PRODUCT HISTOR Y:

PRODUCT DESCRIPTION:

The CHP Surf ace Mount Resistor Series is a member of the RG

product family of precision Metal Glaze™ Resistors. The Metal

Glaze™ technology, developed b y IRC in 1960 to meet the strin-

gent demands of the Military mar ket, provides an unsurpassed

combination of ruggedness, performance, and low cost. Since

its development, IRC has supplied billions of units to meet the

specific requirements not only of the Military, but also to all major

users of resistive components requiring reliability, service, and

quality at a reasonable price. Proven reliability of the Metal

Glaze™ resistor family is supported by well over a billion unit

hours of life testing with no failures.

The CHP is a precision surface mount power resistor. Its cylin-

drical shape is composed of a Metal Glaze™ resistive element

fired onto a ceramic core with capless solder terminations. The

simplicity of design and construction, provide a cost effective

solution to common applications where reliability is a major con-

cern, and also offer some unique features to surf ace mount tech-

nology.

The CHP uses a cylindrical high alumina ceramic for the core

of the resistor. This substrate provides excellent thermal con-

ductivity for maximum power dissipation in a minimum of board

real estate. It also provides superb mechanical strength to eas-

ily withstand stresses presented during board assembly, mount-

ing, and operation.

The Metal Glaze™ is composed of glass and metal par ticles

which are fired onto the ceramic substrate at approximately

1000°C. This technology provides a resistive element that is im-

pervious to environmental conditions without the need f or an air-

tight encapsulation. The inherent ruggedness of this glaze can

absorb higher voltage surges and overloads than "thin-film" coun-

terparts.

To ter minate the CHP, an electroless nickel barr ier is applied

to the termination area. Solder is then applied by hot-solder

dipping. This technique provides reliable electrical continuity

through the termination without the use of end-caps or weld joints.

Unlike the typical "MELF", there is no "dog-bone" shape result-

ing from end-caps to interfere with "pick and place" accuracy.

The solder termination is free of silver to provide superb solder-

ability performance on both reflow and wa ve soldering processes.

The CHP Resistor was developed in 1980 by IRC to support the

automotive mo ve toward surf ace mount technology . The CHP uses

the same highly reliable Metal Glaze™ technology and materials

as its leaded counterpart. The termination and encapsulation hav e

been modified to provide compatibility with surf ace mount technol-

ogy. Since its development, the CHP has proven its reliability and

service record by becoming a "World Class Product" supporting

the surface mount needs of the A utomotiv e , Computer , Instrumen-

tation, Telecommunication, and other industrial electronics mar-

ket.

CHP FAMILY STANDARD SIZES, SOLDER PADS AND PA CKAGING:

RECOMMENDED SOLDER PAD DIMENSIONS (REFLO W):

To ensure excellent solderability performance, IRC recommends the following pad design. This design will provide a

large repeatable solder fillet to the CHP resistor on reflow processes and will provide maximum heat transfer to the PC

board in high power applications. By placing the CHP on the solder paste while the paste is in the "tac ky" state, the CHP

will be held in position until solder reflow begins. The pad design then uses the surface tension of the molten solder to

pull the component to the center of the solder pad. The placement of a via rising abov e the board le v el directly beneath

the CHP is not recommended.
