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)
Product Size/Type
Environmental Data
• Storage temperature range: -40°C to +125°C
• Operating ambient temperature range: -40°C to +85°C
(range is application specific).
• Infrared reflow temperature: +240°C for 30 seconds
maximum
• CTX___-1 (-1 = size; no suffix = OCTA-PAC®)
• CTX___-1P (-1 = size; P suffix = ECONO-PAC™)
• CTX___-1A (-1 = size; A suffix = OCTA-PAC® PLUS)

1) Open Circuit Inductance Test Parameters: 100kHz, 0.250 Vrms, 0.0 Adc
Parallel: (1,4 - 3,2) Series: (1 - 3) tie (2 - 4)
2) Peak current for approximately 30% roll-off
3) RMS current, delta temp. of 40° C ambient temperature of 85° C
4) DCR @ 20°C
5) Hipot rating: winding to winding: 300Vdc min.
6) Turns Ratio: (1-2):(4-3) 1:1
7) Applied volt-time product (v-us) across the inductor. This value represents the
applied V-us at 300KHz necessary to generate a core loss equal to 10% of the
total losses for a 40°C temperature rise.

1) Open Circuit Inductance Test Parameters: 100kHz, 0.250 Vrms, 0.0 Adc
Parallel: (1,4 - 3,2) Series: (1 - 3) tie (2 - 4)
2) Peak current for approximately 30% roll-off
3) RMS current, delta temp. of 40° C ambient temperature of 85° C
4) DCR @ 20°C
5) Hipot rating: winding to winding: 300Vdc min.
6) Turns Ratio: (1-2):(4-3) 1:1
7) Applied volt-time product (v-us) across the inductor. This value represents the
applied V-us at 300KHz necessary to generate a core loss equal to 10% of the
total losses for a 40°C temperature rise.
