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). • Solder reflow temperature: +260°C max. for 10 seconds max. 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) PARALLEL Part Number CTX0.47-1P-R CTX0.68-1P-R CTX1-1P-R CTX2-1P-R CTX5-1P-R CTX8-1P-R CTX10-1P-R CTX15-1P-R CTX20-1P-R CTX25-1P-R CTX33-1P-R CTX50-1P-R CTX68-1P-R CTX100-1P-R CTX150-1P-R CTX200-1P-R CTX300-1P-R CTX0.47-2P-R CTX0.68-2P-R CTX1-2P-R CTX2-2P-R CTX5-2P-R CTX8-2P-R CTX10-2P-R CTX15-2P-R CTX20-2P-R CTX25-2P-R CTX33-2P-R CTX50-2P-R CTX68-2P-R CTX100-2P-R CTX150-2P-R CTX200-2P-R CTX300-2P-R Open Circuit Inductance µH +/-20% .42 .60 1.07 2.02 4.83 8.08 9.62 15.03 20.46 25.40 32.33 50.52 68.40 99.01 150.72 198.41 299.87 .54 .85 1.22 2.18 4.90 7.65 9.83 14.99 19.58 24.79 32.67 49.10 68.85 99.14 148.10 201.59 300.42 Full Load Inductance µH min. .31 .43 .73 1.36 3.37 5.31 6.23 9.62 14.12 17.07 22.27 33.57 43.65 63.64 96.64 130.79 190.05 .42 .64 .89 1.56 3.57 5.31 6.73 10.51 13.37 16.60 21.29 35.31 47.93 69.56 100.07 138.49 197.52 SERIES Full Load Current Adc DC Resistance ohms max. 5.50 5.10 4.50 3.40 2.00 1.80 1.70 1.40 1.00 .96 .80 .70 .66 .54 .44 .36 .32 5.90 5.40 5.00 3.90 2.50 2.30 2.10 1.60 1.50 1.40 1.30 .82 .76 .62 .56 .46 .42 .005 .006 .008 .013 .040 .052 .057 .087 .158 .177 .250 .316 .373 .557 .844 1.208 1.525 .006 .007 .008 .014 .032 .040 .045 .085 .097 .109 .126 .305 .362 .541 .665 .951 1.176 Open Circuit Inductance µH +/-20% 1.67 2.40 4.28 8.08 19.31 32.33 38.48 60.12 81.83 101.60 129.32 202.07 273.61 396.06 602.87 793.65 1199.46 2.18 3.40 4.90 8.70 19.58 30.60 39.30 59.98 78.34 99.14 130.70 196.38 275.40 396.58 592.42 806.34 1201.70 Full Load Inductance µH min.
