Higher component and equipment reliability 5. RoHS exemption free and Lead free products APPLICATION Consumer electrical equipment Automotive application EDP, Computer application Telecom application DESCRIPTION The LEAD FREE resistors are constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are added at each end and connected by a LEAD FREE 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. For all series, Overcoat is water blue color. Finally, the two external end terminations are added. For ease of soldering the outer layer of these end terminations is a Tin ( LEAD FREE ) alloy. Fig 1. Construction of a Chip-R Page 2 of 8 ASC WR TR (Pb<100ppm) V07 Nov - 2014
