Single Surge Performance
Anti-Surge Wirewound Resistor - SWA 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.

Surge Safety Resistor-SSR
The Surge Safety Resistor (SSR series) features a power rating from 0.25W to 5W, with resistance ranging from 10 ohm to 330K ohm. Designed to replace carbon or ceramic composition resistors, the SSR series is a good choice for anti-surge applications such as fuel ignition systems, power charging/discharging circuits, and ECG cables to absorb harmful surge energy, thereby preventing the hazard of fire and circuit damage caused by surge energy with a flameproof coating. Products comply with RoHS requirements and do not contain substances of very high concern identified by the European Chemicals Agency.
Fusible Fixed Resistor-FGE
Fusible Resistor (FGE series) with axial leaded type, features a power rating from 0.25W to 3W, resistance range from 2.2 ohms to 15K ohms, and flameproof feature equivalent to overload test UL 1412. The fusible resistor is a special resistor made to protect every circuit.
Anti-Surge Wire Wound MELF Resistors-SWM
The Anti-Surge Wire Wound MELF Resistor (SWM) features a power rating from 1W to 4W, with resistances ranging from 1 ohm to 1.2K ohm, and tolerance of ±1%, ±2%, and ±5%. The SWM series is applied in high surge applications such as high rush current protection for power capacitors, motor start-up protection, Electric Vehicle, renewable energy storage, etc., to absorb harmful surge energy, thereby preventing the hazard of circuit damage caused by surge energy. Due to its SMD-enabled structure with MELF style, it is better in heat dissipation than chip resistor, and it has a stronger mechanical structure to endure vibration and thermal shock. The electrodes are enhanced to weld more reliably against surge.
