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 energy, so to prevent hazard of circuit damage caused by surge energy
Application
- Lighting Device
- 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.
Surge Power Derating Curve
• 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.
