DESCRIPTION

Production of the CMB 0207 specialty MELF resistor 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 (Al

). Nickel plated steel termination caps are firmly

pressed on the coated rods. Products with a resistance of

15  or lower are made without trimming, whereas a special

laser is used to achieve a target value of 16  or above

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 matte tin on nickel plating. Four or five

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.
