B57153S0150M000

Overview

The B57153S0150M000 is a negative temperature coefficient (NTC) thermistor designed for inrush current limiting applications. Manufactured by TDK under the EPCOS brand, this component features a nominal resistance of 15 Ω with a tolerance of ±20% at 25°C. It has a maximum rated power of 1.4 W and a thermal time constant of 30 seconds. The device operates within a temperature range of -55 °C to 170 °C. Physical dimensions include a height of 13 mm, a length of 8.5 mm, and a depth of 6 mm. It utilizes wire termination with tin-plated copper leads.

Feature Summary

• Designed specifically for limiting inrush currents in electronic circuits.
• Utilizes NTC material properties to provide high initial resistance that decreases as temperature rises.
• Constructed with tin-plated copper leads for reliable electrical connection.

Applications

• Inrush current limiting in power supply inputs
• Protection of electronic components during startup phases
• General circuit protection against surge currents

Procurement Notes

Verify the manufacturer part number B57153S0150M000 against official TDK or EPCOS documentation to confirm specifications.
