FRC tus qauv (lub hom phiaj dav dav) SMD tuab zaj duab xis resistor tsim los ntawm BEC yog qhov ntau tshaj plaws, ntau yam saum npoo -mount passive tivthaiv siv nyob rau hauv hluav taws xob circuits rau precision tam sim no/voltage limiting, teeb liab division, load matching, thiab biasing-nws yog qhov nto{2}}mount counterpart mus rau hauv-qhov carbon films / 4}voltage, optimized network volts PCB los ua ke (reflow soldering) thiab compact Circuit Court tsim. Nws siv cov txheej txheem tuab zaj duab xis tiv thaiv txheej txheej los tsim cov khoom tiv thaiv.

FAQ
Q1: Dab tsi ua rau FRC series yog "thick film" resistor, thiab qhov no txawv li cas los ntawm nyias zaj duab xis resistor?
A2: Qhov sib txawv tseem ceeb yog qhov tuab thiab kev tsim cov txheej txheem tiv thaiv:
Cov yeeb yaj kiab tuab: Cov hlau oxide / cermet muab tshuaj txhuam (ruthenium oxide + iav frit) yog tshuaj ntsuam - luam tawm rau hauv cov khoom siv ceramic thiab raug rho tawm ntawm 850-950℃; laser - trimmed rau lub hom phiaj kuj. Tsawg- nqi, siab - cov txheej txheem scalable (90% ntawm SMD resistors yog zaj duab xis tuab).
Nyias zaj duab xis: Ib txheej hlau alloy (<1 μm thick) is sputtered/evaporated onto the substrate; more precise but expensive.
Q2: Puas yog FRC tus qauv SMD tuab zaj duab xis resistors tsau lossis hloov pauv tau?
A2: Lawv yog cov resistors ruaj khov - lawv cov nqi tiv thaiv tau teeb tsa thaum tsim khoom (laser-trimmed) thiab tsis tuaj yeem hloov kho hauv - Circuit Court. Hloov pauv SMD resistors (trimmers / potentiometers) yog cov khoom sib cais rau calibration / tuning.
Q3: TCR yog dab tsi, thiab dab tsi yog TCR qhov tseem ceeb rau nti resistors?
A3: TCR (Temperature Coefficient of Resistance) yog qhov kev hloov pauv ntawm qhov kev tiv thaiv ib℃Celsius kub hloov (ppm / degree=qhov chaw ib lab ib degree), qhov ntsuas ntawm temp stability. Rau lub hom phiaj dav dav SMD tuab zaj duab xis resistors:
Cov lus qhia tshwj xeeb: ± 100 ppm /℃(± 1% kam rau ua qhov) thiab ± 200 ppm /℃(± 5% kam rau ua qhov chaw).
Piv txwv li: A 1kΩ ± 100 ppm /℃resistor hloov los ntawm 0.1Ω ib℃(0.01% tsis kam hloov) - txaus rau cov qauv siv hluav taws xob (tsis muaj ultra- temp stability xav tau).
Nyias zaj duab xis resistors muaj qis dua TCR (± 10/25 ppm / degree) rau precision daim ntaub ntawv (kev kho mob, aerospace).
