Features
  • Application: high-frequency, sharp-impulse circuits.
  • To protect active components in missile detonators, triac switching circuits, etc.
  • Offer every better aspect of performance than carbon composition resistor.
  • No "sintering effect" caused by high surge that greatly decreases resistance value.
  • Replaces carbon composition resistor.
  • Conformal multi-layer non-flammable coating.
  • Products meet RoHS requirements and do not contain substances of very high concern identified by European Chemicals Agency
Application
  • Power Supply
  • Telecomm
  • Meter
  • Medical
Single Surge Performance
Pulse Protective Resistor - PPR series,is showing the surge performance from 10uS to 1S.
Pulse Protective Resistor - PPR series,is showing the surge performance from 10uS to 1S.

Surge Power Derating Curve
Pulse Protective Resistor - PPR 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.
