ECONO-PAC™/OCTA-PAC®
OCTA-PAC® PLUS
Power Inductors and Transformers
Description
• Surface mount magnetics that can be used as single or
coupled inductors or 1:1 transformers that provide isolation
between two windings
• OCTA-PAC’s are designed around high frequency, low loss
material
• ECONO-PAC’s are a lower cost version of OCTA-PAC’s
offering high saturation flux density
• OCTA-PAC PLUS’s offer higher current ratings and higher
saturation flux densities than OCTA-PAC and ECONO-PAC
• Secure 4 Terminal Mounting
• Inductor more versatile inductance combination by series
or parallel connections
• RoHS compliant (-R option)
Applications
• Computer and portable power devices
• LCD panels, DVD players
• Inductor: DC-DC converters
• Buck, boost, forward, and resonant converters
• Noise filtering and filter chokes
Packaging
• Supplied in tape and reel packaging, 1100 (EP01, OPA1,
and OP01), 800 (EP02, OP02, OPA2, EP03, OPA3, and
OP03), and 600 (EP04, OPA4, and OP04) per reel
Legend
Marking
• Transformers: 1:1 300Vdc isolation, flyback, sepic
• CTX___-__ (First three digits CTX; Second 2-3 digits =
Inductance Value; Last 1-2 digits, product size & type)
