DESCRIPTION
A homogenous 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 a grey, flame retardant lacquer which provides electrical, mechanical, and climatic protection. The encapsulation is resistant to all cleaning solvents in accordance with “MIL-STD-202E, method 215”, and IEC 60068-2-45”.

FEATURES
*Overload protection without risk of fire
*Wide range of overload currents (refer Fusing Characteristics graphs)
*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
*Audio
*Video

DESCRIPTION
 MBA 0204, MBB 0207 and MBE 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.
Production is strictly controlled and follows an extensive set of instructions established for reproducibility.
A homogeneous film of metal alloy is deposited on a high grade ceramic body (85% Al2O3) and conditioned to achieve the desired temperature coefficient.
Nickel plated steel termination caps are firmly pressed on the metallised rods.
A special laser is used to achieve the target value by smoothly cutting a helical groove in the resistive layer without damaging the ceramics.
Connecting wires of electrolytic copper plated with 100% pure tin are welded to the termination caps.
The resistor elements are covered by a light blue protective coating designed for electrical, mechanical and climatic protection.
Four or five colour code rings designate the resistance value and tolerance in accordance with IEC 60062.
The result of the determined production is verified by an extensive testing procedure performed on 100% of the individual resistors.
Only accepted products are stuck directly on the adhesive tapes in accordance with IEC 60286-1.
The resistors are suitable for processing on automatic insertion equipment and cutting and bending machines.
Excellent solderability is proven, even after extended storage.

DESCRIPTION
 Production is strictly controlled and follows an extensive set of instructions established for reproducibility. A homogeneous film of metal alloy is deposited on a high grade ceramic body (85 % Al2O3, for MICRO-MELF: 96 % Al2O3) and conditioned to achieve the desired temperature coefficient. Nickel plated steel termination caps are firmly pressed on the metallised rods. A special laser is used to achieve the target value by smoothly cutting a helical groove
in the resistive layer without damaging the ceramics. The resistor elements are covered by a protective coating designed for electrical, mechanical and climatic protection.

 The terminations receive a final pure tin on nickel plating. Four or five colour code rings designate the resistance value and tolerance in accordance with IEC 60062*.
The result of the determined production is verified by an extensive testing procedure performed on 100 % of the individual resistors. Only accepted products are laid directly into the blister tape in accordance with IEC 60286-3* or bulk case in accordance with IEC 60286-6*.
