H100
Ferrite drum core coil with an H-core configuration based on the high-performance ferrite HP3616 for compact and precise applications. The closed magnetic circuit enables particularly low RDC values combined with high efficiency in a compact design.
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
Round Wire
Round wire coils are the tried and tested standard design: A solid conductor is formed into a winding and provides an easily calculable inductance. In terms of sound, DC resistance (RDC) is decisive here because it directly influences efficiency and control — especially in the bass range.
Ferrite HP3616
HP3616 is our precision material for low-signal applications: fast, clean and very compact. Particularly in correction links, equalizers and selected midrange tasks, he shows his strength in clarity and definition.
The design is decisive for high currents in the bass, as the magnetization reserves are limited.
