Pasta térmica con óxido metálico, 0.65W/m·K, temperatura entre -40 → +200 °C, 20 ml

Dos tipos de pasta rellenas de óxido metálico, en las que se combinan las propiedades de gran conductividad térmica y alto grado de aislamiento, lo cual asegura una excelente transmisión de calor entre los dispositivos semiconductores y los disipadores de calor. Ambas mejoran el aislamiento eléctrico cuando se emplean de forma normal con las arandelas aislantes y reducen los intervalos de tiempo en los termostatos. Son químicamente inertes, amortiguan los golpes, repelen la humedad y son estables a largo plazo. Un compuesto contiene una base de silicona mientras que el otro se basa en fluidos sintéticos, que reducen cualquier riesgo de contaminación.

This thermal grease adhesive provides an excellent heat transfer between semiconductor devices and heat sinks. It is based on a silicone oil and therefore offers a wide operating temperature range and excellent stability at high temperatures.
Improves electrical isolation when used in the normal way with insulating washers and reduce time lag in thermostats.
This heat sink compound is recommended where the efficient and reliable thermal coupling of electrical and electronic components is required, or between any surface where thermal conductivity or heat dissipation is important.

Wide operating temperature range
Excellent thermal conductivity even at high temperatures
Low in toxicity
White colour enables treated parts to be easily identified
Low evaporation weight loss
Chemically inert (not chemically reactive)
Shock absorbent
Moisture repellent with long-term stability

It should be applied to the base and mounting studs of diodes, transistors, thyristors, heat sinks, silicone rectifiers and semi-conductors, thermostats, power resistors and radiators.

Both 554-311 and 503-357 (Non-Silicon Heat Transfer Compound) are metal filled pastes combining the properties of high thermal conductivity and high insulation resistance. One compound contains a silicone base while the other relies on synthetic fluids, reducing any contamination risk.
