Features
  • Designed to replace carbon or ceramic composition resistor, SSR series is applied in high-surge applications such as fuel ignition systems, power charging/discharging circuits, TV sets, etc, to absorb harmful surge energy, so to prevent hazard of fire and circuit damage caused by surge energy with a flame-proof coating.
  • Products meet RoHS requirements and do not contain substances of very high concern identified by European Chemicals Agency
Application
  • Industrial Automation
  • Measurement/Testing Equipment
  • Power Supply
  • Medical equipment
  • ECG Cable
Single Surge Performance
Surge Safety Resistor-SSR series,is showing the surge performance from 10uS to 1S.
Surge Safety Resistor-SSR series,is showing the surge performance from 10uS to 1S.

Surge Power Derating Curve
Surge Safety Resistor-SSR 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.
