Mundorf BL71-0,27 0.27 mH MCoil AirCore Baked Varnish Coil 0.42 Ohm 2% 21 AWG

The Mundorf BL71-0,27 is part of the MCoil BL AirCore Baked Varnish series, designed for use in passive speaker crossover networks and other precision crossover components. Its 0.27 mH inductance and ±2% tolerance make it suitable for designs where predictable component values are important.

As an air-core coil, the BL71-0,27 uses an OFC copper SolidCore conductor rather than a magnetic core. This construction supports clean signal handling while the baked winding fixation helps keep the coil mechanically stable in the crossover layout.

The coil has a DC resistance of 0.42 Ohm and uses 0.40 mm² wire, equivalent to AWG 21 with a 0.71 mm conductor diameter. With compact Ø30 x H20 mm dimensions, it is easy to integrate into speaker projects where space for coils is limited.

Choose the BL71-0,27 when you need a compact Mundorf air-core baked varnish inductor with tightly specified electrical values for DIY or replacement crossover work.
