EIA/ECA-576-B:2014

This standard covers thin film precision rectangular leadless discrete fixed resistors with temperature coefficients of ? 50 PPM/?C and tighter and resistance tolerances of 1%, 0.5%, 0.25%, 0.1% and 0.05% for use in surface mounting applications using soldering techniques. Typical Construction Characteristics The termination shall include a leach-resistant barrier layer, made of nickel or an equivalent material. The barrier layer shall be covered with a layer of solderable material.
