SMD fais fab inductor yog siv nyob rau hauv daim ntawv thov xws li lub hwj chim mov mus rau lub hwj chim converters. Lawv yog cov me me piv rau cov qauv tsim los ntawm lub qhov, nrog cov khoom siv ntau dua (cov khoom siv hauv ib cheeb tsam) thiab ntau qhov sib txuas rau ib feem. Lawv muaj tus nqi pib qis dua thiab xav tau sijhawm tsawg dua rau kev tsim khoom. Lawv kuj tso cai yooj yim dua thiab ceev automated los ua ke.
Lub "SMD" nyob rau hauv SMD fais fab inductor stands rau Surface Mount Device, qhia tias lawv yog tsim los rau saum npoo mount technology (SMT) los ua ke ntawm luam Circuit Court boards (PCBs). Qhov no tso cai rau automated thiab loj ntau lawm txheej txheem, ua rau lawv haum rau high-volume manufacturing.
SMD fais fab inductor rau cov ntawv thov xws li cov khoom siv hluav taws xob mus rau lub zog hloov hluav taws xob. Core hom muaj xws li ferrite thiab nias hlau hmoov nrog topologies xws li: tsis-shielded, shielded, nias hlau hmoov, ferrite coated, thiab wirewound nti inductors.
Qhov zoo
1. Kev tiv thaiv ntau lub ntim kom cov khoom muaj kev nyab xeeb hauv kev thauj mus los;
2. Ua tiav cov khoom lag luam, kev tsim qauv tsim muaj;
3. Shielded inductors sib sau ua ke los ntawm kev tswj hwm kev sib koom ua ke, kev ua haujlwm ruaj khov hluav taws xob;
4. Ua cov khoom tsis pub dawb, RoHS thiab REACH ua raws.
Nta
- Siab zog, siab saturation tam sim no, tsis tshua muaj impedance;
- Haum rau nto mount;
- High tshav kub kuj thiab zoo heev solderability;
- Nto mount inductor nrog siab tam sim no ntsuas.
Daim ntawv thov
- Hwj chim choke rau video recorders, LCD saib, laptops, kev sib txuas lus, khoom siv, chaw ua hauj lwm automation thiab lwm yam khoom siv hluav taws xob.
- Qhov zoo tshaj plaws siv hauv cov koob yees duab digital, phau ntawv sau, PC, TV teeb, DC-DC converters, thiab lwm yam.

- Inductance ntsuas qhov ntsuas ntawm 1KHz / 0.25V; 10KHz/0.25V(SP31); 100KHz, 0.1V (SPQ).
- DC Resistance ntsuas los ntawm 502BC Ohm-meter ntawm 25 degree.
- Saturation tam sim no: tus nqi tiag tiag ntawm DC tam sim no thaum qhov inductance txo 20% ntawm nws thawj tus nqi.
- Kub nce tam sim no: tus nqi tiag tiag ntawm DC tam sim no thaum cov tub ntxhais qhov kub thiab txias yog T40 degree (Ta=25 degree ).
