DESCRIPTION

Production of the CMA 0204 specialty MELF resistors with

advanced pulse load capability is strictly controlled and

follows an extensive set of instructions established for

reproducibility. A homogeneous and dense carbon film is

deposited on a high grade ceramic body (85 % Al

Nickel plated steel termination caps are firmly pressed on

the coated 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 resistors are

covered by protective coating designed for electrical,

mechanical and climatic protection.The terminations receive

a final pure matte tin on nickel plating. Four color code rings

designate the resistance value and tolerance in accordance

with IEC 60062

(1)

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,

Type 2a

(1)

ASSEMBLY

The resistors are suitable for processing on automatic SMD

assembly systems. They are suitable for automatic

soldering using wave, reflow or vapor phase as shown in

IEC 61760-1

(1)

. Solderability is specified for 2 years after

production or requalification, however, excellent

solderability is proven after extended storage in excess of

10 years. The permitted storage time is 20 years.

The resistors are completely lead (Pb)-free, the pure matte

tin plating provides compatibility with lead (Pb)-free

soldering processes. The immunity of the plating against tin

whisker growth has been proven under extensive testing.

The encapsulation is resistant to all cleaning solvents

commonly used in the electronics industry, including

alcohols, esters and aqueous solutions. The suitability of

conformal coatings, potting compounds and their

processes, if applied, shall be qualified by appropriate

means to ensure the long-term stability of the whole system.
