Materials can be found in most appropriate shapes for its use: toroids for common mode chokes, cable shields, beads, rods and several ready to mount solutions like SMD beads, through hole wideband chokes and encapsulated cable shields. 3E65 Ferroxcube 3E65 is a medium permeability ferrite material optimized for Common Mode Electro Magnetic Interference (EMI) suppression. Its frequency stability allows the designer to attenuate noise over the complete conducted EMI frequency band up to 30 MHz. Increased Curie Temperature (Tc, highest temperature at which the material shows its magnetic properties) is well suited for high temperature application segments, such as automotive, industrial and renewable energies. Maximum magnetic flux density (Bsat) is also higher than in standard medium permeability ferrite materials, improving the EMI suppression capability under inrush currents or non-compensated currents. 3E65 Specifications A medium permeability material with low losses and high Tc, optimized for use in wideband transformers as well as EMI-suppression filters.

Deviations may occur due to product design (large cross section increases eddy currents thus decreasing the frequency stability) as well as process coating and tumbling. Winding with thick wire and potting influences the performance as well. 3E65 Extended bandwidth and High Curie Temperature 3E65 Popular Sizes Ferroxcube 3E65 is available in a wide variety of toroid sizes.

TC stands for Parylene coating and TX for Epoxy coating. Bare cores are available as well, then referenced as T. Product dimensions are shown as TX [Outer Diameter / Inner / Height]-3E65. Standard AL tolerance is ±20% for TX (Epoxy) and ±25% for TC (Parylene). It is also possible to produce 3E65 in planar cores to be wound with PCB windings or clamped on bus bars. Coating Properties Toroidal cores are coated to prevent isolation failures due to the high voltages present on common mode chokes.The coating material applied depends on the core size: small cores (less than 10 mm outer diameter) are coated with Parylene, while the rest are coated with Epoxy. Parylene is a conformal coating, vapor deposited polymer which provides 1000 Volts DC isolation voltage. The coating thickness is 10 to 15 µm. Parylene meets RoHS directives, and is flame retardant according to UL94 V-2. Maximum operating temperature in air is 120 deg C, but in oxygen free environments up to 260 deg C. Epoxy is a spray coating material which provides 2000 Volts DC isolation voltage with a 0.10 to 0.15 mm layer. Epoxy meets RoHS directives and is flame retardant according to UL94 V-0 class. The maximum operating temperature is 200 deg C. This material is very well suited for winding with thick copper wire due to its hardness. 5 Impedance Performance Inductive components and in particular ferrites exhibit ideal properties to attenuate EMI: their impedance increases with frequency and becomes resistive when µ’’, the complex component of ferrite magnetic permeability, is predominant over µ’. The common mode choke impedance per line can be estimated by the following formula: Ae: core effective area, le: core effective length, f: frequency, N: number of turns per line, µ0: vacuum permeability, µ’ and µ’’: real and complex material permeability. This formula gives a rough estimation because the parasitic capacitance between windings has strong impact on the high frequency performance. The plot on the right shows typical performance curves for TX25/15/10-3E65 (25 mm outer diameter, 15 inner, 10 height) wound with different number of turns. The following plots compare the performance of 3E65 on different sizes with a market standard medium permeability material: 3E65 Optimized for use in wideband transformers as well as EMI-suppression filters 3E65 Ferroxcube 3E65 outperforms other ferrite materials when it comes to tough conditions: high Tc 165 deg C makes this ferrite material suitable to operate at extreme temperatures up to 150 deg C, as requested on automotive grade 0 components. Fig. 5 impedance vs frequency Inrush currents and non-compensated phases are critical for standard common mode chokes, as they can be driven into saturation by these flux peaks. 3E65 handles up to 480 mT when standard mid-perm ferrite materials saturate at 400 – 430 mT. The plots below show how this property turns into higher current handling capability: Fig. 6 plot with impedance over freq under different H levels 7 FERROXCUBE - A GLOBAL COMPANY HQ Taipei,Taiwan Ferroxcube Taiwan Tel: +886 2 6629 9999 Fax: +886 2 6628 8886 Mail: [email protected] ASIA Europe North America Dongguan, China Ferroxcube China Elmshorn, Germany Ferroxcube Germany El Paso (TX), USA Suzhou, China Ferroxcube China Cinisello Balsamo (MI), Italy Ferroxcube Italy San Diego (CA), USA Singapore Ferroxcube South Asia Skierniewice, Poland Ferroxcube Polska Tel: +86 769 8681 8777 Fax: +86 769 8733 9561 Mail: [email protected] Tel: +86 512 6825 5568 Fax: +86 512 6825 5386 Mail: [email protected] Tel : +65 6244 7800 Fax : +65 6244 4943 Mail: sales_sa@ferroxcube Tel: +49 4121 870 199 Fax: +49 4121 870 271 Mail: [email protected] Tel: +39 02 6604 5469 Fax: +39 02 6129 1739 Mail: [email protected] Tel: +48 46 834 00 07 Fax: +48 46 834 00 35 Mail: [email protected] Guadalajara, Spain Hispano Ferritas Tel: +34 949 247 179 Fax: +34 949 247 146 Mail: [email protected] Tel: +1 915 599 2328 Fax: +1 915 599 2555 Mail: [email protected] Tel: +1 619 207 0061 Fax: +1 619 207 0062 Mail: [email protected] Phoenix (AZ), USA Tel: +1 480 821 2634 Mail: [email protected] Pittsburgh (PA), USA Tel: +1 724 602 2420 Fax: +1 724 602 2420 Mail: [email protected] For a complete listing of all Ferroxcube sales offices, distributors, and representatives, please visit "contact us" at www.ferroxcube.com © Ferroxcube International Holding B.V. 2014 All rights are reserved.
