Construction
Conductors, resistive element and protection are applied to a 96% alumina substrate. The design and laser
adjustment of the resistive element optimises the fusing performance of the resistor.
Terminations
The chips are supplied with wrap-around terminations suitable for soldering.
Solderability
The terminations have an electroplated nickel barrier and 100% matt tin finish. This ensures excellent ‘leach’
resistance properties and solderability.
Marking
The body protection is resistant to all normal cleaning solvents suitable for printed circuits. All resistors are
individually marked with 3 digits. The first two digits are the significant figures and the third defines the number of
added zeros.
