Mundorf BL71-0,33 0.33 mH MCoil AirCore Baked Varnish Coil
The Mundorf BL71-0,33 is designed for precise use in passive loudspeaker networks and other crossover components. With an inductance of 0.33 mH and a tight ±2% tolerance, it is well suited for builders who need predictable values when tuning or replacing crossover parts.
As part of Mundorf’s MCoil BL AirCore Baked Varnish range, this component uses an air-core construction and OFC copper SolidCore conductor. The baked winding fixation helps keep the winding stable, making it a dependable choice among high-quality coils for audio crossover assemblies.
The BL71-0,33 has a DC resistance of 0.47 Ohm and uses 0.40 mm² wire, specified as AWG 21 with a 0.71 mm conductor diameter. These electrical characteristics make it suitable for compact crossover designs where the specified inductance, resistance, and wire gauge are important to the circuit.
With dimensions of Ø30 x H20 mm and Mundorf coil body type L3020, this coil is easy to integrate into speaker projects, repairs, and custom audio components. Its compact size makes it practical for space-conscious crossover layouts while retaining the defined parameters needed for accurate filter design.
