This Jantzen Audio Litz Wire Wax air-core inductor has an inductance of 0.47 mH, a DCR of 0.23 ohm and a 7x0.5 mm Litz-wire conductor. It combines a coreless design with multi-strand Litz wire and wax impregnation that stabilises the winding.

The model is intended for high-quality midrange and tweeter filters, correction networks and designs where reduced skin effect and lower winding vibration are important.

Description

The Litz-wire conductor consists of 7 individually insulated strands, each with a diameter of 0.5 mm. This construction distributes current more evenly than a single conductor of comparable cross-section.

After winding, the inductor is impregnated with paraffin wax. The hardened winding is less susceptible to movement and vibration, while the air-core construction eliminates magnetic saturation and hysteresis.

The combination of Litz wire and wax impregnation is intended primarily for high-quality hi-fi crossovers where mechanical stability, low conductor loss at higher frequencies and premium construction are important.

Application

high-quality midrange and tweeter filters,
RLC networks, resonance traps and impedance correction,
crossover upgrades requiring Litz wire,
advanced hi-fi and DIY loudspeaker projects,
filters where reduced skin-effect influence is important.

Effect of construction on sound

The multi-strand conductor reduces the influence of skin effect, while wax impregnation stabilises the winding. In a properly designed filter this can support clean, precise and effortless reproduction of mid and high frequencies with good detail retrieval. The final result still depends on inductance, DCR and the other crossover components.

Why choose this model?

The 0.47 mH inductance allows the component to be used in filters requiring this specific value. Its winding resistance of 0.23 ohm should be included in the crossover design because it affects signal level, damping and the electrical response of the connected loudspeaker.

The 7x0.5 mm Litz-wire conductor combines several individually insulated strands for improved current distribution. This model is therefore particularly suitable for midrange and selected woofer filters where low high-frequency conductor losses are important. Its low series resistance helps preserve loudspeaker sensitivity and control in the filter section.

Key features

Litz-wire conductor made from 7 strands of 0.5 mm each,
individual insulation on every strand,
air-core construction with no core saturation,
paraffin-wax impregnation,
reduced skin-effect influence and winding vibration,
inductance tolerance of ±3%.

Installation

Secure the inductor with a wide cable tie or a holder with a soft protective pad. The mounting should not excessively compress the wax-impregnated winding or stress the leads.

Do not pass a steel screw through the centre of the coil. When several inductors are installed on one board, position their axes at 90 degrees and maintain as much spacing as practical.

Avoid prolonged heating of the leads during soldering. For matched crossover pairs, check the actual inductance and DCR before installation.

Product safety information:

Jantzen Audio components are intended for use in passive loudspeaker crossovers, loudspeaker construction and DIY audio projects. Installation should be carried out by an adult with suitable technical knowledge and experience in working with electronic components.

These products are not toys. Keep all components, wires, small parts and packaging materials away from children and animals.

Before installation, disconnect the audio equipment from the mains supply and all other power sources. Make sure that the amplifier and connected devices cannot be switched on accidentally while work is being carried out.

Always use the product within the voltage, current, power and temperature limits specified by the manufacturer. Check the product markings, technical data and available datasheets before installation. Components with an incorrect rating may overheat, become damaged or cause damage to other parts of the audio system.

Inductors, resistors and other crossover components may become hot during operation. Provide adequate ventilation and maintain sufficient distance from materials that may be damaged by heat. Components should be mounted securely so that their weight and vibration do not place stress on the leads or solder joints.

Capacitors may retain an electrical charge after the equipment has been switched off. Before touching or replacing a capacitor, discharge it safely using an appropriate resistor and measuring equipment. Do not discharge a capacitor by directly short-circuiting its terminals.

When soldering, use suitable tools, eye protection and adequate ventilation. Avoid excessive heating of component leads and insulation. Cut leads and metal terminals may have sharp edges and should be handled carefully.

Do not install components that are visibly damaged, deformed, swollen, cracked, corroded or affected by moisture. Stop using the equipment immediately if you notice excessive heat, smoke, an unusual smell, discolouration or other signs of damage.

Unless otherwise stated in the product documentation, components should be used only in dry indoor environments. Protect them from water, condensation, excessive humidity, dust, chemicals, direct sunlight and temperatures outside the permitted operating range.

Air-core inductors should not be mounted with a steel screw passing through the centre of the winding, as ferromagnetic material may alter their electrical properties. When several inductors are installed close together, they should be spaced apart and positioned with their axes at different angles to reduce magnetic interaction.

Use cables with an appropriate conductor size and insulation. All electrical connections must be properly soldered, insulated and protected against accidental short circuits. Make sure that components cannot move inside the loudspeaker enclosure during transport or operation.

Do not modify, unwind, drill, crush, cut open or otherwise alter the components. Any modification may change their electrical parameters and compromise safe operation.

Dispose of damaged or unused components and packaging in accordance with local regulations. Do not burn electronic components, insulation materials or packaging.

Product-specific technical data, installation instructions and warnings take precedence over this general safety information. If there is any uncertainty about product selection or installation, consult a qualified loudspeaker technician or electronics specialist.
