B57234S0600M051

Overview

The B57234S0600M051 is an NTC thermistor inrush current limiter (ICL) from the S234 series by TDK. It features a nominal resistance of 60 Ohms with a tolerance of ±20% at 25°C. The component supports a maximum steady-state current of 4 A and has a diameter of 0.591 inches (15.00 mm). It operates within a temperature range of -55°C to +170°C and is available in reel or cut tape packaging.

Feature Summary

• Provides effective inrush current limiting for electronic circuits
• Ensures high long-term stability in high-temperature and humidity environments
• Offers precise temperature sensing capabilities due to tight resistance and B-value tolerances

Applications

• Smartphones and mobile devices
• Compact tablets

• LED modules
• Industrial equipment

Procurement Notes

Verify the specific ordering suffix to confirm package type, as variations exist between reel and cut tape formats. Ensure the selected variant matches the required resistance tolerance and current rating for the target application circuit. Confirm RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component based on the required 60 Ohm initial resistance and 4 A steady-state current capacity. Consider the physical dimensions of the 15.00 mm diameter for PCB layout constraints. Evaluate the operating temperature range requirements against the specified -55°C to +170°C limits to ensure reliable performance under expected thermal conditions.

Part Context

This part belongs to the EPCOS SMD NTC thermistor family, designed for temperature measurement and compensation. These components are characterized by their robust construction and suitability for demanding environments. The S234 series specifically targets applications requiring reliable inrush current protection in compact form factors.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Verify compatibility with alternative ICLs by matching resistance values, current ratings, and physical dimensions before substitution.
