Compound as a powder used in the manufacture of electrical resistors to isolate the Resistive Spiral of the Metal sheath. Once compacted by rolling or compression is achieved good Thermal Conductivity while ensuring the Electrical insulation correcto El porcentaje y tamaño del grano influye en la vida de las resistencias.

Onda media

Is a physical parameter that indicates the size of a wave and is usually denoted by the Greek letter lambda ( the ). In the international system, Unit of measure Longitude de onda is the subway, al igual que cualquier otra distancia.
Since the orders of magnitude of this parameter, for convenience is often used as the millimeter submultiples (mm for all lengths), micrometer (µm) and naked (nm).
In heating, depending on the material, thickness, speeds Process, temperature, etc are used issuers Infrared with different wavelengths. The criterion for the type of issuer may have slight variations depending on the manufacturer. In Electricfor to differentiate issuers Infrared we have established the following criterion:
• Wave cut: Longitude de onda between 0,8 and 1,8 µm
• Onda media: Longitude de onda between 1,8 and 3,5 µm
• Onda larga: Longitude de onda between 3,5 and 8 µm

Ohm (W)

alpha — Fri, 16 May 2014 15:43:17 +0000

Unidad de resistencia eléctrica en el Sistema Internacional de Unidades. Se representa con la letra griega W (Omega). Según la Ley de Ohm, un ohmio es la resistencia eléctrica que presenta un conductor al paso de una corriente eléctrica de un Amperio, cuando la Potential difference entre sus extremos es de un voltio.
r = V / I
Donde r = Ohms; I = Amperio ;V = Voltios
