Mresist Ultra 0,47 Ohm 3-30W

The Mundorf MResist Ultra resistors are based on the well-known good tonal properties of copper-manganin foil which provides an order of magnitude lower inductance. Copper is significantly softer than the metal-oxide used for MOX resistors. The natural resonances of the copper-manganin foil are therefore significantly less pronounced, which means that distortions caused by crystallurgy and electroacoustics are significantly reduced here. That is why resistors of this design have secured a top position among audio components in recent years: They lack many of the distortions inherent in other resistor designs.
Rated 3W without heat sink or 30W with optional heatsink added.
Size (LxWxH): 15,5 x 21,1 x 4,6 mm.
