– Some older Japanese hybrid modules or OEM-specific components (e.g., in Sony, Panasonic, or automotive ECUs) use markings like "HX-JE" without public datasheets.
Some NTC thermistors are used to limit inrush current in power supplies.
The range of temperatures over which the thermistor can operate effectively. hx-je datasheet
Thermistors come in various packages, such as SMD (Surface Mount Device), leaded, or probe assemblies. The datasheet will specify the physical dimensions and type of leads.
If you can provide a photo of the part or tell me where it came from (e.g., “voltage regulator on a 2019 LG TV motherboard”), I can help identify the real part number and locate its datasheet for you. – Some older Japanese hybrid modules or OEM-specific
Possible reasons and next steps:
The following parameters are standard for components marked (based on the HX4004A and PS3120A datasheets): Thermistors come in various packages, such as SMD
The B value is a material constant that indicates the sensitivity of the thermistor. It is used in the Steinhart-Hart equation to calculate the temperature based on the resistance.
