Electrical Data

Precision Chip Array

PCA Series

Precision thin film technology

Four elements in 1206 footprint

Tight tolerance down to ±0.1%

Low TCR down to ±10ppm/°C

Better TCR tracking and tolerance matching than using discrete parts

Physical Data

Marking

4-digit marking is used on the component. E.g. 1002 = 10KΩ. All relevant information is recorded on the primary package or

reel.

Solvent Resistance

The component is resistant to all normal industrial cleaning solvents suitable for printed circuits.

Construction

A thin-film material is selectively deposited on an 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, and 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.

All parts are Pb-free and comply with EU Directive 2011/65/EU (RoHS2)
