Suitable for push-pull, half-bridge, full-bridge, and LLC topologies
Heavily insulated construction with external shielding options
Customizable input/output voltages and power ratings
Multi-strand wire, Litz wire, copper foil, or insulated bus conductor
Insulation System
Functional, basic, supplementary, double, or reinforced insulation
Termination
PCB pins, copper tabs, cables, lugs, busbars, or custom terminals
Key Characteristics
High Power Capability: Supports high-power conversion with proper thermal management

Electrical Testing Includes:
Primary and secondary inductance
Turns ratio and winding polarity
Leakage inductance and DCR measurements
Dielectric strength and insulation resistance
Interwinding capacitance and continuity testing
Frequently Asked Questions
Q1: Is EE65 a fixed power rating?
No. EE65 identifies the ferrite core platform. Actual power capability depends on topology, input voltage, frequency, duty cycle, flux density, conductor structure, cooling conditions, insulation system, and allowable temperature rise.
Yes. Primary, secondary, and auxiliary windings can be designed according to required voltage, current, polarity, regulation, and isolation requirements.
Q4: Can EE65 support kilowatt-level applications?
EE65 can be evaluated for kilowatt-level conversion, but the model name alone does not guarantee a particular power rating. All operational parameters must be reviewed for suitability.
Q5: Can multiple secondary outputs be added?
Yes. Independent outputs, center taps, series windings, parallel windings, and auxiliary outputs can be developed according to the approved specification.
