DESCRIPTION

MBA/SMA 0204, MBB/SMA 0207 and MBE/SMA 0414

professional leaded thin film resistors are the general

purpose resistor for all fields of professional electronics

where reliability and stability is of major concern. Typical

applications include industrial, telecommunication and

medical equipment.

FEATURES

• Approved according to CECC 40101-806

• Advanced thin film technology

• Power dissipation rating up to 1 W

• Excellent overall stability: class 0.25

• Wide professional range: 0.22 Ω to 22 MΩ

• 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)

APPLICATIONS

• Industrial

• Telecommunication

• Medical equipment

Note:

MB_ series has been merged with the related SMA series to form one series “MB_/SMA__”.
