Construction

A thin-film material is selectively deposited on a 96% alumina substrate together with metallic contacts at each end of the resistor.

The unadjusted resistors are heat treated to give the required TCR and stability, then a precisely controlled laser trim process adjusts

the resistance value. Epoxy protection is applied and wrap-around terminations are added and plated with Nickel then Tin. Each

resistor is measured immediately before packing into tape.

Terminations

The chips are supplied with 100% Sn matte plated wrap-around terminations suitable for soldering.

* Standard values E24 or E96. Other values may be available by request.
