The SMH series capacitors are the standard 85 C, large capacitance, snap-in capacitors from United
Chemi-Con. The load life for the SMH series is 2,000 hours at 85 C with the rated ripple current
applied. The very high CV values and ripple current capabilities make these capacitors ideal for use in
power supply filter circuits. The SMH capacitors are available in 2 or 4-pin snap-in styles and 3, 4 or
5-pin straight terminals with or without standoffs.
The standard SMH capacitors are non-solvent proof and are not recommended when halogenated
cleaning solvents are used. Refer to the Mini-Glossary for recommended cleaning conditions.

T2
Terminal Code: T2 = 2 - Pin Snap-in (Standard except for
Ø
40 models).
Case Code: See Case Sizes in Tables.
Capacitance Tolerance: M = 20%
Capacitance Value: Expressed in Microfarads. The first two digits are
significant figures, and the third digit indicates the number of zeros
for capacitance of 100 F or more. R indicates the decimal point for
capacitance less than 100 F (e.g. R47 = .47 F; 4R7 = 4.7 F;
47R = 47 F; 471 = 470 F; 472 = 4,700 F; 473 = 47,000 F ).
Lead Configuration: VN or VS = Snap-in Terminals.
VR = Straight Pins with or without Standoffs.
