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
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.
• Low noise.
APPLICATIONS
• All general purpose applications.
Suitable replacements for MRS16 and MRS25 are the
MBA 0204 and MBB 0207 professional.

ORDERING INFORMATION
Numeric Ordering code (12NC)
• The resistors have a 12-digit ordering code starting with 2322 15.
• The subsequent 2 digits indicate the resistor type and packaging; see Table 1.
• The remaining 4 digits indicate the resistance value:
– The first 3 digits indicate the resistance value.
– The last digit indicates the resistance decade in accordance with Table 2.
