For power supply, industrial control, appliance, and EV engineers, NTC thermistors may be a low-cost component, but removing them to reduce BOM cost can create much higher failure risks.
Why Power Supply Design Requires NTC Thermistors?
Without proper NTC thermistor protection, inrush current at startup can damage rectifiers, power ICs, relays, and other sensitive components. In temperature-sensing applications, an unreliable NTC thermistor can also lead to inaccurate thermal monitoring and control.
A properly selected NTC thermistor provides:
Inrush current limiting: High resistance when cold, suppressing startup current.
Low power loss: Resistance drops as temperature rises during normal operation.
Accurate temperature sensing: Supports thermal monitoring and control in EV, industrial, and appliance applications.
