Key Features
■Thin film precision resistors
with TC's of 25 and 50ppm
and tolerances to 0.1%.
Applications in measurement,
telemetry and for sensing
circuits.
■Case sizes 0402, 0603, 0805,
1206, 2010 and 2512
■CPF chip resistors are
suitable for all applications
where close accuracy and
stability are essential
Type CPF Series
Precision metal terminations are screen
printed onto a ceramic base and fired.
The resistive element is sputtered and
fired and the passivation layer added.
The pre-scribed tile is broken into
strips, the end plating is fired on and
the strips broken into individual
components. Final termination is made
by electroplating.

Performance Characteristics
The evaluation of the performance characteristics is carried out with reference to IECQ
specifications QC 400 000 and QC 400 100.
Storage
Unopened reels should be stored within a temperature range of +5 °C to +25 °C, separated from any dust, chemicals and
solvent based materials. Non-adherence to this procedure could affect the solderability of this product.
