Nov 06, 2009· Mills wire vs. ceramic power resistors. How do you quantify the audible difference of the Mills? Will be employed as tweeter pad, midbass impedance EQ & overall system impedance EQ. Very high quality, high resolution system. Tweeters $90, midbass 2.5 x that. High quality caps, high attention paid to enclosure & driver fasteners.Do Mills resistors REALLY sound different? Techtalk,the answer is yes high watt inductive resistors can roll off the top end. of course most crossovers dont use 50 watt resistors or 5 10 watt resistors. I agree that the mills and eagle resistors are better made. here is a link to a 2 ohm 50 watt resistor that will roll your tweeter off.Mills Hifi Collective,Mills Mills Series Non-Inductive wirewound power resistors are very popular in audio, infinitely better than the ceramic "grey" type. An Aryton-Perry design with tinned copper leads, silver plated end caps. The core material is an alumina ceramic, providing significantly broader heat dissipation compared to that of normal steatite ceramic core.
Jun 27, 2018· It’s made from three different elements which are plastic, ceramic, and glass. These materials give wire-wound resistors a high resistivity. wire-wound resistor. A high wattage and high resistivity resistor hasn’t prevented wire-wound resistors from becoming one of, if not the most manufactured resistor to this day.Mills wirewound resistors.any "foo-ier" alternatives,Nov 12, 2009· ok..so I got some more info from Duke(the speaker builder) The interchangeable tweeter-level-modifying resistors that go in that external cup were Mills 1% 12-watt non-inductive wirewounds, and the values were 30 ohms, 47 ohms, and 82 ohms.Resistor Types Does It Matter? Aiken Amps,One more consideration for resistors: it is sometimes overlooked that resistors have a max voltage rating. The 1/2 watters and some 1 watters usually are only rated for 250-350V. Be sure to get a resistor rated for the appropriate voltage in the amplifier. I use only 1W, 500V min (continuous, 1000V surge) or 2W, 750V rated resistors.

Wire wound resistors exist for very high power applications. The range varies from 0.5 watts till more than 1000 watts. Power wirewound resistors can be divided in types according to the coating type. Silicone resins are used for the lowest dissipation levels.
Power wire wound resistors are available in low, medium and high power types as : 3, 5, 10 Watts (low); 10 to 60 W (medium), 60-1000 watts (high power). Precision wire wound resistors are wound on ceramic Power resistor Resistor applications Resistor Guide,A power resistor is a resistor designed and manufactured to dissipate large amounts of power in a compact physical package. Types and construction Wirewound resistors. Wire wound resistors are made by winding a metal wire around a solid form, often made of ceramicResistors: Types And Applications Nuts & Volts Magazine,Ceramic and Metal Oxide If you need a high-power non-inductive resistor, you can use cermet (ceramic-metal mix) or metal oxide resistors. These are constructed much like a carbon comp resistor, substituting the cermet or metal oxide for the carbon composition material. Adjustable Resistors There are many different types of adjustable resistors.
Ceramic Wirewound resistors are build up from a ceramic core where a resistor wire in wound on. The are offered in various diameters ranging from 10 till 55mm and lengths from 44 till 590mm. The Wirewound resistor Resistor materials Resistor Guide,Power wirewound. Wire wound resistors exist for very high power applications. The range varies from 0.5 watts till more than 1000 watts. Power wirewound resistors can be divided in types according to Wirewound Resistors, Non-Magnetic, Non-Inductive, Axial Lead,(1) Vishay Mills MRA models have two power ratings depending on the operation temperature and stability requirements. (2) Other tolerances may be available, contact factory STANDARD ELECTRICAL SPECIFICATIONS GLOBAL MODEL HISTORICAL MODEL POWER RATING (1) P25 °C W CHARACTERISTIC U + 250 °C POWER
Power wire wound resistors are available in low, medium and high power types as : 3, 5, 10 Watts (low); 10 to 60 W (medium), 60-1000 watts (high power). Precision wire wound resistors are wound on ceramic tubes and sometimes epoxy moulded tubes are used. The winding is so done so as to minimize inductive and capacitive effects at highResistors: Types And Applications Nuts & Volts Magazine,Ceramic and Metal Oxide If you need a high-power non-inductive resistor, you can use cermet (ceramic-metal mix) or metal oxide resistors. These are constructed much like a carbon comp resistor, substituting the cermet or metal oxide for the carbon composition material. Adjustable Resistors There are many different types of adjustable resistors.Resistor Wikipedia,Wire leads in low power wirewound resistors are usually between 0.6 and 0.8 mm in diameter and tinned for ease of soldering. For higher power wirewound resistors, either a ceramic outer case or an aluminum outer case on top of an insulating layer is used if the outer case is ceramic, such resistors are sometimes described as "cement
"Cement resistor" only describes the appearance of common power resistors like that shown above. It is a nickname for the heat resistant ceramic case in which a coil of resistance wire is potted. They are most often, wire-wound resistors. However even this description is out of date.Choosing the Right Resistor for Your Amplifier Project,Dec 06, 2010· Another area of the amp circuit that should not contain carbon-comp. resistors is the power supply. Since most carbon-comp. resistors new and old are not UL94-VO protected, which is a flameproof coating, they should stay away from the B line. One more thing to consider is the power What is the BEST resistor for audio use Audiogon,Nov 24, 2001· The Vishay "metal foil" is still the most transparent for low-level applications, but they simply aren't feasible in high voltage/power applications. The only problem with Holcos are that they don't like high voltages (>150 V) regardless of their specs, and
Nov 16, 2007· I've been assured that, with 2.7ohm/2W resistors, I shouldn't be in any danger here, but, were I to change these out for Riken carbon film resistors, say, or for Mills wire-wound resistors (both reputed to sound "the best"), I could be placing the amp at some unknown risk.50 Ohms 50 W Resistors Mouser,50 Ohms 50 W Resistors are available at Mouser Electronics.

Power supplies use precision resistors at or near rated power more often than many other applications. There are still many occurrences of precision resistors used in voltage division, or to set gain or other types of feedback where the need for reliable, cost-effective precision resistors are critical. One example would be automotive powerWhy would a circuit designer use parallel resistors,Read work by Walt Jung on sizing resistors, to reduce thermal distortion that degrades Power Audio Amplifiers. The thermal time constant of 1 cubic centimeter of silicon (clay? ceramic base of resistors?) is 114 seconds. The thermal time constant of 1 cubic millimeter (about the size of a SMT resistor) is 100X faster at 1.14 seconds.,
