For standard use and stand-by:

• Excellent shelf life (10 years)
• Extremely low self-discharge (1 % or less per year)
• Suited for long-term use with low current
• For operation at low current levels with long stands
• Intermittent discharge with medium current level provided the average is not below the active current level
• Temperature range from -55 °C to +85 °C

For extended temperature range:

• Extension of temperature range up to +130 °C
• Somewhat smaller capacity
• Otherwise like the SL-300 series

For enhanced start:

• Major improvement of voltage delay at the start of discharge at medium current levels (TMV)
• Intermittent discharge at medium current levels
• Best results if used after no more than 3 years of storage
• Otherwise like the SL-300 series

For fast voltage recovery after long term storage and/or use:

• Higher voltage under pulse load even with low background currents
• Improved voltage delay behaviour at ambient and elevated temperatures
• Fast voltage recovery after long term storage
• More capacity
• Higher discharge rate
• No orientation effect

For eXtended Operation Life (XOL):

• More capacity
• Extra low self discharge
• Extra low passivation during long term use

These series are generally sold in the US market but are available in Europe. Many can be replaced by an SL equivalent, please contact us for availability and advice.
