Mundorf BL71-0,47 0.47 mH MCoil AirCore Baked Varnish Coil 0.58 Ohm 2% 21 AWG

The Mundorf BL71-0,47 belongs to the MCoil BL AirCore Baked Varnish range and is designed for use in passive crossover components. With its 0.47 mH inductance and tight ±2% tolerance, it is a precise choice when a reliable coil value is required in a loudspeaker filter network.

Its air-core construction avoids the use of a magnetic core, while the baked winding fixation helps keep the coil mechanically stable. This makes the BL71-0,47 a suitable option among high-quality coils for DIY and replacement crossover work.

The conductor is made from OFC copper SolidCore wire with a 0.40 mm² cross section, corresponding to 21 AWG and a 0.71 mm wire diameter. The coil has a DC resistance of 0.58 Ohm, giving you a clear electrical specification for integration into your crossover design.

With compact Ø30 x H20 mm dimensions and an L3020 coil body type, this Mundorf coil is easy to position inside a crossover layout where space matters. It is well suited for building or servicing passive networks in speakers where consistent component values and solid construction are important.
