Wrap-around terminations
(3 faces)
Construction
Thick film resistor material, overglaze and organic protection
are screen printed on a 96% alumina substrate. Wrap-around
terminations have an electroplated nickel barrier and solder
coating, this ensures excellent ‘leach’ resistance properties
and solderability.
Note that anti-sulphur version parts below 100R are
produced in flip-chip format with the resistor element on
the underside.
Marking
Components are not marked. Reels are marked with type,
value, tolerance, date code and quantity.
Solvent Resistance
The body protection is resistant to all normal industrial
cleaning solvents suitable for printed circuits.
