The EPCOS B57500K103A1 NTC Thermistor is highly accurate and has a temperature range from -40°C to +150°C. This thermistor is intended for use in critical applications where high accuracy and reliability are required, including industrial process controls, instrumentation, control cabinet control, fire detection systems, automotive climate controls and electronic circuit protection.

EPCOS B57500K103A1 NTC thermistor is a thermally sensitive semiconductor resistor which shows a decrease in resistance as temperature increases. It is encapsulated in a compact copper case and is designed for use in dry environmental conditions. It has a wide temperature range of -55°C to +155°C and an insulation voltage of 500 V AC. The thermistor has a thermal time constant of τa water approx. 4 s and a dissipation factor of 0.4 mW/K.

The thermistor is designed for use in applications such as temperature measurement, evaporator sensor for air conditioning systems and heating systems. It features a copper case and twin cable with PVC-insulated wires with tinned ends. It can also be customized to offer alternative resistance ratings, rated temperatures, resistance tolerances, wire lengths and AWG 22, AWG 24.

For reliability, the thermistor has been tested to a variety of standards such as IEC dry heat, damp heat, coldness, vibration resistance and long-term stability. It also has an insulation resistance of 100 MΩ, test voltage of 500 V AC and rated temperature of 25/100 K.

In terms of safety, users should be aware of the cautions and warnings related to storage, mounting, and thermal stress of the thermistor. They should also take note of the symbol and terms as well as abbreviations and notes related to the thermistor.

Overall, EPCOS B57500K103A1 NTC thermistor is an excellent choice for temperature measurement and other applications requiring precise temperature control. It is highly durable, reliable and safe to use.

This NTC was used in an assembly project for an air-conditioner control unit for an Italian client.
