B57153S0160M000

Overview

The B57153S0160M000 is an NTC thermistor designed for inrush current limiting, belonging to the SL15 series. It features a radial leaded package with a diameter of 16.00 mm (0.630 inches) and a steady-state current rating of 1 A. The component exhibits a resistance of 1.9 Ohms at rated current and operates within a temperature range of -55°C to +170°C.

Feature Summary

• Utilizes negative temperature coefficient characteristics to effectively limit initial surge currents during power-up sequences.
• Provides robust protection for sensitive electronic components against high transient currents in AC and DC circuits.
• Features a compact radial design suitable for standard PCB mounting applications.

Applications

• Inrush current limiting in power supply inputs
• Protection of capacitive loads in consumer electronics
• Surge suppression in industrial control systems

Procurement Notes

Verify the specific ordering code suffix to ensure compatibility with required tolerance and packaging specifications. Confirm that the thermal dissipation requirements of the target application align with the component's steady-state current rating of 1 A. Cross-reference the datasheet for precise B-parameter values and resistance tolerances to guarantee circuit performance under varying ambient conditions.

Selection Notes

Select this component based on its 16 mm diameter and 1.9 Ohm resistance value for applications requiring moderate inrush suppression. Ensure the operating environment stays within the specified -55°C to +170°C range. Consider the radial lead spacing of 7.80 mm for PCB layout constraints. Evaluate the thermal time constant to match the switching frequency of the protected circuit.

Part Context

This part belongs to the EPCOS (now TDK Electronics) SL15 series of NTC thermistors specifically engineered for inrush current limiting. The brand has a long history in passive components, formerly operating as Siemens Matsushita Components before merging into TDK. These devices are widely used in global electronics manufacturing for reliable circuit protection.
