Dayton Audio LW18-33 | 0.33 mH | 0.28 Ω | 5% | 18 AWG

The Dayton Audio LW18-33 is a precision-engineered air core inductor designed to elevate the performance of your speaker crossover networks. This 0.33 mH coil delivers accurate filtering, ensuring that each driver receives only the frequencies it was intended to handle, resulting in a cleaner, more natural soundstage. Ideal for audiophiles and DIY enthusiasts alike, it is perfectly suited for use in two-way or three-way speaker systems, as well as for custom crossover upgrades in existing designs.

Constructed with 18 AWG wire, this inductor offers a low DC resistance of just 0.28 Ω, minimising signal loss and preserving the integrity of your audio path. The ±5% tolerance guarantees consistent performance across multiple units, making it reliable for both prototyping and production. Its perfect layer winding technique reduces parasitic capacitance and distortion, while the air core design eliminates core saturation, ensuring linear behaviour even at higher power levels. Measuring 39 x 17 mm, this compact coil integrates easily into most crossover boards. With a power handling of 3 watts RMS, the LW18-33 is a robust choice for high-fidelity audio projects, delivering transparent and accurate sound reproduction.
