扁平線大功率電感DER3218系列

Flat wire high current power inductors DER3218 series

Product description:

Assemblage design,sturdy srtucture.
High inductance, high current, low magnetic loss, low ERS, small parasitic capacitance.
Flat wire winding, achieve a low DCR.
Temperature rise current and saturation current is less influenced by environment.
Operating temperature: -25℃～125℃.
Placement form is DIP.

NOTE:

All test data is referenced to 25℃ ambient.
Irms: DC current(A) that will cause an approximate △T of 40℃.
Isat: DC current(A) that will cause Lo to drop approximate 30%.
Operating temperature range is -25℃ to 125℃.
The part temperature(ambient and temp rise) should not exceed 125℃ under worse case operating conditions.

Circuit design, component placement, PWB trace size and thickness, airflow and other cooling provision all affect the part temperature. Part temperature should be verified in the end application.
