LH45
Ferrite roll-core coil based on the high-performance ferrite HP3616 for compact and particularly precise small-signal applications. The hepta strand, consisting of seven individual baked varnish wires, ensures a mechanically stable construction.
Baked Varnish Wire/ Resin Soaking
Baked varnish wire is enamel-insulated wire with an additional, activatable hot-melt outer layer, which has an adhesive effect when heated. The windings are thus fixed together.
Impact in practice
- The coil becomes mechanically stable and „works“ significantly less
- Micro-movements between windings are reduced
- In particular, this reduces macro-microphonic effects (the windings „work“ less) and increases “silence” during operation
Resin soaking as an alternative to baked varnish wire
If no baked lacquer wire is used, resin soaking carried out under vacuum can take over the mechanical fixing. The resin penetrates into the wrap, reduces cavities and degrees of freedom of movement and transforms the wrap into a stable compound. The result: significantly less macro microphones and an overall quieter, more precise operation of the coil.
Aronit Core
Aronit is an iron powder composite core that processes high currents very reliably. Due to the material and construction, behavior remains benign under load, and saturation sets in late and softly. At the same time, eddy current losses are significantly reduced because the iron particles are electrically insulated from one another by the plastic bond.
The result is a robust, level-resistant coil with a stable filter effect. Ideal for bass and fundamental frequency branches when high currents need to be processed safely.
Stranded wire as hepta strand
The division into several individual wires can promote power distribution in the conductor and thus reduce additional losses in certain applications.
Strengths
- Can support clean, controlled power distribution for appropriate tasks
- Hot-melt wire provides excellent mechanical stabilization of the winding on a stranded wire coil
- Interesting for correction elements (equalizer coils) and selected midrange tasks
OFC Copper
- Purity: at least 99.995% Cu, often 99.999% (4N) or higher
- Feature: almost oxygen-free (typically <10 ppm)
- Result: more stable grain boundaries, less oxide formation, more uniform electron flow
