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.

Features

• 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

*Unless otherwise stated, all thermal time constants and dissipation constants are measured in still air.
