Anti-Surge Wirewound MELF Resistor-X series ( 1W 51ohm 5%)
SWM100XJ51R0TKZTR2K5
high pulse load resistor, SMD resistor
Anti-Surge Wirewound MELF resistors-X series(SWMX) have positive temperature coefficient characteristics that are resistant to surges, and the resistance value will increase as the temperature rises. it's used in electric instruments where anti-surge and power dissipation are required. Multi-national patents are approved.
Anti-Surge Wirewound MELF Resistor-X series 1W 51ohm 5% is designed by winding metal alloy wire around the superior ceramic rod, it can operate in high temperature with long-term stability.
