Power Wire Wound Chip Resistors (SMW) Molded Type

When the current through the resistance element, the heat generated. And the temperature change causes mechanical changes by expansion or contraction in each material involved in the components. Thus, the ideal resistor element incorporates these natural phenomena into a self-balanced stability enhancement system which maintains its physical integrity through the resistor manufacturing process and eliminates the need to compensate for the effects of heat or stress during use.

DeMint Electronics (SMW) Chip Series Precision Power Wound Resistors are specifically designed to meet the ever-increasing surface mount resistor requirements and provide high precision power, compact, reliable, and rugged performance. Compared with the surface temperature rise of other SMD power resistors, (SMW) thermal design has been optimized to provide greater thermal efficiency.

Power wirewound Chip Resistor (SMW) series includes 2W, 3W and 5W three kinds of power. Resistance range from 0.1Ω to 680Ω and accuracy tolerance options are 1%, and 5% with low TCR and high overload capacity, suitable for surge and pulse applications.

When the first release of enhanced power handling capability, the 3W and 5W (5% tolerance) versions are SMD resistors, DeMint setting a new high power standard. At present, it is still one of the most powerful chip resistors on the market. Power wirewound Chip Resistors (SMW) series optimize thermal design to provide higher efficiency and higher surge capacity while reducing surface temperature rise and long-term thermal damage to PCB boards and adjacent electronic components.

Surface Mount (SMW) Series is available in tape, RoHS compliant and 100% lead free. For conventional parameters, specifications outside the parameters, or technical requirements, please contact DeMint. Download PDF version Power Wire Wound Chip Resistors.
