**----- Start of picture text -----**<br>
In order to meet the“Derating Curve”and the “Static Characteristics” ,UHP-350 series must be installed onto an aluminum plate(or the cabinet of the same size)<br>on the bottom.The size of the suggested aluminum plate is shown as below. And for optimizing thermal performance, the aluminum plate must have an even and<br>smooth surface (or coated with thermal grease), and UHP-350 series must be firmly mounted at the center of the aluminum plate.<br>unit:mm<br>M3*4<br>450<br>450<br>3<br>**----- End of picture text -----**<br>

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
