EVAL BOARD USER'S MANUAL
Attaching the DLT to your circuit
•
Make the Connection to Your Board As Close As
Possible to Where-your Actual Load Will Be Placed
•
Make the Connections to Your Board As Short As
Possible. Any Added Wire Between the DLT and the
Circuit Under Test Will Increase Inductance and
Reduce the di/dt Capability of the DLT
•
Observe the Polarity of the DLT's Connection Tabs
