Notes

Avoid the use of those cleaning agents that could attack epoxy resins, which form part of the resistor construction.

Vacuum pick-up is recommended for handling.

Soldering iron not recommended.

HARMONIC DISTORTION

Harmonic distortion is an important consideration in the

choice of precision resistors for sensitive applications. A

significant signal voltage across the resistor may change

the resistance value depending on the construction,

material, and size. Under these conditions Bulk Metal Foil

resistors behave more linearly than other resistor types.

FLOWER OF SULFUR

ASTM B 809, also known as flower of sulfur, is a test to

determine the porosity of metallic coating using humid

sulfur vapor. This vapor can penetrate conformal coatings

and cause damage to the device when it reacts with

lower layers of silver. Surface-mount Bulk Metal Foil chip

resistors avoid this problem with a special coating that

is proven to be reliable in extreme environments and

even against sulfur. The flower of sulfur test is especially
