EMC Design Kits

Würth Elektronik EMC Design Kits feature a wide range of kits created in-house for engineers to use during prototype development. These kits feature ferrites, filter chokes, and common mode chokes. The kits can be used for low-voltage applications, data and main power lines, ESD and surge protection, and EMI shielding materials. A product index of part numbers and part values is indicated in each kit, which enables users to pick and choose a part to test in designs.
