AudioCap Copper

AudioCap Cu TFTCU PTFE and Copper Foil

AudioCap Copper

AudioCap Copper explores true copper-foil capacitor construction across distinctly different dielectric and structural approaches. From polypropylene to PTFE, each series uses solid copper foil as the electrode material, creating a clear distinction from conventional metallized capacitor designs.

PPTCu combines polypropylene with solid copper foil, while TFTCu pairs copper foil with PTFE, copper-sprayed terminations and 99.99% OFHC copper leads. At the top of the range, TFTCuX adds Reliable’s proprietary AudioCapX multi-section architecture, dividing the capacitor into internally connected sections to further reduce effective series resistance and inductance.

The result is a progression of genuinely different copper-foil designs – from an unusually accessible entry into true copper-foil construction to combinations of materials and architecture found nowhere else in the Reliable range.

PPTCu

Polypropylene & Copper Foil

PPPTCu takes a deliberately straightforward approach: a polypropylene dielectric combined with solid copper foil rather than a metallized electrode. This true film-and-foil construction gives copper a direct role in the signal path and clearly separates PPTCu from conventional metallized polypropylene capacitors.

Within the AudioCap Copper range, PPTCu represents the most direct expression of the copper-foil concept – without the additional complexity of PTFE or the AudioCapX multi-section architecture. It provides an unusually accessible entry into true copper-foil construction while retaining the familiar characteristics of a polypropylene dielectric.

TFTCu

PTFE & Copper Foil

TFTCu combines a PTFE dielectric with solid copper foil in a construction based on very low-loss materials. The capacitor ends are sprayed with copper rather than conventional tin alloys, while 99.99% OFHC copper leads continue the copper-based construction beyond the winding itself.

Within the AudioCap Copper range, TFTCu represents the step from polypropylene to PTFE while retaining true copper-foil electrodes. It is a deliberately uncompromising material combination – technically distinct from PPTCu and without the additional multi-section architecture reserved for TFTCuX.

TFTCuX

PTFE & Copper Foil · Multi-Section

TFTCuX combines a PTFE dielectric and solid copper-foil electrodes with Reliable’s proprietary AudioCapX multi-section architecture. Multiple capacitor sections are internally connected in parallel, reducing effective series resistance and inductance compared with a conventional single-section construction.

Within the AudioCap Copper range, TFTCuX represents the combination of the PTFE and copper-foil construction used in TFTCu with the additional multi-section architecture of AudioCapX. It therefore brings together the material approach of the copper-foil series with the structural concept that defines AudioCapX.
