Furutech FI-52 (R) C19 Delivers Pure Transmission for High-Current Audio Systems
Furutech FI-52 (R) C19 IEC power connector is a high-performance 20A-rated component engineered for uncompromising audiophile-grade AC power delivery. This reference-grade connector from the Furutech Piezo Ceramic and Carbon Series integrates advanced vibration-damping materials and precision-machined construction to ensure exceptional signal integrity for high-current power cables.
FI-52 (R) C19 Combines Piezo Ceramic Technology with Carbon Fibre Housing
Furutech FI-52 (R) C19 is designed with a multi-material architecture that maximises electrical damping and vibration control. Its unique outer shell combines nonmagnetic stainless steel with carbon fibre layers, forming a rigid, acoustically inert casing. Inside, a custom-engineered acetal copolymer layer provides further damping and insulation, eliminating micro-vibrations that degrade power transmission.
Furutech incorporates nano-sized ceramic particles with powdered carbon within the nylon/fibreglass body of the connector. This composite formulation harnesses piezoelectric properties, actively converting mechanical pressure into electric energy, then dissipating it as harmless heat through the carbon matrix. This proprietary material approach reduces mechanical and electrical resonance across the connector body, preserving the tonal balance and frequency extension in premium audio systems.
FI-52 (R) C19 Uses Alpha Pure Copper Rhodium-Plated Conductors for Maximum Conductivity
Furutech’s α (Alpha) Pure Copper conductors, precision-plated with rhodium, form the electrical heart of the FI-52 (R) C19 Piezo Ceramic Series connector. These high-purity conductors deliver outstanding conductivity and corrosion resistance, supporting current loads of 20A at 125V or 16A at 250V AC. The rhodium plating ensures long-term performance consistency under demanding use.
An internal earth (ground) jumper system enhances grounding stability, further minimising noise ingress and potential ground loop interference. The result is a cleaner power supply path for reference-grade equipment like monoblock amplifiers, power conditioners, or flagship DACs.
FI-52 (R) C19 Features Precision Clamping and Broad Cable Compatibility
Furutech FI-52 (R) C19 Carbon Series power connector supports power cable diameters from 6mm to 20mm, offering wide compatibility with high-end power cords. A robust metal cable clamp ensures solid mechanical contact while eliminating strain that could otherwise introduce distortion. The secure grip also enhances long-term reliability by reducing micro-movement at the connection point.
This connector’s geometry follows the 2-pole + earth IEC C19 standard, making it an ideal choice for audio components requiring higher current handling than standard C13 connectors allow. Its 77.2mm overall length and 39.0mm diameter are well-suited to professional installations where space efficiency and performance coexist.
FI-52 (R) C19 Enables Signal Purity Through Mechanical-Electrical Energy Interconversion
Furutech’s Piezo Ceramic innovation, implemented in the FI-52 (R) C19 Carbon Series, introduces a new class of power connector that interconverts mechanical, thermal, and electrical energy to actively suppress resonance. The embedded ferroelectric ceramic micro-particles respond to internal mechanical stress by generating an electrical charge, which, when combined with the thermal-conductive carbon particles, transforms unwanted energy into heat that dissipates away from the connector’s body.
This process not only reduces high-frequency noise and electromagnetic interference but also preserves micro-dynamic detail and transient accuracy in high-resolution playback systems. The result is a power connector that operates as a passive filter—eliminating colouration and ensuring a smoother, more extended frequency response.
Furutech FI-52 (R) C19 IEC connector represents the culmination of advanced materials science, exacting Japanese manufacturing standards, and audiophile listening tests. It stands as an elite solution for those demanding the purest AC power delivery in their reference audio setups.
