MF72-005D7 is listed in the Inrush Current Limiters (ICL) range at ChipApex. The manufacturer field lists Cantherm. Its product description is ICL 5 OHM 20% 2A 9MM. Review the specifications below when checking this part for your BOM.
The Cantherm MF72-005D7 is a Negative Temperature Coefficient (NTC) thermistor designed as an inrush current limiter (ICL). It features a nominal resistance of 5 Ohms with a tolerance of ±20% at 25°C. The component supports a maximum steady-state current of 2 A and exhibits a low residual resistance of 120 mOhms. Its physical dimensions include a diameter of 0.354 inches (9.00mm) and a lead spacing of 0.295 inches (7.50mm).
Verify the specific manufacturer datasheet for the MF72 series to confirm electrical characteristics and mechanical dimensions. Ensure the selected component meets the required steady-state current and resistance specifications for the target application. Check RoHS compliance status if environmental regulations apply to the end product.
Select this component based on the required nominal resistance and maximum steady-state current ratings. Consider the physical package size and lead spacing for PCB layout compatibility. Evaluate the thermal response time and B-value requirements for the specific temperature sensing or limiting application.
This part belongs to the MF72 series of power NTC thermistors manufactured by Cantherm. The series is specifically engineered to curb surge currents that occur when circuits are initially powered on, thereby preventing damage to downstream components.
Public confirmed substitute part numbers: B57211P0059M301 (TDK), BN-LG13Y5R0MYB (Bourns Inc.), SL125R005 (Vishay Ametherm).
