PTCEL17R501TTE401

Inrush Current Limiters (ICL) Overview

The PTCEL17R501TTE401 is a Positive Temperature Coefficient (PTC) thermistor designed as an inrush current limiter. It features a nominal resistance of 500 Ohms with a tolerance of ±30%. The component has a maximum steady-state current rating of 40 A and withstands peak voltages up to 1 kVDC or 700 Vrms. It utilizes a radial through-hole package with a 10 mm lead spacing and measures approximately 16.51 mm in diameter.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting for electronic circuits
• Features high thermal stability within the specified operating range
• Designed for reliable protection against transient overcurrent events

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer primary side protection

Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific suffix TTE corresponds to the required lead configuration and packaging format, as variations exist within the PTCEL series. Confirm that the 500 Ohm resistance value aligns with the circuit's standby leakage current requirements. Ensure the 40 A current rating exceeds the system's maximum operational load to prevent unnecessary tripping during normal operation.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 500 Ohm initial resistance is required to limit charging currents. Verify that the 1 kVDC voltage rating meets the peak line voltage conditions. Consider the 10 mm lead spacing for compatibility with the target printed circuit board layout and mounting constraints.

Inrush Current Limiters (ICL) Part Context
