JUB1P *Larger than 100 x 100

Reference to Joint heat sink

・JUB1P(based on UB100) : Recommended when one side is between 70 mm and 100 mm and the other side is 130 mm or more.

・JUB2Z(based on UB13070) : Recommended when one side is more than 100 mm and the other side is between 100 mm and 130 mm,
depending on the orientation of the fins.

* We can also produce larger sizes. Please refer to each page for size maximums and fin orientation.
