DATA SHEET THIN-FILM CHIP RESISTORS TFx20 series, 1% TC50 10 TO 1 M Product Specification - Jul 10, 2003 V.2 sizes 1210, 1206, 0805, 0603 and 0402 Phycomp Product specification Thin-film chip resistors sizes 1210, 1206, 0805, 0603 and 0402 TFx20 series, 1% TC50 10 to 1 M FEATURES DESCRIPTION * High precision The resistors are constructed on a high grade ceramic body (aluminium oxide). Internal metal electrodes are added at each end and connected by a resistive paste which is applied to the top surface of the substrate. The composition of the paste is adjusted to give the approximate resistance required and the value is trimmed to within tolerance by laser cutting of this resistive layer. * High long-tem stability * Low temperature coefficient. APPLICATIONS * Converters * Printer equipment * Motherboards The resistive layer is covered with a protective coating and printed with the resistance value. Finally, the two external end terminations are added. To guarantee optimum solderability the outer layer consists of a lead-tin alloy. * Telecom * Consumer.

The test condition for no leaching is 260 C for 60 seconds. Typical examples of soldering processes that provide reliable joints without any damage, are given in Figs 5 and 6. The robust construction of chip resistors allows them to be completely immersed in a solder bath of 260 C for one minute. Therefore, it is possible to mount surfacemount resistors on one side of a PCB and other components on the reverse side (mixed PCBs). 300 MLA859 10 s T 260 C 245 C (C) 250 10 s 215 C 200 180 C 150 40 s 130 C 100 2 K/s 50 0 0 50 100 150 200 250 t (s) Typical values (solid line).
