MULTILAYER INDUCTORS
Our range of multilayer inductors offers magnetic
shielding, in five standard sizes (0402, 0603, 0805,
080505 and 1206), which are specially designed for
miniaturized electronic products. It offers minimum flux
leakage thus eliminating cross talk. They have
inductances between 1 nH and 18 mH.
Multilayer inductors
Features
•
Monolithic structure for closed magnetic path and high
reliability.
•
Standard EIA and EIAJ sizes: 0402, 0603, 0805,
080505, 1206.
•
This multilayer chip inductor results in magnetic
shielding: the absence of leakage flux makes it most
suitable for high density mounting.
•
Suitable for wave and reflow soldering.
•
Plating material lead-free
•
Wide range of inductance values.
•
Superior physical properties.
•
Available in standard EIA and EIAJ tape-and-reel.
•
Operating temperature -40ºC to +125ºC.
•
100% sorting out on inductance.Product construction
Main applications areas for multilayer inductors are:
•
computer and peripheral equipment: mother board,
notebook, CD-Rom, DVD-Rom, CD-RW, scanner, hard
disc, VGA card, sound card, LCD monitor, printer, PC
server thumb drive, PCMCIA card, graphic card, etc.
•
network: LAN card, hub, switcher, router set top box,
etc.
•
telecom: cell phone, ADSL, wired modem, cable
modem, ISDN, GPS satellite receiver, etc.
•
consumer: walkman, walkdisc, digital still camera
(DSC), sound system, HDTV, projector, DVD player,
VCD player, tuner for TV, cable modem, etc.
Main high frequency application for multilayer inductor
MLH are:
•
cell phone, dect phone, wireless LAN card, wireless
micro-phone, TV tuner, RF receiver, cable modem, RF
amplifier, security remote control, wireless mouse,
wireless keyboard pager, set top box.
To help designers in the trial and error process of finding
the most suitable component, we offer a sample box with
a selection of products.
