Frequently Asked Questions
Q1: Is T250 a fixed inductance or current rating?
No. T250 identifies the product platform. Final performance depends on selected core material, winding conductor, turn count, frequency, and cooling conditions.
Q2: What information is required for quotation?
Please provide target inductance, rated RMS current, peak current, switching frequency, maximum DCR, working voltage, temperature-rise limit, and annual demand.
Q3: Can the inductance be customized?
Yes. Inductance can be adjusted through core material, turn count, and magnetic path construction.
Q4: Can the T250 be designed for high DC current?
Yes. Core material, conductor cross-section, and saturation margin can be selected for required DC current applications.
Q5: What is the difference between rated current and saturation current?
Rated current is limited by temperature rise and acceptable loss. Saturation current is when inductance decreases to a specified percentage of initial value.
