Eaton's UNI-PAC (UP) power inductors use ferrite core material in a drum core construction with several options to choose from. The UP family products (1B, 2B, 3B, 4B) have maximum power density and are ideal for applications requiring low inductance and high current in a miniature package. Current values range from 0.28 A to 52 A. Inductance values range from 0.47 uH to 1000 uH. The UP family can be used in several applications, depending on your specific requirements.
