Description
3.8mm x 3.8mm shielded drum cores available in two
heights: 1.2mm and 1.4mm
Current range from 4.44 to 0.100 Amps
Inductance range from 0.47 uH to 680 uH
Ferrite shielded, low EMI
RoHS compliant (-R option)
Applications
Digital cameras, cellular phones, CD players, and PDAs
PCMCIA cards
GPS systems
Environmental Data
Storage temperature range: -40°C to +125°C
Operating ambient temperature range: -40°C to +85°C
(range is application specific). Temperature rise is
approximately 40°C at rated rms current
Infrared reflow temperature: +240°C for 30 seconds
maximum
Packaging
Supplied in tape and reel packaging,
4,150 parts per 13" reel
SD38 Series
Low Profile, Shielded Inductors
(1) Test Parameters: 100KHz, 0.100Vrms, 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.
De-rating is necessary for AC currents.
(3) Peak current for approximately 30% rolloff 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.
De-rating of the Irms is required to prevent excessive temperature rise.
