This pair of 7mH air-cored inductors, wound with .5mm enamelled wire on sturdy nylon bobbins 58mm in diameter, was originally a special order for a customer. Inductors are tinned, measured, lacquered and taped. Accuracy is normally within 1%. The bobbins come with a centre hole that allows easy fixing to your board.

All my air-cored inductors are custom wound to order and are available in a wide range of sizes and values. Just ask for a quote - I can probably wind exactly what you need (air cored coils only).
