MRS16, MRS25 Vishay BCcomponents Professional Thin Film Leaded Resistors FEATURES Technology: Metal film Professional resistors in small outlines Low noise Lead (Pb)-free solder contacts DESCRIPTION Pure tin plating provides compatibility with lead (Pb)-free and lead containing soldering processes A homogeneous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in Compatible to RoHS Directive 2002/95/EC the resistive layer, tinned connecting wires of electrolytic copper are welded to the end-caps. The resistors are coated APPLICATIONS with lacquer which provides electrical, mechanical, and All general purpose applications climatic protection. Four or five color code rings designate the resistance value and tolerance according to IEC 60062. Suitable replacements for MRS16 and MRS25 are MBA/SMA 0204 and MBB/SMA 0207 professional.
