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
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
• Transformers: 1:1 300Vdc isolation, flyback, sepic
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
PARALLEL
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

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) Values @ 20° C, Maximum DCR is +15% of typical value.
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 without core loss, ambient temperature of
85°C. It is recommended that the temperature of the part not exceed 125°C
4) Values @ 20° C, Maximum DCR is +15% of typical value.
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.
