Cases AF through OA inclusive have studs and terminals on same face. Stud size and length are as sh

25、own in dimension F. 2. Dimensions are in inches. 3. Metric equivalents are given for general information only. 4. Tolerances on dimensions A and B are +.000, -.062 (+0.00, -1.57 mm) for cases AF, AG, AH, and AJ; +.000, -.125 (+0.00 -3.18 mm) for all other cases. 5. Tolerances on dimensions C are +.0

26、00, -.125 (+0.00, -3.18 mm) for cases AF, AG, AH, and AJ; +.000, - .185 (+0.00, -4.78 mm) for all other cases. 6. Tolerances on dimensions D and E are .016 (0.41 mm) for cases AJ to JB inclusive; .031 (0.79 mm) for cases KA to LB inclusive; and .047 (1.19 mm) for cases MA to OA inclusive. The center

27、lines of the drawings are the centerlines of the case; D/2 and E/2 are the reference dimensions. 7. Tolerances for cases YY and ZZ are as follows: Dimensions not exceeding those for the AJ case have the same tolerances as the AJ cases. For larger dimensions up to case size OA, the tolerances in note

28、s 4, 5, and 6 apply. For case sizes larger than OA, tolerances are as specified. Dimensions A, B, and C for ZZ cases are considered maximum dimensions (see 3.1). 8. Tolerances on dimension S for two-stud mounting are .016 (0.41 mm) for cases AF to AH inclusive. For four-stud mounting, the difference

29、 between the two diagonal S dimensions should not exceed 1.5 times the tolerance specified for dimensions D and E in note 6. 9. Screw-stud lengths are measured from the mounting surface and have a length tolerance of .062 (1.57 mm) on studs .500 (12.70 mm) long or less, and .125 (3.18 mm) on studs o

30、ver .500 (12.70 mm) long. Mounting screw inserts may be supplied instead of studs for case sizes AF, AG, and AH, or units of equivalent volume and have a minimum depth equivalent to eight full threads (grades 4, 6, and 8 only) of the same diameter as the stud of the corresponding case size. Inserts

31、meet all stud requirements. 10. Rectangular cases may have corner radii not to exceed one-quarter of the smallest envelope dimensions. 11. When mounted, tilt of units (overhand only) measured horizontally or vertically, may not exceed .016 (0.41 mm) per inch of height but need not be less than .016

32、(0.41 mm) for any height, and are referenced to the maximum specified case dimensions. 12. Templates used for verifying mounting stud dimensions are a minimum of .375 (9.52 mm) inch thick and have nominal D, E, S, and L dimensions shown for each case size. The tolerance for template dimensions D, E,

33、 and S is .001 (0.03 mm) inch, and .0005 (0.013 mm) inch for dimension L. FIGURE 1. Envelope and mounting dimensions Continued.

Dimensions are in inches. 2. Metric equivalents are given for general information only. 3. Dimensions fixing the

39、 contact pin positions refer to their fixed ends and are given for information only. Pin positions may be checked by means of alignment gauge No. GB8-1 in accordance with EIA Standard RS-209-A. For bases with coaxial lead, use gauge GB8-1 with pin 4 pin hole, .1600 .0005 (4.064 0.013 mm) diameter to

40、 a depth of 1.25 (31.8 mm) minimum. 4. Underside of base. 5. Dimension B does not include increase in pin diameter due to solder. 6. Dimension L may be increased by .030 (0.76 mm) maximum for solder. 7. Any projection on the under-surface of the base other than those shown, such as a rim or external

41、 barriers, have a height not exceeding .045 (1.14 mm). 8. Pin numbering is viewed from the pin ends. The drawing shows the numbering of the pins as seen from their free ends. 9. External mounting support required for plug in type filters having no means of support other than socket. 10. The numbers

42、indicated above each base drawing refer to the Group Number of Pin and Index Guide Dimensional Limits. FIGURE 2. Case and mounting dimensions for PA, PB, PC, PY, and PZ - Continued.
