Technical content
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

- INDUCTANCE VS. CURRENT : Inductance will fall off as DC Current is increased. (See Inductance vs. Current graph).
- INDUCTANCE VS. FREQUENCY: Inductance roll-off versus Frequency approximates 3% at 1 megaHertz.
- FREQUENCY RESPONSE: Wide-band frequency response to 1 megaHertz.
- CURRENT LIMITATION: The maximum allowable currents are defined by the internal “hot-spot” temperatures which are limited to 130°C, including ambient. -35 -15 +5 +25 +45 +65 +85 +105 +125 INDUCTANCE VS.
