High Power Density,
Low Profile, Shielded Inductors
Description
• Six sizes of shielded drum core inductors with low
profiles (as low as 1.0mm) and high power density
• Inductance range from .47uH to 1000uH
• Current range from 6.00 to 0.088 Amps
• Ferrite shielded, low EMI
Applications
• Digital cameras, CD players, cellular phones, and PDAs
• PCMCIA cards
• GPS systems
Environmental Data
• Storage temperature range: -40C to +125C
• Operating ambient temperature range: -40C to +85C
(range is application specific). Temperature rise is
approximately 40C at rated rms current
• Infrared reflow temperature: +240C for 30 seconds
maximum
Packaging
• Supplied in tape and reel packaging, 3800 (SD10, SD12
and SD18), 2900 (SD20 and SD25), and 3500 (SD52)
per reel

(1) Open Circuit Inductance Test Parameters: 100KHz, 0.25Vrms, 0.0Adc.
(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 approximate 30% roll off at 20°C.
(4) DCR limits @ 20°C.
5) Applied Volt-Time product (V-uS) across the inductor at 100kHz necessary to
generate a core loss equal to 10% of the total losses for 40°C temperature rise.

(1) Open Circuit Inductance Test Parameters: 100KHz, 0.25Vrms, 0.0Adc.
(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 approximate 30% roll off at 20°C.
(4) DCR limits @ 20°C.
5) Applied Volt-Time product (V-uS) across the inductor at 100kHz necessary to
generate a core loss equal to 10% of the total losses for 40°C temperature rise.
