MRS16, MRS25 Vishay BCcomponents Professional Leaded Resistors FEATURES • Professional resistors in small outlines • Low noise • Lead (Pb)-free solder contacts • Pure tin plating provides compatibility with lead (Pb)-free and lead containing soldering processes • Compatible with “Restriction of the use of Hazardous Substances” (RoHS) directive 2002/95/EC (issue 2004) DESCRIPTION APPLICATIONS 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. Suitable replacements for MRS16 and MRS25 are MBA/SMA 0204 and MBB/SMA 0207 professional. • All general purpose applications TECHNICAL SPECIFICATIONS VALUE DESCRIPTION Resistance Range MRS16 MRS25 4.99 Ω to 1 MΩ 1 Ω to 10 MΩ Resistance Tolerance and Series ± 1 %; E24/E96 series Maximum Dissipation at Tamb = 70 °C Thermal Resistance (Rth) 0.4 W 0.6 W 170 K/W 150 K/W Temperature Coefficient ± 50 ppm/K Maximum Permissible Voltage (DC or RMS) 200 V Basic Specifications 350 V IEC 60115-1 and 60115-2 Climatic Category (IEC 60068) 55/155/56 Max.
