Supertech 4TTN T Network Capacitors

Supertech 4TTN T Network Capacitors

The Guided Current 4TTN (T-Network) capacitor originally evolved because DNM Design required reservoirs that behaved only as capacitors, without unwanted effects such as stray resistance, inductance and eddy current generation caused by the presence of two vast conducting surfaces in the circuit.

DNM Design, in association with SuperTech, developed the Guided Current 4TTN (T-Network) capacitor to minimise these unwanted effects. Instead of the single positive and negative terminals found on two terminal capacitors, the Guided Current 4TTN (T-Network) has 2 inputs and 2 outputs.

These extra terminals are connected in a T pattern at the centre and ends of each capacitor plate, guiding the plate current along a controlled path. The Guided Current 4TTN (T-Network) design reduces the effect of unwanted resistance and inductance and the technology is combined with slit foil plates to eliminate eddy currents.

These capacitors are an order of magnitude better than normal 2 terminal ones and they transform the performance of linear and switching audio amplifiers.
In tests under load, the 4TTN capacitor's ability to attenuate is 11dB better than a two terminal capacitor and this extra performance is maintained up to extremely high frequencies

Subjectively, the performance of the Guided Current 4TTN (T-Network) is absolutely unparalleled - it transforms the sound of even the best amplifiers.

Objectively, Guided Current 4TTN (T-Network) capacitors improve the measured high-frequency filtering by reducing the source impedance of the power supply. The high frequency advantage offered by the Guided Current 4TTN (T-Network) has additional benefits for manufacturers trying to comply with EMC regulations.
