Mundorf BL71-1,5 1.5 mH MCoil AirCore Baked Varnish Coil 1.11 Ohm

The Mundorf BL71-1,5 belongs to the MCoil BL AirCore Baked Varnish series and is designed for accurate use in passive crossover components. With an inductance of 1.5 mH and a tight ±2% tolerance, it is well suited for builders who need predictable values in speaker filter networks.

This air-core coil uses an OFC copper SolidCore conductor with a 0.40 mm² cross section, equivalent to AWG 21, and a wire diameter of 0.71 mm. The 1.11 Ohm DC resistance makes it easy to factor the coil into crossover calculations and component matching.

The baked winding fixation helps maintain the coil’s mechanical stability. This construction is useful when selecting reliable coils for DIY loudspeaker projects, repairs, or custom crossover assemblies where consistent component values matter.

With compact dimensions of Ø40 x H20 mm and coil body type L4020, the BL71-1,5 is practical to place inside many speakers and crossover layouts. It provides a straightforward, high-quality inductor option from Mundorf’s established MCoil range.
