Choosing how to power your design is vital, as this can alter how the product performs, its cost and where and when it can be used. You may wish to integrate the power supply circuitry into the PCB design or choose an off the shelf solution - whichever you choose, we can help with over 7,800 switch-mode and linear power supplies, with nearly 17,000 DC-DC conversion options, as well as rechargeable and non-rechargeable batteries.
Also, when you are adding circuit protection you'll find fuses, electronic circuit breakers, fuse holders and lots more. We’ve everything you need under one roof.
