Plug-in overheat protection PTC thermistor
SCRBH temperature-controlled PTC thermistor utilizes the characteristic that the resistance value of the PTC thermistor rises suddenly above the Curie temperature. When the ambient temperature rises abnormally, the protection circuit equipped with the PTC thermistor changes in resistance value. Connect or disconnect the circuit to protect the components.

product description
Product Overview of PTC Thermistors for Overheating Protection
SCRBH temperature-controlled PTC thermistor utilizes the characteristic that the resistance value of the PTC thermistor rises suddenly above the Curie temperature. When the ambient temperature rises abnormally, the protection circuit equipped with the PTC thermistor changes in resistance value. Connect or disconnect the circuit to protect the components.
Main parameters of SCRBH temperature control PTC thermistor
Protection temperature point TS(℃)
Rated zero power resistance value R25(Ω)
Resistance value at protection temperature (Rs, Min)
Protection temperature -15℃ Resistance value (RS-15, Max)
1. SCRBH temperature-controlled PTC thermistor series products are divided into two shapes: A-lead type, B-surface mount type
2. Protection temperature range: 60~130℃
3. Fast response time
