Uninterruptible Power Supplies (UPS): The sensing element ensures that high-voltage power electronics maintain stability between the forward blocking and saturation operating states.
The NTC in an IGBT module is a specialized thermal sensor used to track the temperature of the semiconductor substrate in real time. Because the IGBT combines the advantages of a MOSFET’s high input impedance and a GTR’s low saturation voltage, it handles significant power density which generates substantial heat. The NTC thermistor is typically placed close to the IGBT chips to monitor temperature fluctuations. As the temperature rises, the NTC’s resistance drops, providing a signal to the drive circuit to adjust the gate-to-emitter voltage or trigger protection protocols. This prevents the turn-on voltage from drifting too far and protects the module from damage during high-current switching, ensuring the device maintains its unmatched overall performance.
Q: How does the IGBT Uses MELF Patch Glass Sealed NTC Thermistor handle temperature drift?
A: The sensor is calibrated to account for the IGBT's natural characteristic where the turn-on voltage decreases by 5mV per 1°C. By providing precise resistance changes, it allows the control system to compensate for these thermal shifts instantly.
Q: How does X-Meritan ensure the quality of thermistors for our partners?
A: Every component is manufactured in our specialized facility using automatic printing and reflow soldering equipment. We implement a full quality traceability system and adhere strictly to ISO9001, RoHS, and REACH standards to meet international reliability requirements.
Q: Why is the MELF glass-sealed package better than standard epoxy coatings?
A: Glass sealing offers a hermetic barrier that epoxy cannot match. It prevents moisture intrusion and oxidation of the NTC element, which is vital for the long-term reliability of power electronics operating in high-temperature saturation regions.
