BCcomponents DATA SHEET MRS16 MRS25 Professional leaded resistors Maintenance types (not for new designs) 2000 Sep 06 File under BCcomponents, BC08BCcomponents Maintenance types (not for new designs) Professional leaded resistors MRS16 MRS25 FEATURES DESCRIPTION Professional resistors in small outlines A homogeneous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in Low noise. 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 climatic protection. Four or five colour code rings designate All general purpose applications. the resistance value and tolerance according to IEC 60 062. Suitable replacements for MRS16 and MRS25 are the MBA 0204 and MBB 0207 professional.
