Metal Oxide Resistors on The Pulse
in Various Forming Styles for Different Applications
Preview
Now available from Token Electronics is a new range of highly stable and reliable metal oxide resistors
providing high power in a small package with various forming styles and different leads for different
applications.
New RS series resistors are ideal for pulse applications in adverse conditions and are available in different sizes
with power ratings of 0.5W to 10W for a power voltage range from 200V to 850V. Highly temperature resistant
the devices feature a resistance range from 10Ω to 47KΩ.
RS series resistors are available in various forming styles and different leads for different applications like power
supplies, amplifiers, household appliances and ballasts.
Manufactured by depositing a homogeneous oxide film of metal alloy onto a high-grade ceramic body, the metal
oxide resistors are coated with a nonflammable lacquer providing mechanical, electrical and climatic protection.
The devices come packaged in ammo pack boxed or tape and reel format. All RS Series devices are RoHS-
compliant, and compatible with high temperature soldering processes normally employed for lead free solders.

Application Notes
RSS, RSN Metal Oxide Resistors
● Never use organic solvents to clean non-flammable resistors.
● Maintaining a surface temperature of 200°C or less will extend resistors service life.
● Although the hardness exceeds that of a 3H pencil lead, do not nick the coating with screwdrivers
or other pointed objects.
● Smoke emitted from non-flammable resistors on initial use in powered circuits is a normal
phenomenon and the component can be safely utilized.
● Non-flammable resistors cannot be utilized in oil. Non-flammable resistors cannot be used in high
frequency machinery because of the inductance produced by the grooving.
● Avoid touching non-flammable resistors in operation; the surface temperature ranges from
approximately 350 °C to 400°C when utilized at the full rated value.
● All metal oxide film resistors (RSS, RSN) manufactured by Token Electronics Co., Ltd. comply
with the U.S. UL-94 non-flammability test, Class V-0, a continuous combustion period of zero seconds.
● Less resistant against external shocks than ordinary resistors due to special flame retardant coating.
So, never give shocks or vibrations on the resistors. Also never damage them by picking up the
coated films with pliers, tweezers, etc.
● After cleaning, no external power should be put on the coated films before they are well dried.
