ECONO-PAC/OCTA-PAC
OCTA-PAC PLUS
Power Inductors and Transformers
Description
RoHS
2002/95/EC
Surface mount magnetics that can be used as single
or coupled inductors or 1:1 transformers that provide
isolation between two windings
OCTA-PACs are designed around high frequency, low loss core
material
ECONO-PACs are a lower cost version of OCTA-PACs
offering high saturation flux density, Powder Iron core material
OCTA-PAC PLUSs offer higher current ratings and higher
saturation flux densities than OCTA-PAC and ECONO-PAC,
Amorphous metal core material
Secure 4 Terminal Mounting
Inductor more versatile inductance combination by series or
parallel connections
Applications
Packaging
Computer and portable power devices
Supplied in tape and reel packaging, 1100 (EP01, OPA1, and
LCD panels, DVD players
OP01), 800 (EP02, OP02, OPA2, EP03, OPA3, and OP03),
Inductor: DC-DC converters
and 600 (EP04, OPA4, and OP04) per reel
Buck, boost, forward, and resonant converters
Legend
Noise filtering and filter chokes
Marking
Transformers: 1:1 300Vdc isolation, flyback, sepic
