It features a nominal resistance of 16 Ω with ±20% tolerance at 25°C and a maximum steady-state current rating of 2.9 A. The component operates within a temperature range of -55 °C to 170 °C and has a thermal time constant of 70 s. Physical dimensions include a diameter of 11.5 mm, width of 6 mm, and length of 11.5 mm. It supports AC voltage ratings of 115 VAC and 230 VAC.

Feature Summary

• Provides effective suppression of high inrush currents during power-up phases
• Features a robust leaded and coated disk construction for PCB mounting
• Maintains stable performance across a wide operating temperature range

Applications

• Inrush current limiting in power supply circuits
• Protection of electronic equipment against surge currents
• General consumer electronics power input stages

Procurement Notes

Verify that the specific ordering suffix M051 corresponds to the required tape and reel packaging configuration rather than bulk or cut tape formats. Confirm that the 16 Ω resistance value aligns with the target circuit's impedance requirements. Ensure the 2.9 A current rating exceeds the peak inrush demands of the application. Check compliance with RoHS and REACH standards as specified in the official datasheet.

Selection Notes

Select this component based on the required 16 Ω resistance and 2.9 A current handling capability. Consider the physical footprint of 11.5 mm diameter and 6 mm width for PCB layout constraints. Evaluate the thermal time constant of 70 s against the system's recovery time needs. Verify compatibility with standard through-hole soldering processes and ensure the operating temperature range meets environmental specifications.
