DESCRIPTION ORDERING INFORMATION Table 1 TYPE Ordering code indicating resistor type and packing TOL. (%) ORDERING CODE 2350 502 ..... RESISTANCE VALUE PAPER TAPE ON REEL 5000 units The resistors are constructed on a high grade ceramic body (aluminium oxide). Internal metal electrodes are added at each end and a connection is made between them using a resistive metal glaze; the approximate resistor values are dependent on the composition of the glaze. The resistive layer is covered with a translucent protective coat. Finally, two end electrodes are added, the composition of which has been designed to provide ease of soldering.

Application information TRIMMING INSTRUCTIONS WITH YAG-LASER Typical values for: Cutting speed = 10 to 300 mm/s Laser power = 1 to 6 W Maximum trimming length = 60% of resistor film width Minimum distance between end termination and trimming cut = 0.20 mm. PROTECTION OF LASER CUT With epoxy-phenol lacquers, epoxy resins or silicon alkyd-resins. This is necessary for humidity tests and stability at load. 2003 Jul 11 Rev.3 3 www.yageo.com Phycomp Product specification Trimmable chip resistors size 0603 MECHANICAL DATA RC22TR Outlines Mass per 100 units TYPE RC022TR MASS (g) protective coat resistor layer 0.25 inner electrode Marking T The resistor is not marked.

The testing also covers the requirements specified by EIA and EIAJ. RC22TR testing procedure for electronic components" and under standard atmospheric conditions in accordance with "IEC 60068-1", subclause 5.3. Unless otherwise specified the following values apply: Temperature: 15 C to 35 C Relative humidity: 45% to 75% The tests are carried out in accordance with IEC publication 60068, "Recommended basic climatic and mechanical robustness Table 3 Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar). In Table 3 the tests and requirements are listed with reference to the relevant clauses of "IEC publications 60115-8 and 60068"; a short description of the test procedure is also given. In some instances deviations from the IEC recommendations were necessary for our method of specifying. All soldering tests are performed with mildly activated flux.
