SCOPE 1.1 Scope. This drawing describes the requirements for a 0.030 by 0.020 chip resist
6、or, which is resistant to the degrading effects of moisture while under power. 1.2 Part or Identifying Numbers (PINs). The complete PINs are shown in the examples below. The first example is for general military applications. (NOTE: This PIN is the original PIN shown in previous revisions of this dr
7、awing). The second example is for space type applications and requires adding a code letter to the end of the original PIN.

17、ected to this test shall not be delivered on the contract or order. 3.3.9 Outgassing (space levels A and T). Outgassing shall be performed as specified in MIL-PRF-55342. 3.4 Marking. Marking is not required on the resistor; however, each unit package shall be marked with the PIN assigned herein (see
18、 1.2), vendor CAGE code, and date and lot codes. 3.5 Manufacturers eligibility (military applications).
