Frequently Asked Questions
Is ER42 a fixed power rating?
No. ER42 identifies the ferrite core platform. Actual power capability depends on topology, input voltage, switching frequency, duty cycle, flux density, winding structure, output current, cooling conditions, and allowable temperature rise.
What information is required for quotation?
Please provide input-voltage range, converter topology, switching frequency, duty cycle, output voltages, output currents, power requirements, primary inductance, turns ratio, leakage limit, DCR limits, isolation voltage, operating temperature, cable length, terminal type, and mechanical drawing.
Can the ER42 input and output voltages be customized?
Yes. Primary, secondary, and auxiliary windings can be designed according to the required input range, output voltage, current, polarity, and regulation.
Can ER42 support multiple isolated outputs?
Yes. Multiple independent secondary and auxiliary windings can be developed. The voltage, current, isolation, polarity, and load profile of every winding should be specified.
What is the MOQ?
The MOQ shown for this ER42 product is 100 pieces. Final prototype and production quantities depend on materials, terminals, cables, construction, and project requirements.
