: DC current for an approximate temperature rise of 40°C without core loss. Derating is
rms
necessary for AC currents. PCB pad layout, trace thickness and width, air-flow and proximity of
other heat generating components will affect the temperature rise. It is recommended the part
temperature not exceed 125°C under worst case operating conditions verified in the end
application.
• SDH2812 = Product code and size
• xxx= Inductance value in μH, R = decimal point,
If no R is present then 3rd digit equals number of zeros.
• “-R” suffix = RoHS compliant
