Wondering which [G1225 Series](https://www.digikey.com/short/d9vbnrbm) fan from [Mechatronics](https://www.digikey.com/en/supplier-centers/mechatronics) will best suit your application? All those part numbers can be confusing, however with this breakdown you can determine what all those numbers mean. For example, what is the difference between [G1225E24B-FSR](https://www.digikey.com/en/products/detail/mechatronics-fan-group/G1225E24B-FSR/5424780) and [G1225E24B-FSR-EM](https://www.digikey.com/en/products/detail/mechatronics-fan-group/G1225E24B-FSR-EM/8119994)? By looking at the part number breakdown we can see that the EM suffix indicates the fan has an IP57 encapsulated motor.
