Detailed Specifications For Series SME
• Miniature
• General Purpose
• Solvent Proof
• +85°C Maximum Temperature

The SME series capacitors are our standard general purpose capacitors. These radial lead capacitors are available in a wide range of voltage and capacitance ratings and are designed for a load life of 2,000 hours at 85°C with an operating temperature range of -40°C to +85°C.

The SME series capacitors, except for those rated at 350-450 volts, were developed to withstand HCFC cleaning agents for five minutes by ultrasonic, vapor or immersion. This solvent proof design allows all circuit board components to be cleaned together, at the same time, without resorting to more expensive epoxy end-sealed capacitors. Refer to the Mini-Glossary for recommended cleaning conditions.

DC Rated Voltage Test Time Leakage Current (µA)
6.3-100V After 1 minute I = 0.03CV or 4µA, whichever is greater.
6.3-100V After 2 minutes I = 0.01CV or 3µA, whichever is greater.
160-450V After 1 minute CV <=1,000: I = 0.1CV + 40 CV >1,000: I = 0.04CV + 100
160-450V After 5 minutes CV <=1,000: I = 0.03CV + 15 CV >1,000: I = 0.02CV + 25

Where I = Leakage current (µA), C = Nominal capacitance (µF) and V = Rated voltage (V)
