MUNDORF BS140 Copper Wire Ferron Core Coil 3.9mH

The coilsMundorf BS140are high-performance coils for filtering low frequencies.

The core is composed of FERON, which undergoes heat treatment after its production.
This treatment gives it an optimal internal structure for good magnetic characteristics offering very low losses as well as a low distortion.

Their power holding capacity is also higher than for conventional ferrite core coils.
The "Backed Varnish" finish (varnish-impregnated) BS71, BS100 and BS140makes it possible to limit the vibrations and to use a maximum wire diameter for a reduced electrical resistance.

Specifications:

• OFC Copper of Purity 99.99%
