Honeywell 135 Discrete Thermistors

Honeywell 135 Discrete Thermistors are robust, glass-encapsulated sensors. These thermistors feature high-temperature capability, uniform dimensions, and tape-and-reel packaging for automated assembly. The 135 series discrete thermistors operate within a temperature range from -60°C to +300°C, with a maximum nominal resistance of 5,000,000Ω and ±10% tolerance. These components are compact and durable, provide a dissipation constant of 2.5mW/°C, a time constant of 4.0s in air, and are available on tape and reel for efficient handling. Typical applications include automotive, communications, computers, consumer electronics, fire detection, and PCB temperature sensing.
