NTCLE350 is suitable for EGR applications (exhaust gas recirculation) for steady state temperatures going up to 185 °C. This series is also intended for oil temperatures sensors (OTS), in for example transmission systems and liquid cooled starter/generator systems. The AEC-Q200 qualification (between -55 °C and 185 °C) enables this series to be used for classical motor thermal sensing applications (engine coolant, fuel sensor, TMAP for manifold air pressure) as well as in HVAC applications. 30 mg Resistance value at 25 °C Tolerance on R25-value B25/85-value Response time (63.2 %) in stirred air 25 °C to 85 °C (for information only) Weight DESIGN-IN SUPPORT Not intended for fluid immersed applications or continuous contact with water or conducting liquids. See also Environmental Conditions. Can be potted in suitable resins.

Ø d1 2.4 max. 2.4 max. 40 ± 1 6±1 5±1 0.4 0.2 ± 0.02 MOUNTING The thermistors are suitable for all standard assembly processes like crimping, brazing, and welding (laser, ultrasonic, or resistance). The parameters of the assembly process should be chosen in accordance with the lead-wire material (silver plated Ni-Fe alloy) and validated in application. Different conductor, insulation material, and dimensions are available on request. The mounting process should be in compliance with the following guidelines and recommendations: • Peeling forces on the leads should be reduced to a minimum and should never exceed 3 N • Avoid large temperature gradients between the welding region and the sensor • After complete assembly it is recommended to fix the leads in the welding region with a strain relief If using a ceramic adhesive / potting or filling material avoid phosphate-based binders. Always follow the supplier’s curing specifications fully including bringing the part up to operating temperature for a short time to ensure good moisture resistance and electrical performance of the total sensor. ENVIRONMENTAL CONDITIONS The thermistor should not be placed in a reducing atmosphere or be subjected to corrosive substances (e.g. phosphates) which could affect the functionality or the lifetime of the thermistor. Always maintain a sufficient partial oxygen pressure to avoid abnormal electrical drift and / or a reduced “life time”. The thermistor design can withstand conditions with low concentrations of H2S, NO2, Cl2, and SO2 according to DIN EN 60068-2-60, test Ke, method 4. Additionally it can withstand FOS90 testing according to ASTM B 809-95 (1000 hours / 90 °C / 76 % to 95 % RH / sulfur flowers) and 12 hours immersion (at 50 °C) in low concentrations of HCl, H2SO4, and acetic acid without functional or visual damage. The thermistor was qualified according to AEC-Q200 rev. D with top temperature of 185 °C to assure best performance in today’s most challenging environments.
