NTPA7220LB1A0

Inrush Current Limiters (ICL) Overview

The NTPA7220LB1A0 is an NTC thermistor designed for inrush current suppression. It features a nominal resistance of 22 Ohms with a tolerance of ±15%. The component supports a maximum steady-state current of 1 A and has a body diameter of 7 mm (0.276 inches). This radial leaded device is classified as an Inrush Current Limiter within the Murata NTP series, providing reliable protection against surge currents during power-up phases.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high inrush currents during initial power application to protect downstream circuitry.
• Utilizes negative temperature coefficient characteristics to automatically reduce resistance as operating temperature increases.
• Designed for robust performance in radial leaded package configurations suitable for through-hole mounting.

Inrush Current Limiters (ICL) Applications

• Power supply input stages requiring surge current limitation
• Consumer electronics power entry circuits
• Industrial control system power modules

Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific order matches the NTPA7220LB1A0 designation to ensure correct 22 Ohm resistance and 1 A current rating. Confirm the radial leaded package style aligns with the target PCB layout requirements. Check RoHS compliance status if environmental regulations apply to the final assembly process.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 22 Ohm initial resistance is required to limit peak inrush current to safe levels for the specific load. Ensure the 1 A continuous current rating exceeds the operational load current. Consider the 7 mm body size for adequate spacing and thermal dissipation within the enclosure design constraints.

Inrush Current Limiters (ICL) Part Context

This part belongs to the NTP series of NTC thermistors manufactured by Murata Electronics. These components are specifically engineered for inrush current limiting applications rather than general temperature sensing. The series offers various resistance values and current ratings to suit different power supply designs.

Inrush Current Limiters (ICL) Replacement Considerations

Consult official Murata documentation for direct cross-references. Verify that any substitute maintains identical 22 Ohm resistance, 1 A current capacity, and 7 mm form factor to ensure circuit compatibility.
