METAL OXIDE RESISTORS

Metal Oxide Resistors

RSS, RSN

Tokenchina resistor product line includes metal oxide (RSN) and reduced size metal oxide (RSS) power type leaded resistors.


Tokenchina's metal oxides are designed with a flame retardant coating over a metal oxide film deposited on a ceramic core. Lower values are available in both the RSN and RSS series.


With a high reliability for performance they are suitable for automatic machine insertion. Various types of taping and forming are offered, including Axial Stand-off, Axial, Radial, and M, MB, F, FK forming. Tape & Reel or bulk packaging is also available.


Tokenchina's RSS, RSN Series RoHS compliant metal oxide power type resistor is utilized for both general (RC timing circuits, voltage divider, and pull-up/pull-down resistors) and surge (RC snubber circuits, current limiting, overload ground line) applications in the automotive, industrial and consumer industries.
