Huaju Electronics is a professional thermistor manufacturer. The company mainly engages in the R&D and production of thermistors, varistors, and resettable fuses. Relying on its strong R&D capabilities, the company has recently launched an overheating protection PTC thermistor, which is another flagship product of the company.

　　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

　　4. Long-term stability

　　5. Small size and easy installation

　　6. No further settings are required after the product is overheated.

　　3. Model name, appearance structure and dimensions:

　　

 

　　SCRBH appearance and structure diagram

　　

 

　　Application scope

　　1. Switching power supply

　　2. Electronic equipment (motor, transformer, etc.)

　　3. Power devices

SCRBHC motor protection PTC thermistor

Application scope:

 This product is widely used in situations where over-temperature protection is required. When the product is installed in equipment that requires over-temperature protection, the PTC resistance signal is transmitted to the motor protector. When the temperature approaches the insulation heat-resistant grade, the motor protector disconnects the circuit to implement protection.

Features:

  Made of ultra-small PTC thermistor, it has small size, long life, good stability and high sensitivity. The technical indicators have reached the international level of similar products.

use

  It can be used alone or in series to control the temperature at different points in the same circuit.

Technical data

　The control temperature range is Tk60℃～Tk180℃. The control temperature Tk is set to a specification every 5°C. One to six cores can be produced according to user requirements. The SCRBHC series adopts German DIN 44080, DIN 44081, and DIN 44082 standards.

working principle

　PTC thermistor has positive temperature coefficient resistance characteristics. When the temperature reaches its Curie point, the phase change of the semiconductor ceramic begins, and its resistance value increases rapidly with the increase of temperature. The change is especially obvious near the control temperature point Tk, thus serving the purpose of controlling the circuit.

Installation instructions:
Fix the sensor at the location where the temperature needs to be detected (usually installed in the winding). Do not knock or squeeze the sensor chip hard during installation. Do not let the lead bear tensile force. The lead is connected to the motor junction box. It must be used in conjunction with a motor protector to control motor over-temperature.
Each chip of the three-core sensor is installed at an appropriate position in the three-phase winding, with one core installed in each phase winding.
