Frequently Asked Questions
Q1: Is ETD44 a fixed power transformer model?
No. ETD44 defines the ferrite core and mechanical platform. Actual power capability depends on topology, input voltage, switching frequency, and thermal conditions.
Q2: What information is required for quotation?
Please provide input-voltage range, converter topology, switching frequency, output voltages/currents, power requirements, isolation voltage, and applicable safety requirements.
Q3: Can primary inductance and leakage inductance be customized?
Yes. Primary inductance tolerance and leakage-inductance targets can be defined according to the converter design requirements.
Q4: What is the MOQ?
The standard MOQ is 100 pieces. Prototype and production quantities can be discussed according to project requirements.
Q5: How long does quotation and sample production take?
Quotation target is within three days after complete technical requirements. Sample production targeted within seven days after specification confirmation.
