## Mechanical Specifications
Weight: 66.000 (g) per Set
## Part Type Information
The U core offers an economical core design with a nearly uniform cross-sectional area. In a power ferrite material they are frequently used in output chokes, power input filters and transformers for switched-mode power supplies and HF fluorescent ballasts.
-These U cores have the same minimum cross-sectional area as the listed effective cross-sectional area.
-AL value is measured at 1kHz, < 10 gauss.
-For any U core requirement not listed in the catalog, please contact our customer service group for availability and pricing.
-Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade.
-Weight indicated is per pair or set.
