Furutech’s Pure Transmission FI-50 NCF Piezo Ceramic series connector bodies and housings feature several breakthrough construction techniques.


NCF Connector body

Incorporates an “active” damping material: Nano Crystal Formula - Nano Crystalline, Ceramic and Carbon Powder. NCF is comprised of a special crystalline material that has two “active” properties. First, it generates negative ions that eliminate static. Second, it converts thermal energy into far-infrared. Furutech then combines this remarkable crystalline material with nano-sized ceramic particles and carbon powder for their additional “Piezo Effect” damping properties. The resulting Nano Crystal Formula is the ultimate electrical and mechanical damping material – only found in Furutech products!


Nano Crystal Formula:

Eliminates static

Converts thermal energy

Dampens vibration

Stainless Steel and Silver Plated Carbon Fiber Shell

Incorporates a special damping and insulating Acetal copolymer. Furutech settled on multilayer nonmagnetic stainless steel and silver plated carbon fiber for the outer housing after extensive listening sessions with Japanese industry figures and audiophiles.


Floating Magnetic Field Effects - The Furutech Earth/Ground Jumper System

How far will Furutech’s engineers go in their attempts to reach Pure Transmission reference quality? Their concentrated examination of each and every element of signal transfer has resulted in another breakthrough technology, the Furutech Earth/Ground Jumper System. It eliminates EMI (Electromagnetic Interference) induced in metal parts like connector housing screws. Current flowing through the power connector creates a magnetic field, just as an insulated conductor creates both electromagnetic and electrostatic fields. Furutech engineers found this magnetic field induces current flow (and a small magnetic field) in the screws holding the connector together! These magnetic fields interfere with the larger magnetic field around the conductor and connector. Furutech’s total attention to detail and elegant engineering neatly solves the problem. The Earth/Ground Jumper System connects the securing screws to a ground terminal within the plug completely eliminating the field disturbances they cause. The stray fields are grounded by a series of interlocking parts within the connector that attach to the ground conductor. The Jumper System is available in Furutech NEMA Power and IEC Connectors.   The Earth/Ground Jumper System Carries US Patent No. 6,669,491

The previous FI-50 power connectors were great. The addition of the Nano Crystal Formula has taken the connectors to the next level of performance. These are our new reference!
