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
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 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.
• Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
• Compatible to RoHS directive 2002/95/EC
APPLICATIONS
• All general purpose applications
