TE and TD
Vishay Dale
Filter Inductors
Toroid
FEATURES
• Choice of encapsulated (TE) or dipped (TD) styles.
• TD style combines low cost with excellent performance
in commercial applications.
• High Q and wide selection of Q versus frequency ranges in one
small package. Large number of standard inductance values.
