Mundorf BH100-4,7 4.7 mH Ferrite/Aronit DrumCore Baked Varnish Coil 0.34 Ohm ±3% 18 AWG

The Mundorf BH100-4,7 is part of the MCoil BH100 series, combining a Ferrite/Aronit drum core with baked varnish winding fixation. This construction is made for reliable use in passive speaker crossover designs where consistent inductance and controlled DC resistance are important.

With 4.7 mH inductance, ±3% tolerance and 0.34 ohm DC resistance, this coil is well suited for precise work with crossover components. The 0.79 mm² solid-core OFC copper conductor, equivalent to 18 AWG with a 1.00 mm wire diameter, provides a clear and practical specification for DIY builders and repair work.

The baked varnish fixation helps keep the winding mechanically stable, while the drum core format keeps the coil compact. Its Ø40 x H37 mm size makes it easy to integrate into crossover layouts where space is limited.

Use the BH100-4,7 when you need a Mundorf drum core inductor for passive filter networks and other loudspeaker crossover builds. It fits naturally in the coils category for builders selecting values by inductance, resistance, wire gauge and tolerance.
