Surface Mounted Resistors - CR Series

The chips themselves can work at a maximum temperature of 155 °C (see performance claims above). For soldered chips, the joint temperature should not go beyond 110 °C. This condition is matched when the stated power levels at 70 °C are used.

The ‘F’ terminations offer good leach properties and guarantee reliable contact. As a result of the strong construction, the resistor chip can be immersed in the solder bath for 30 seconds at 260 °C. This enables the resistor to be fixed on one side of a printed circuit board and other wire-leaded components on the other side.


Wrap-around Termination

The chip resistors are provided taped and reeled on standard 8 mm tape to IEC 286-3.

Planar Terminations

The resistor chips are delivered in waffle packs.


This chip resistor is perfectly suited for handling by automatic techniques because of its rectangular shape and the small dimensional tolerances. Electrical connection to a ceramic substrate or to a printed circuit board can be done by wire bonding (for example, suffix ‘G’ in CR0805G) or by reflow soldering of wrap-around terminations (for example, suffix ‘F’ in CR0805F).


The thick film resistor material, overglaze, and organic protection are screen printed on a 96% alumina substrate.


Planar (or single-sided) termination is gold and ideal for wire-bonding; wrap-around is ideal for soldering.


The wrap-around terminations have an electroplated nickel barrier and solder coating, which ensures exceptional ‘leach’ resistance properties and solderability. They will endure immersion in solder at 260 °C for 30 seconds.
