APPENDIX B

FSC 5910 - CAPACITORS

B.1 SCOPE

B.1.1 Scope. The following define the requirements that pertain to both commercial and military electronic devices. Where the requirements are not stated, refer to sections 4 and 5 herein. This appendix is a mandatory part of this standard. The information contained herein is intended for compliance.

This appendix establishes the marking requirements that apply to a specific FSC. These requirements are to be applied in addition to the requirements of sections 4 and 5 herein. In the event of conflict between this appendix and section 4 or 5, the appendix shall take precedence.

B.2. APPLICABLE DOCUMENTS. This section is not applicable to this appendix. B.3. GENERAL REQUIREMENTS

B.3.1 Functional marking.

B.3.1.1 Polarity. Polarized capacitors shall be marked as follows:

a. A single "+" symbol shall indicate the positive terminal on nontubular and single-ended tubular capacitors.

b. A minimum of four "+" symbols shall indicate the positive terminal on axial-lead tubular capacitors. These shall be located approximately 90 degrees apart, at a distance no greater than 25 percent of the total body length away from the positive end of the body and located so as to be readily distinguishable from other markings. Allowance shall be made for proper isolation of the "+" symbols when calculating the maximum number of characters that can be placed on the capacitor.

c. All other symbols or markings required shall be as specified in the acquisition document. B.3.2 Part identification marking.

B.3.2.1 Capacitor marking. Marking of capacitors shall conform to method I or II, as specified in the acquisition document. Characteristics and ratings shall be marked in the sequence (reading from left to right) of the columnar heading shown under "Order of Precedence" in table B-I. Other ratings and applicable codes for method II shall be as specified in the acquisition document, Where size characteristics will not accommodate all of these characteristics and ratings, marking shall be as specified in the acquisition document in the order of precedence shown by the numerical figures in table B-I.

B.3.2.2 Marking location. All marking of capacitors shall be applied to the body enclosure (excluding any supplementary insulation sleeving). Method II shall be applied starting with (or clockwise from) the "part" code (black).
