• Manufacturer Part Number: B57238
• Description: Inrush current limiters
• Manufacturer: EPCOS

Operation
Please read Important notes and
Cautions and warnings at the end of this document.
Inrush current limiters
ICLs
Use thermistors only within the specified operating temperature range.
Use thermistors only within the specified voltage and current ranges (ICLs).
Environmental conditions must not harm the thermistors. Use thermistors only in normal
atmospheric conditions.
Contact of NTC thermistors with any liquids and solvents should be prevented. It must be
ensured that no water enters the NTC thermistor (e.g. through plug terminals). For
measurement purposes (checking the specified resistance vs. temperature), the component
must not be immersed in water but in suitable liquids (e.g. Galden).
Avoid dewing and condensation.
Be sure to provide an appropriate fail-safe function to prevent secondary product damage
caused by malfunction (e.g. use VDR for limitation of overvoltage condition).
