U787D Series

Engineering Bulletin Mar 07

C = PET sleeve, SnPb terminal plating.

The single letter diameter code is inserted in field 15.

The double digit length code is inserted in fields 16 and 17.

29 = 1.125” (29mm )

35 = 1.375” (35mm )

41 = 1.625” (41mm )

54 = 2.125” (54mm )

67 = 2.625” (67mm )

79 = 3.125” (79mm )

92 = 3.625” (92mm )

M=

20%

Expressed in Microfarads. The first two digits are significant

figures inserted in fields 11 and 12, and the third digit inserted

in field 13 indicates the number of zeros for capacitance of

10 F or more. R indicates the decimal point for capacitance

less than 10 F (e.g. 1R8 = 1.8 F; 180 = 18 F; 181 = 180 F;

182 = 1,800 F; 183 = 18,000 F).

S = 3 straight leads, 0.250” (6.3mm ) in length.

X = 3 formed leads, 2 radial and 3rd lead axial.

VG = 3 lead keyed polarity radial, vertical mount.

VT = 3 formed lead axial, horizontal mount.

Expressed in Volts. The first two digits are significant figures

inserted in fields 5 and 6, and the third digit inserted in field 7

indicates the number of zeros for rated voltage of 10VDC or

more. R indicates the decimal point for rated voltage less than

10VDC (e.g. 6R3 = 6.3VDC; 630 = 63VDC; 631 = 630VDC).

Enter the 3-letter/digit series name in fields 2, 3 and 4. If the

series name is only 2 letters/digits, place a dash in field 4.

For a series name with more than 3 letters/digits, refer to the

individual series for the appropriate 3-field series name.
