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
Non-Magnetic Connections
Non-magnetic connections minimize micro-microphone modulations in the current path. In a power supply capacitor, the current flows not only through the coil, but also through the connecting wires and contact points — and this is exactly where ferromagnetic materials can produce undesired effects. Non-magnetic connection materials avoid magnetization and hysteresis in the conductor and thus reduce current-synchronous, very fine impedance modulations. This is a micro-microphonic measure in the actual power path: The connection is closer to the ideal conductor, without “magnetic interference.” In addition, there is additional electrotechnical benefit because non-magnetic, highly conductive materials often lower and stabilize contact and transition resistances. As a result, energy is available more evenly at the amplifier stage — and the sound remains quieter and more controlled.
Tonal effects
- quieter background and less “grit” with complex music
- more stable transients because the current path is less finely modulated
- clearer contours and cleaner room images at high levels
- more consistent sound quality due to more stable contact and conduction conditions
4Pole technology
4-pole technology separates charging and load current paths — for energy without load-related voltage breaks directly at the amplifier stage.
In power supplies for signal-processing devices such as amplifiers, streamers or mixing consoles, energy storage devices must keep the supply stable enough so that energy is quickly available at all times. In classic power supply capacitors, the charging path (from the rectifier) and the load path (to the amplifier stage) often share the same internal current path — and this is exactly where voltage drops and modulations occur due to ESR and ESL. The Mundorf 4-Pole technology conducts the current differently: input and output are separated so that charge/ripple currents and load pulses influence each other much less. As a result, the common impedance in the critical load path decreases, the supply remains more stable and energy is available where it is needed. The result is less “pumping” of the supply with high dynamics and a significantly higher energy output in real amplifier operation.
Tonal effects
- More stable dynamics during load variations, fewer supply voltage drops
- more controlled bass and cleaner impulses at peak levels
- quieter overall impression with complex music (less supply modulation)
- More precise stage and clearer contours due to a more stable supply at the amplifier stage
MLytic Audiograde
The MLytic Audiograde is designed for small power amplifiers and preamplifiers, where a clean power supply is immediately audible.
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.

Elastic Bonding
Adhesive pads for snap-in capacitors
Self-adhesive mounting pads for snap-in capacitors are inserted under the capacitor between the capacitor base and the circuit board and provide a relieving, vibration-dampening support. They are precisely tailored in diameter to the respective capacitor geometry, do not protrude and facilitate clean, safe installation.
Capacitor mounting clamps
Capacitor mounting clamps hold the capacitor in a form-fitting manner: It is placed in the clamp and securely fixed in the clamp with a screw. The clamp itself is then attached to the circuit board with screws and thus ensures stable, low-vibration assembly, even with larger components.

TubeCap MKP-Film
TubeCap combines the time response – the "speed" – of a film capacitor with high voltage withstand capability – in a compact design.
Aluminum metallization (100% aluminum instead of zinc-aluminum mixture)
Pure aluminum metallization replaces the zinc-aluminum mixture commonly used in industry with a homogeneous metal structure. This reduces interface effects at the grain boundaries , stabilizes the conductivity across the electrode surface and results in a significantly quieter noise spectrum. For example, the basic design of an MCap is audibly different from typical industrial capacitors.
Tonal Effects
- Darker, quieter background — subtle artifacts recede
- Clearer, clearer stage without rough-metallic side effects
- Quiet, well-defined overall sound — a real introduction to audiophile quality
