ECONO-PAC™/OCTA-PAC
®
OCTA-PAC PLUS
Power Inductors and Transformers
Description
RoHS
2002/95/EC
• 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
• 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).
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
• CTX___-__ (First three digits CTX; Second 2-3 digits =
Inductance Value; Last 1-2 digits, product size & type)
Product Size/Type
• 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)
• Solder reflow temperature: +260°C max. for 10 seconds max.
