DRQ Series
Dual Winding, Shielded Inductors/Transformer
Description
• 125°C maximum total operating temperature
• Dual winding inductors that can be used as either
a single inductor, or in coupled inductor/transformer applications
(1:1 turns ratio)
• Four sizes of shielded drum core inductors
• Windings can be connected in series or parallel, offering a broad
range of inductance and current ratings

1) Open Circuit Inductance Test Parameters: 100kHz, 0.25 V rms , 0.0 Adc
Parallel: (1,2 -4,3) Series: (1-4) tie (2-3)
2) RMS current for an approximate T of 40°C without core loss. It is recommended that the
temperature of the part not exceed 125°C.
3) Peak current for approximately 30% roll-off at 20°C
4) DCR limits @ 20°C
5) Applied Volt-Time product (V-µS) across the inductor. This value represents the applied V-µS
at 100KHz necessary to generate a core loss equal to 10% of the total losses for a 40°C
temperature rise.
