Small size and light weight 2. Reduced size of final equipment 3. Lower surface mounted assembly costs 4. Higher component and equipment reliability 5. Lead (Pb) free terminations is available. APPLICATION * Consumer electrical equipment * EDP, Computer application * Telecom DESCRIPTION The resistors array is constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are added at each end and connected by a resistive paste that 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. The resistive layer is covered with a protective coat. Finally, the two external end terminations are added. For ease of soldering the outer layer of these end terminations is a Lead-tin or Tin (Pb free) solder alloy. Fig 1.

For values up to 91 the R is used as a decimal point. For values of 100 or greater the first 3 digits apply to the resistance value and fourth indicate the number of zeros to follow.

Maximum dissipation in percentage of rated power As a function of the ambient temperature MOUNTING Due to their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by automatic placement systems. Chip placement can be on ceramic substrates and printed-circuit boards (PCBs). Electrical connection to the circuit is by individual soldering condition. The end terminations guarantee a reliable contact. Page 4 of 7 WA06X_D Version 04 Dec.-2006 Walsin Technology Corporation SOLDERING CONDITION The robust construction of chip resistors allows them to be completely immersed in a solder bath of 260C for one minute. Therefore, it is possible to mount Surface Mount Resistors on one side of a PCB and other discrete components on the reverse (mixed PCBs). Surface Mount Resistors are tested for solderability at 235C during 2 seconds. The test condition for no leaching is 260C for 60 seconds. Typical examples of soldering processes that provide reliable joints without any damage are given in Fig 3. Fig 3.
