Thermistor Element

PSB-N Thermistor

DHD (Double heatsink diode) type

A PSB-S thermistor is sealed in a DHD form. It is an axial lead type with wires coming out of both ends of the thermistor element. Heat resistance is provided by glass encapsulation. Wide-spaced lead wires contribute to lower possibilities in measurement error caused by leakage even with a high resistance thermistor chip. This enables PSB-N thermistors to be used in harsh environments such as in oil smoke, dust or humidity.

PSB-N Thermistor


  • Chip with gold electrodes
  • Suitable for use in severe environments such as oil vapor with its wide-spaced lead wires
  • Long-term stability in resistance
  • The wire diameter is large enough to support automatic mounting
