● The resistance value and B value can be determined according to customer needs.
● The injection molding appearance and wire of the end can be customized.
● The wire nose series is specially designed for negative temperature coefficient thermistor temperature sensors.
● Long-term stability and anti-drift.
● High precision resistance and B value, good consistency and interchangeability. (The tolerance of resistance value and B value can be 1%)
● High sensitivity and fast response speed.
● Good insulation, mechanical shock resistance, bending resistance and high reliability.
● High temperature measurement accuracy.
