E 3 7 X 4 0 1 CPN 4 7 2ME A 5M
9 Supplement Code. Field 18.
C = PET insulation with end disk (Ø50.8mm only).
M = Pb-free PVC insulation with end disk.
S = Polyolefin insulation with end disk.
8 Case Size. Fields 15, 16 and 17.
The single letter diameter code is inserted in field 15.
C = Ø50.8mm (Ø2.000”)
D = Ø63.5mm (Ø2.500”)
E = Ø76.2mm (Ø3.000”)
F = Ø89.0mm (Ø3.500”)
The double character length code is inserted in fields 16 and 17.
For lengths ≤ 99mm, insert the actual length rounded to nearest
millimeter. For lengths of 100mm or more, insert the appropriate
alpha numeric code as indicated below.
92 = 92mm (3.625”)
A5 = 105mm (4.125”)
B7 = 117mm (4.625”)
D0 = 130mm (5.125”)
E3 = 143mm (5.625”)
F5 = 155mm (6.125”)
J1 = 181mm (7.125”)
K0 = 190mm (7.500”)
M9 = 219mm (8.625”)
7 Capacitance Tolerance. Field 14.
M = ؓ20%
6 Capacitance. Fields 11, 12 and 13.
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. 4R7 = 4.7␮F; 470 = 47␮F; 471 = 470␮F;
472 = 4,700␮F; 473 = 47,000␮F ).
5 Mounting Hardware. Field 10.
N = None.
C = Three-footed clamp.
S = Stud mount. The mounting nut is not included with
stud mount orders. It must be ordered separately.
4 Terminal Type. Fields 8 and 9.
HP = High post 10-32 NF- 2B screw thread.
HL = High post M5x0.8 screw thread.
CD = UTE M5x0.8 screw thread.
CP = Low post ¹/4-28 NF-2B screw thread.
CH = High post ¹/4-28 NF-2B screw thread.
CA = Low post M6x1 screw thread.
CS = High post M6x1 screw thread.
3 DC Rated Voltage. Fields 5, 6 and 7.
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. 4R0 = 4.0VDC; 400 = 40VDC; 401 = 400VDC).
2 Series Name. Fields 2, 3 and 4.
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.
1 Capacitor Type. Field 1.
Aluminum Electrolytic Capacitor (Polar).
