NTPAA2R2LD6A0

Inrush Current Limiters (ICL) Overview

The NTPAA2R2LD6A0 is a radial leaded Negative Temperature Coefficient (NTC) thermistor designed for inrush current limiting applications. Manufactured by Murata Electronics, this component features a nominal resistance of 2.2 Ohms with a tolerance of ±15%. It supports a continuous current rating of 3.7 Amperes and withstands voltage ratings up to 264 VAC. The device operates within a temperature range of -20°C to +160°C and utilizes a 10 mm diameter body with 0.8 mm leads spaced at 7.5 mm. Packaged in reels or cut tape, it serves as a robust protection element for electronic circuits.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high initial surge currents during power-up sequences
• Utilizes negative temperature coefficient characteristics to reduce resistance as temperature rises
• Features radial leaded construction suitable for standard printed circuit board mounting

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Consumer electronics AC/DC adapters
• Industrial control systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific package configuration required for your assembly line, as this component is available in both reel and cut tape formats. Confirm that the 10 mm body size and 7.5 mm lead spacing fit your PCB footprint constraints. Ensure the 3.7 A continuous current rating meets the operational requirements of your target application without exceeding thermal limits.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low-resistance inrush limiter is needed for moderate current applications. The 2.2 Ohm value offers a balance between surge suppression and steady-state power loss. Consider the ±15% tolerance for circuit design margins. Verify compatibility with the 264 VAC rating if used in mains-connected devices. Compare against higher current variants if system demands exceed 3.7 Amperes.
