Features
Economical, reliable SMD inductors
Inductance range: 1.0 uH to 1000 uH
Excellent current rating in a low-profile package
High energy storage and extremely low resistance
Excellent saturating (to 9A) and continuous
current capabilities (to 6.8A)
Designed for pick and place operations
Compatible with solder reflow processes to 240°C
Applications
Industry standard, medium current inductors for
DC/DC converter supplies
Wide inductance range with medium current for
high-frequency, medium and low voltage supplies
Inductors for DC/DC conversion circuits in
notebook computer, peripheral, cellular phone,
process control,
factory automation and test industries
Useful in battery-powered and low voltage
converters
Same package size and footprint as DSS-5121
and DHC 5121 series
Environmental Specifications
Operating temperature range:
-40°C to +85°C
Storage temperature range:
-50° to +125°C
Packaging
Parts are packaged in 24 mm embossed carrier
tape per EIA-481-2
DUS-5121 is packaged 1,000 pieces per 13 reel
NOTES:
1 Open circuit inductance test at 100KHz, 0.1 Vrms, 0.0Adc
2 DCR limits at 20°C
3 Saturating DC current for approximately 20% rolloff from initial inductance
4 Continuous DC current for approximate temperature rise of 40°C from a 25°C ambient
Surface Mount Drum Core
Power Inductors: DUS-5121 Series
