This product is a Negative Temperature Coefficient (NTC) thermistor designed for various electronic applications. It is suitable for use in switching power supplies, electronic energy-saving lamps, electronic ballasts, and other electronic circuits. The thermistor offers a rated zero-power resistance value with specified accuracy and a maximum steady-state current.
| Model | Size | Rated Zero-Power Resistance () | Tolerance (%) | Max. Steady-State Current (A) | Environment Temperature (C) | Test Power (mW) | Thermal Time Constant (s) | Dissipation Factor (mW/C) | Rated Power (mW) | Allowable Operating Current (mA) |
| 4032(D-11) | 4032 | 100 | 10 | 100 | 25 | 1 | 20 | 10 | 100 | 100 |
Note on Resistance Measurement: Resistance values are measured at ambient temperatures of 25C or 70C.
Note on Thermal Time Constant: This is the time required for the thermistor element's temperature to change from its initial temperature to a final temperature difference, under zero-power conditions, when the ambient temperature changes abruptly. Typically measured in seconds.
Note on Dissipation Factor: This is the power required to raise the thermistor's temperature by 1C due to self-heating at a specific ambient temperature. Typically expressed in mW/C. Can be calculated using the formula: Dissipation Factor = Rated Power / Temperature Rise.
Note on Rated Power: This is the power required to raise the surface temperature by 1C due to self-heating at an ambient temperature of 25C.
Note on Allowable Operating Current: This is the current that causes a temperature rise of 1C due to self-heating in still air.
Important Note: Do not allow the soldering iron tip to contact the terminal end.
