov kev khiav hauj lwm tam sim no tshaj qhov ntsuas tam sim no, tus inductor yuav hloov nws qhov kev ua haujlwm tsis zoo vim yog lub zog hluav taws xob, thiab txawm tias hlawv tawm vim overcurrent.
