Comparison Between Metal Plate & Ceramic Type Hvac Motor Control Resistors

Simply put, these are tailor made resistors having 3 distinct resistance values which translates into controlling the Blower Motor speeds of an Automotive Air-conditioner. These resistors are mounted in the Air Flow of the Air-conditioner module and the reason behind this is, to keep the resistor as cool as possible. In the case of a […]

Techno/Economic Comparison Between Silicon/Cement Coated Wire Wound Resistors And Ceramic Encased Resistors

Traditionally Wire Wound Resistors meant coated resistors of either silicon or vitreous enameled on a Ceramic body which was wound with resistance wire which was welded or soldered to the terminals and these types of resistors were termed as professional or industrial grade Wire Wound Resistors. However in the mid 1970’s there was a demand […]

Why Are Capacitor Discharge Resistors Now Mandated As Essential Safety Device

In Electronics, Capacitor discharge resistors or Bleeder resistors are resistors connected in parallel with the output of a high voltage power supply circuit with the express purpose of discharging the residual electric charge stored in the filter capacitors of the power supply. As an example, a switch mode power supply uses a bridge rectifier to […]

Comparative advantage of Wire Wound Technology over Film Technology in Fusible Resistor applications

Fuse Resistors serve a dual purpose, as a resistor and also a fuse. They are designed so that they will open with a large surge of current without any flame or other untoward incident.Fusible film resistors are generally used for lower power requirements and applications where the overload and surge handling requirements are not too […]

Application / Design Notes on Selection of Wirewound Resistor

BASICS Simply put, a resistor is an electronic component connected into an electrical circuit to insert a specific resistance. Resistance is measured in ohms and as per ohms law, the current through the resistor will be directly proportional to the voltage across it and inversely proportional to the resistance. As the current flows through the […]
