Adjustment

Solderability

The components are adjusted to final value using a specially

developed technique, which assures optimum load stability

performance.

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.

Application Notes

Operating Temperature Range

Packaging

The chips can operate at a maximum temperature of 155°C

(see Performance Data). For soldered chips, the joint

temperature should not exceed 110°C. This condition is met

when the stated power levels at 70°C are used.

Resistor chips are supplied taped and reeled on standard 8mm

tape to IEC 286-3.

Quantity per reel 3000 max.

Planar Terminations

Resistor chips are supplied in waffle packs.

Mounting

This chip resistor is ideally suited for handling by automatic

methods due to its rectangular shape and the small

dimensional tolerances. Electrical connection to a ceramic

substrate or to a printed circuit board can be made by wire

bonding (eg suffix ‘G’ in PCR0805G) or by reflow soldering of

wrap-around terminations (eg suffix ‘F’ in PCR0805F). The ‘F’

terminations provide good leach properties and ensure

reliable contact. Due to the robust construction the resistor

chip can be immersed in the solder bath for 30 seconds at

260°C. This enables the resistor to be mounted on one side

of a printed circuit and other wire-leaded components on the

other side.
