Fast Response Speed 33D15 NTC Thermal Resistor Strong Ability To Suppress Surge Current
The most important performance of NTC negative temperature coefficient thermal sensor is life
Long-life NTC thermistor is an improvement of the understanding of NTC thermistor, emphasizing the importance of resistance life. The most important thing about an NTC thermistor is its lifespan. After withstanding various tests of high precision, high sensitivity, high reliability, ultra-high temperature, and high pressure, it still works stably for a long time.
Life is an important performance of NTC thermistor, and it has a dialectical relationship with other parameters such as precision and sensitivity. An NTC resistor product must first have a long life in order to ensure the performance of other performances; and the excellence of other performances depends on the production process reaching a certain technical level, which makes the long life of NTC possible.
Many high-tech electronic products require thermistors to perform stable temperature control and temperature measurement functions under ultra-high temperature, ultra-high pressure and other harsh conditions. Most manufacturers blindly pursue the conventional performance of NTC thermistors such as accuracy, sensitivity, and drift value. The stable performance of the resistor ignores the life of the resistor, which affects the use of electronic products due to the inability of the NTC to work for a long time. In this way, all the accuracy, sensitivity, high temperature resistance, etc., become meaningless.
Applications:
Can be installed into the power circuits of:
• Power supplies and inverters
• Uninterruptible Power Supplies
• Energy saving lamps
• Electronic Ballasts
• Filament Protection of various types of lamps
• Some types of heaters
• For higher power circuits ask about the MF73 and MF74 series surge suppressors.
