Metal Film & Foil Resistor
Why are they used?
A Metal Film / Foil resistor is a two-terminal passive electronic component which implements electrical resistance as a circuit element. Metal film / Foil resistors possess good noise characteristics and low non-linearity due to a low voltage coefficient. Also beneficial are the components efficient tolerance, temperature coefficient and stability.
Applications / How do you spot opportunities?
Application, which need resistors for high efficient, Balance operating temperature and greater stability / reliability. (The Selected of different Class Code depend on the Power, Tolerence, Temperature Coefficient).
How to ask for opportunities?
What is the Power dissipation ? What is required precision of the resistance ? What is the temperature coefficient needed?
