d. Store devices in conductive foam or carriers.
e. Avoid use of plastic, rubber, or silk in MOS areas.
f. Maintain relative humidity above 50 percent, if practical.
g. Care shall be exercised, during test and troubleshooting, to apply not more than maximum rated voltage to any lead.
h. Gate must be terminated to source, R
100 k, whenever bias voltage is to be applied drain to source.
3.6 Electrical performance characteristics. Unless otherwise specified herein, the electrical performance characteristics are as
specified in 1.3, 1.4, and table I.
3.7 Electrical test requirements. The electrical test requirements shall be the subgroups specified in 4.4.2 and 4.4.3.
3.8 Qualification. Devices furnished under this specification shall be products that are authorized by the qualifying activity for listing
on the applicable qualified products list before contract award (see 4.2 and 6.2 ).
4. VERIFICATION
