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 core material
• ECONO-PAC’s are a lower cost version of OCTA-PAC’s offering high saturation flux density, Powder Iron 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

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

• INDUCTANCE VS. CURRENT : Inductance will fall off as DC Current is increased. (See Inductance vs. Current graph).
• FREQUENCY RESPONSE: Wide-band frequency response to 1 megaHer tz.
• CURRENT LIMIT ATION: The maximum allowable currents are defined by the internal “hot-spot”temperatures which are limited to 130° C, including ambient. INDUCTANCE VS.
