Features
  • AEC-Q200 Compliant
  • SMD enabled structure
  • Heat dissipation is much better than chip resistor
  • Stronger mechanical structure to endure vibration and thermal shock
  • Flameproof multi-layer coating equivalent to UL 94 V-0
  • Flameproof feature equivalent to overload test UL 1412
  • Enhanced weld spot is reliable against surge
  • Products meet RoHS requirements and do not contain substances of very high concern identified by European Chemicals Agency
  • SWM series is applied in high surge applications such as high rush current protection for power capacitor, motor start-up protection, car & motorcycle engine ignition, etc. to absorb harmful surge, so to prevent hazard of circuit damage caused by surge
Application
  • Lightning protection
  • Motor start up protection
  • Power Supply & power adaptor
  • High inrush current protection for power capacitor
  • Industrial Automation
Single Surge Performance
Anti-Surge Wirewound MELF Resistor - SWM series, is showing the surge performance from 10uS to 1S.
Anti-Surge Wirewound MELF Resistor - SWM series, is showing the surge performance from 10uS to 1S.

Surge Power Derating Curve
Anti-Surge Wirewound MELF Resistor - SWM series, the surge performance between single and repetitive surge.
• SINGLE SURGE PERFORMANCE graph is good for NON REPETITIVE applications operating in an ambient temperature of 70°C or less. For temperatures above 70°C, the graph power must be derated further linearly down to zero at 150 °C.
• To determine applicable surge power in continuous-surge applications:
1. Identify allowable duration and peak power Psurge of single surge.
2. Determine ratio of surge duration/surge OFF time in application.
3. Calculate Papplicable backwardly according to Y-axis of SURGE POWER DERATING CURVE.
