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.
Marking
Components are not marked. Reels are marked with type,
value, tolerance, date code and quantity.
Solvent Resitance
The body protection is resistant to all normal industrial
cleaning solvents suitable for printed circuits.
General Note
Welwyn Components reserves the right to make changes in product specification without notice or liability.
All information is subject to Welwyn’s own data and is considered accurate at time of going to print.
