PTCEL13R501RBE

Inrush Current Limiters (ICL) Overview

PTCEL13R501RBE is a radial Positive Temperature Coefficient (PTC) thermistor from the PTCEL13 series, manufactured by Vishay Beyschlag/Draloric/BC Components. It features a nominal resistance of 500 Ohms with a tolerance of ±30%. The component has a maximum operating temperature of +105°C and utilizes radial termination for through-hole mounting. Designed as an inrush current limiter, it employs metal glaze technology to provide reliable circuit protection against excessive current surges.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect sensitive electronic components during power-up
• Utilizes PTC thermistor technology for automatic resettable overcurrent protection
• Constructed with metal glaze composition for robust thermal stability

Inrush Current Limiters (ICL) Applications

• Inrush current limiting in power supply inputs
• Overcurrent protection for sensitive electronic circuits
• Thermal protection in consumer electronics assemblies

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific package type and lead configuration upon procurement, as radial mounting requires appropriate PCB hole spacing. Confirm that the 500 Ohm nominal resistance aligns with the system's hold current requirements. Ensure the +105°C maximum operating temperature rating meets the environmental conditions of the final application assembly.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a resettable fuse solution is required for low-voltage DC applications. The 500 Ohm initial resistance helps limit peak charging currents for capacitive loads. Consider the ±30% tolerance when designing the trip threshold margins. Verify that the radial form factor fits the available board space constraints.

Inrush Current Limiters (ICL) Part Context

This part belongs to the PTCEL13 series of PTC thermistors designed specifically for inrush current control. Unlike standard fuses, these devices recover automatically after cooling, reducing maintenance needs. The series is characterized by fast response times and high cycle life, making them suitable for frequent switching operations in modern electronic equipment.
