About this product
F0505S-1WR3 is a 1 W isolated DC-DC power module that converts a 5 V input to a 5 V isolated output. Galvanic isolation separates the input and output grounds, which helps with noise and ground loops in sensor and interface circuits. It includes short-circuit protection.

Frequently asked questions
Why choose an isolated module?
Isolation separates the input and output grounds, which reduces noise and ground loops. It is useful for sensors or interfaces that sit on a different ground reference.
Does it need external capacitors?
Follow the datasheet for recommended input and output filter capacitors, as they help stability and reduce ripple.
