| MRS16, MRS25 Vishay BCcomponents Professional Leaded Resistors FEATURES * Professional resistors in small outlines * Low noise. APPLICATIONS * All general purpose applications. DESCRIPTION A homogeneous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in the resistive layer, tinned connecting wires of electrolytic copper are welded to the end-caps. The resistors are coated with lacquer which provides electrical, mechanical, and climatic protection. Four or five colour code rings designate the resistance value and tolerance according to IEC 60 062. The resistors are completely lead-free, the pure tin plating provides compatibility with lead-free and lead-containing soldering processes. Suitable replacements for MRS16 and MRS25 are the MBA 0204 and MBB 0207 professional.
