DRQ Series
Dual Winding, Shielded
Inductors/Transformer
Description
• 125C maximum total temperature operation
• 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
• Peak current ratings from 0.13 Amps to 56 Amps
• RMS current ratings from 0.128 Amps to 17.9 Amps
• Inductance ratings from 0.33µH to 4.02mH
• Surface Mount
• 200 VAC Isolation between windings
• RoHS compliant (-R option)
Applications
Packaging
• As a transformer: SEPIC, flyback
• As an inductor: Buck, boost, coupled inductor
• DC/DC converters
• VRM inductor for CPU and DDR power supplies
• Input and output filter chokes
• Supplied in tape and reel packaging, 1350 (DRQ73),
1100 (DRQ74), 600 (DRQ125), and 350 (DRQ127)
per reel
Environmental Data
• Storage temperature: -40°C to +125°C
• Operating temperature: -40°C to +125°C (Range is
application specific).
• IR reflow temperature: 240°C for 30 seconds max.

Parallel: (1,2 - 4,2) 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.

1) Open Circuit Inductance Test Parameters: 100kHz, 0.25 Vrms, 0.0 Adc
Parallel: (1,2 - 4,2) 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.
6) Turns Ratio (1-2):(3-4) 1:1
