Visaton Air-Core Inductor 0.68mH, 33g

The Visaton Air-Core Inductor (SP Series) is a high-quality passive electronic component designed for use in a wide range of audio and electronic filter circuits. With a precise inductance value of 0.68mH (680µH) and a low DC resistance of 1.0 Ohm, it is engineered to provide stable and reliable performance in crossover networks, tone control circuits, and other frequency-dependent applications.

Featuring an air-core construction, this inductor eliminates the magnetic saturation and distortion commonly associated with iron or ferrite cores, resulting in cleaner signal transmission and improved audio fidelity. Its robust build ensures consistent inductance across varying current levels, making it a dependable choice for both professional audio equipment and high-fidelity DIY speaker projects.

Key Features & Applications

• Precision Value: A specific inductance of 0.68mH for accurate filter cutoff frequencies.
• Low Resistance: A DC resistance of just 1.0R minimises power loss and heat generation.
• Air-Core Design: Prevents core saturation and non-linear distortion for purer audio signal handling.
• Compact Dimensions: A space-saving form factor (43mm H x 33mm W x 15mm D) allows for flexible integration into various chassis and enclosures.
• Robust Construction: Built for durability and long-term reliability in electronic assemblies.

This inductor is an essential component for constructing passive speaker crossovers, where it works in tandem with capacitors to direct specific frequency ranges to the appropriate drivers (tweeters, midranges, woofers). It is also perfectly suited for use in equalisers, filters for subwoofers, and various other electronic projects requiring precise inductive reactance.
