Note 1. While the NTE6218 is capable of sustaining these vertical and levered tensions, the intimate
contact between the package and heat may be lost. This could lead to thermal runaway. The
use of very flexible leads is recommended for the anode connections. Use of thermal grease
is highly recommended.

Mounting Procedure
The NTE6218 package requires special mounting considerations because of the long longitudinal axis of the copper
heat sink. It is important to follow the proper tightening sequence to avoid warping the heat sink which can reduce
thermal contact between the NTE6218 and the heat sink.
Step 1:
2−3 Turns
Locate the NTE6218 on the heat sink and start mounting
bolts into the threads by hand (2 or 3 turns).

HEAT
Step 2:
2−3 Turns
Finger tighten the center bolt. The bolt may catch on the
threads of the heat sink so it is important to make sure the
face of the bolt or washer is in contact with the surface of
the NTE6218.
