DESCRIPTION

MMU 0102, MMA 0204 and MMB 0207 professional thin

film MELF resistors are the perfect choice for most fields of

modern professional electronics where reliability and

stability is of major concern. The typical applications in the

fields of automotive, telecommunication and medical

equipment reflect the outstanding level of proven

reliability.

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 60 062.

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 60 286-3 or bulk

case in accordance with IEC 60 286-6.

The resistors are suitable for processing on automatic SMD

assembly systems. They are suitable for automatic soldering

using wave, reflow or vapour phase. Excellent solderability

is proven, even after extended storage in excess of 10 years.

The encapsulation is resistant to all cleaning solvents

commonly used in the electronics industry, including

alcohols, esters and aqueous solutions.

The resistors are completely lead-free, the pure tin plating

provides compatibility with lead-free soldering processes.

The immunity of the plating against tin whisker growth has

been proven under extensive testing. All products comply

with the CEFIC-EECA-EICTA list of legal restrictions on

hazardous substances.

The resistors are tested in accordance with

EN 140 401-803 (superseding CECC 40 401-803) which

refers to EN 60115-1 and EN140 400. Approval of

conformity is indicated by the CECC logo on the package

label.

BCcomponents BEYSCHLAG has achieved "Approval of

Manufacturer" in accordance with EN 100 114-1. The

release certificate for "Technology Approval Schedule" in

accordance with CECC 240 001 based on EN 100 114-6 is

granted for the BCcomponents BEYSCHLAG manufacturing

process.

This product family of thin film MELF resistors is completed

by Zero Ohm Jumpers.

On request, resistors are available with established

reliability in accordance with EN 140 101-803 Version E.

Please refer to the special data sheet for information on

failure rate level, available resistance ranges and ordering

codes.

QUICK REFERENCE DATA

Notes

1. The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heatflow

support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film

temperature is not exceeded. Furthermore, a high level of ambient temperature or of power dissipation may raise the

temperature of the solder joint, hence special solder alloys or board materials may be required to maintain the reliability

of the assembly.

2. Specified power rating requires dedicated heat-sink pads.

TESTS AND REQUIREMENTS

All tests are carried out in accordance with the following

specifications:

EN 60 115-1, generic specification

EN 140 400, sectional specification

EN 140 401-803, detail specification

The components are approved in accordance with the

European CECC-system, where applicable. For the full test

schedule refer to the documents listed above. The testing

also covers most of the requirements specified by EIA/IS-703

and JIS-C-5202.

The tests are carried out in accordance with IEC 60 068 and

under standard atmospheric conditions in accordance with

IEC 60 068-1, 5.3. Climatic category LCT/UCT/56 (rated

temperature range: Lower Category Temperature, Upper

Category Temperature; damp heat, long term, 56 days) is

valid.

Unless otherwise specified the following values apply:

Temperature: 15 °C to 35 °C

Relative humidity: 45% to 75%

Air pressure: 86 kPa to 106 kPa (860 mbar to

1 060 mbar).

The components are mounted for testing on printed-circuit

boards in accordance with EN 140 400, 2.3.3, unless

otherwise specified.

The requirements stated in Table 5 are based on the required

tests and permitted limits of EN 140 401-803. However,

some additional tests and a number of improvements against

those minimum requirements have been included. The

stated requirements for long-term tests are typically fulfilled

with a statistical safety of at least +5 s.x
