Anti-Surge Wirewound Fast-Fuse MELF Resistor 1W 3.3ohm 5% / More than 50 years of resistor manufacture experience

Manufacturer of Fusible resistor, SMD resistor. Anti-Surge Wirewound Fast-Fuse MELF Resistor 1W 3.3ohm 5% is the same as SWM series, but specially add fusible function on it. 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. FIRSTOHM is one of the few companies who is able to design thin-film resistors according to customer's requirements with high quality and reliability. We’re specialized in MELF resistors since 1969, ISO9001/14001 certificated manufacturer.

Surge Power Derating Curve
Anti-Surge Wirewound Fast-Fuse MELF Resistor - SWMT 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.
