SDQ Series
Low Profile Dual Winding
Shielded Inductor/Transformer
Description
• Dual winding inductors that can be used as either a
single inductor, or in coupled inductor/transformer
applications (1:1 turns ratio)
• Windings can be connected in series or parallel, offering
a broad range of inductance and current ratings
• Current Range from 6.43 to 0.063 Amps
• Inductance range from 0.47µH to 4.03mH
• Ferrite shielded, low EMI
• RoHS compliant (-R option)
Applications
• As a transformer: SEPIC, flyback
• As an inductor: Buck, boost, coupled inductor
• Digital cameras, CD players, cellular phones, and PDA’s
• PCMCIA cards
Packaging
• GPS systems
• Supplied in tape and reel packaging, SDQ12 (3,800,
SDQ25 (2,900) parts per reel
Environmental Data
• Storage temperature: -40°C to +125°C
• Operating temperature: -40°C to +85°C (Range is
application specific). Temperature rise is approximately
40°C at rated rms current.
• IR reflow temperature: 240°C for 30 seconds max.

1) Test Parameters: 100kHz,.0.25 Vrms 0.0Adc
Part number definition:
First 3 characters = Product code and size.
Last 3 characters = Inductance in uH. R = Decimal point. If no R is present, third
character = # of zeros.
2) Rms current for approximately ∆T of 40°C without core loss. It is recommended
that the temperature of the part not to exceed 125°C. De-rating is necessary for
AC currents
3) Peak current for approximately 30% rolloff @20°C
4) DCR limits @20°C
5) Applied Volt-Time product (V-µS) across the inductor at 100kHz necessary to
generate a core loss equal to 10% of the total losses for a 40°C temperature
rise. De-rating of the Irms is required to prevent excessive temperature rise.
