Resistors
CR Series
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.
Performance Data
Note: An 0.01 ohm addition to be added to the performance of all resistors <10 ohms

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.
