High-Temperature Glycol-Based Electrolyte

Our high-temperature glycol-based electrolyte is also used in selected 85 °C types, because it improves energy delivery under load audibly and measurably. It raises the conductivity within the winding, increases ripple current capability and stabilizes the electrical characteristics over temperature and service life. At the same time it stabilizes the winding internally and reduces significant internal relative movement under current load. Beyond that it improves the current flow within the winding at the fine level: impedance and conductivity stay calmer, more even and less modulated even during dynamic load changes.

Laser welded connections

Laser welding the connections of power supply capacitors offers considerable advantages over riveted connections widely used in industry.

Rivetted connections can be very reliable, but remain mechanical press connections whose contact surface and contact pressure can vary minimally due to temperature changes and long-term loads. Laser-welded connections, on the other hand, create a continuous metallurgically connection: The current path becomes more defined, contact resistance decreases, and remains constant even over extended periods of time. This directly improves core electrical data — in particular lower ESR, better current distribution in the coil and higher load capacity for ripple and pulse currents. In addition, it has a macro-microphone stabilizing effect because the internal contact point is mechanically “fixed” and works less under load pulses. As a result, energy is available faster and more evenly at the amplifier stage — without interruptions and without additional modulations.

Tonal effects

• more control during load jumps, less compression at high levels
• More stable bass due to lower supply drops
• quieter overall impression with complex music (less contact modulation)
• more consistent sound over the lifetime due to stable contact points

Maximum Contact between the Coils

The number of contacts or connection lugs between the connection (screw or solder connection) and the coil has a considerable influence on the electrical characteristics of a power supply capacitor. With each additional, sensibly placed contact, ESR and ESL decrease because the current can couple in and out of the coil via several parallel paths. At the same time, eddy current-related losses in the electrode film are reduced because the film is divided into smaller segments in terms of current and no large circulating currents occur. For industrial types, the number of contacts is therefore usually a compromise between electrical performance and economic production. With our top-end capacitors, we are consistently shifting this compromise towards maximum technically feasible contacting.

Tonal effects

• Faster energy flow in case of load jumps, less supply slump
• more control and “punch” in the bass due to lower impedance
• cleaner transients, less reverberation due to lower inductance
• more stable overall impression with high levels and complex music
