Planar terminations
*This dimension determines the number of conductors which may pass under the surface mounted device.
Construction
Thick film resistor material, overglaze and organic protection
are screen printed on a 96% alumina substrate.
Terminations
Planar (or single-sided) termination is gold and suitable for
wire-bonding; wrap around is suitable for soldering.
Adjustment
The components are adjusted to final value using a specially
developed technique, which assures optimum load stability
performance.
Solderability
Wrap-around terminations have an electroplated nickel barrier
and solder coating, this ensures excellent ‘leach’ resistance
properties and solderability. They will withstand immersion in
solder at 260°C for 30 seconds.
