Toko S18 / 4.5t Variable Inductor

Popular tunable inductor from Toko with ferrite hexagonal core. In a yellow plastic former with nominal inductance of 180nH.

Cores can be interchanged between two types, ferrite and aluminium, so inductance can be varied over a large range.

These are now long obsolete, and we stock either original parts or an equivalent (which are identical in size and performance).
