Product details Mundorf BL71-0,82
Mundorf BL71-0,82 0.82 mH MCoil AirCore Baked Varnish Coil 0.79 Ω 2% 21 AWG
The Mundorf BL71-0,82 is part of the MCoil BL AirCore Baked Varnish range, designed as a precision inductor for high-quality passive crossover components. Its 0.82 mH inductance and tight ±2% tolerance make it suitable for carefully specified filter networks where consistent component values matter.
This coil uses an air-core construction, avoiding a magnetic core while providing a defined DC resistance of 0.79 Ω. As one of Mundorf’s baked varnish coils, the winding is fixed for a stable mechanical build.
The conductor is OFC copper SolidCore with a 0.40 mm² cross section, equivalent to AWG 21, with a 0.71 mm wire diameter. This combination gives the BL71-0,82 a clear electrical specification for DIY and replacement crossover projects.
With compact Ø30 x H20 mm dimensions and L3020 coil body type, the BL71-0,82 is easy to position in a crossover layout. It is a practical choice when you need a small air-core inductor with known inductance, resistance and winding construction.
