Anti-Surge Wirewound Fast-Fuse MELF Resistor( 3W 20ohm 5%)
SWMT300J20R0TKZBK500
Fusible resistor, SMD resistor
Anti-Surge Wirewound Fast-Fuse MELF Resistor(SWMT) 3W 20ohm 5% is the same as SWM series, but specially add fusible function for SWMT series, it can operate at high temperature with long term stability. Anti-Surge Wirewound Fast-Fuse MELF Resistors are used in the electric instruments where anti-surge and fusible function are required.

Single Surge Performance
Anti-Surge Wirewound Fast-Fuse MELF Resistor - SWMT 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.
