Product features
•
•
•
•
•
•
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 core material
ECONO-PAC’s are a lower cost version of OCTA-
PAC’s offering high saturation flux density,
Iron
powder
core material
OCTA-PAC PLUS’s 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
•
CTX___-__ -R(First three digits CTX; Second
2-3 digits = Inductance Value; Last 1-2 digits,
product size & type)
-R indicates RoHS compliant

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.
