Ferrite Core
2 Standard Sizes
Taped and Reeled
Typical Reel Size 3000pcs
The TR series of surface mountable wound inductors was the very first of its type specifically
designed for transponder applications. Continuous product developments mean the TR range
continues to be the most effective antenna coil available for a wide choice of applications. Its length
and cross sectional area is optimised to achieve maximum sensitivity on the coils axis.
For designs such as industrial and automotive applications, that need to withstand high shock and
vibration characteristics (Higher than 1.0m drop test), high shock versions are also available.
