Mundorf BL71-0,39 0,39 mH MCoil AirCore Baked Varnish Coil 0,52 Ohm 2% 21 AWG
The Mundorf BL71-0,39 is part of the MCoil BL AirCore Baked Varnish series, designed for reliable use among high-quality coils in audio crossover designs. Its 0,39 mH inductance and ±2% tolerance make it a precise component choice where predictable electrical values are required.
This coil uses an air-core construction, avoiding a magnetic core material in the signal path. The winding is baked for mechanical fixation, helping the coil maintain its structure during installation and use in crossover components assemblies.
The conductor is made from OFC copper SolidCore wire with a 0,40 mm² cross section, corresponding to AWG 21 and a 0,71 mm wire diameter. With a DC resistance of 0,52 Ohm, this model provides the specified electrical behavior in a compact format.
Measuring Ø30 x H20 mm, the BL71-0,39 fits neatly into space-conscious crossover layouts. Its coil body type is L3020, matching the compact dimensions and making it practical for organized internal mounting in speaker projects.
