Furutech FI-33 NCF(R) High Performance C20 IEC Power Inlet (each)

Furutech FI-33 NCF(R) Power Inlet Delivers High-Performance AC Connectivity

Furutech FI-33 NCF(R) IEC C20 inlet is a high-performance 20A-rated AC power entry solution engineered for uncompromising audio and industrial-grade applications. Designed with Furutech’s exclusive Nano Crystal² Formula (NCF), this premium IEC power inlet redefines what’s possible in AC transmission performance, targeting both electrical efficiency and mechanical damping with precision.

FI-33 NCF(R) Provides Superior Current Handling and Stability

Furutech FI-33 NCF(R) is rated to handle demanding high-current loads, making it ideal for power amplifiers, AC line distributors, and professional audio setups requiring a C20 inlet. The secure terminal system accommodates large-gauge conductors, ensuring solid electrical contact and minimal resistance. Its tight-fit IEC format delivers reliable mechanical connection for uninterrupted power flow, even under dynamic load conditions.

NCF(R) Technology Enhances Electrical and Mechanical Damping

Nano Crystal² Formula (NCF) lies at the core of the FI-33 NCF(R)’s performance advantage. This proprietary compound combines nano-sized crystalline material with ceramic and carbon-based particles, engineered to tackle both static charge and thermal distortion. The formula’s negative ion generation neutralises static buildup, while far-infrared conversion dissipates thermal energy before it introduces electrical noise. The integrated piezoelectric damping further suppresses micro-vibrations and structural resonance, reducing distortion from mechanical interference.

Rhodium-Plated Alpha Copper Conductor Ensures Signal Purity

Furutech’s α (Alpha) pure-copper conductor, treated and finished with rhodium plating, guarantees outstanding conductivity while providing resistance to oxidation and wear. The combination delivers long-term signal stability and improved transient response, making it especially well-suited for high-resolution and wide-dynamic-range audio systems. The plating also contributes to a cleaner, more neutral tonal balance while preserving detail and depth across the frequency spectrum.

Reinforced Housing Supports Anti-Resonant Installation

FI-33 NCF(R)’s chassis uses a high-durability nylon/fibreglass composite, enhanced with Furutech’s NCF-infused resin. This layered construction eliminates resonant behaviour often found in standard plastic housings. The result is a low-noise, mechanically stable component that reinforces both sonic integrity and physical resilience within equipment builds. Whether installed in power conditioners or custom high-end gear, it offers a low-profile yet robust interface between mains power and high-performance circuitry.
