MF-R900 Description

Short technical summary and product information.

The Bourns MF-R900 is a polymeric PTC resettable fuse designed for overcurrent protection in electronic circuits. It features a hold current of 9.00 A and a trip current of 18.00 A, with a maximum voltage rating of 30 V and a maximum fault current handling capability of 40 A. The device has a low initial resistance range of 0.005 Ohm to 0.01 Ohm and a post-trip resistance maximum of 0.02 Ohm. The time to trip at 40 A is 20 seconds maximum, and typical tripped power dissipation is 4.20 W.

 

This PTC fuse is housed in a through-hole radial leaded package with dimensions of 24.20 mm x 3.00 mm (length x width) and a height of 32.90 mm. Lead spacing is 10.20 mm. The operating temperature range is -40°C to 85°C, making it suitable for a wide variety of environments.

 

Typical applications include overcurrent protection in power supplies, battery charging circuits, and motor control systems. The device is RoHS compliant, lead free, and halogen free per Bourns definition. Note: The product image and datasheet file currently reference other MF-R series parts and should be verified for correctness.
