Approval sheet WR12, WR08, WR06, WR04 ±1%, ±5% Thick Film General Purpose Chip Resistors Size 1206, 0805, 0603, 0402 *Contents in this sheet are subject to change without prior notice. Page 1 of 10 ASC_WR_V23 APR.- 2015 Approval sheet FEATURE 1. High reliability and stability 2. Reduced size of final equipment 3. Lower assembly costs 4. Higher component and equipment reliability 5. RoHS compliant and Lead free products APPLICATION • Consumer electrical equipment • EDP, Computer application • Telecom application DESCRIPTION The resistors are 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 Tin (lead free) alloy. Fig 1.
