LEADED TYPE FIXED RESISTORS
Carbon Film Fixed Resistors
Fixed resistors with excellent pulse resistance that use a carbon film as a resistive element, and have long been the most popular resistor. In terms of electric power, 1/4 W and 1/2 W types are the most common in the marketplace. Small types such as 1/4W type of 3.2 mm x 1.9 mm size and 1/2 W type of 6.3 mm x 2.85 mm size are mainstream and widely used as general-purpose products.
Metal Film Fixed Resistors
Fixed resistors with a metal film as a resistive element, which provides small resistance tolerance, T.C.R., less aging variation, high accuracy, excellent stability and low current noise. The main applications include industrial equipment such as telecommunication and measuring equipment, as well as automobiles and sensor modules, which require the high precision for circuits to handle minute signals.
Metal Oxide Film Fixed Resistors
Fixed resistors with a metal oxide film as a resistive element, which provides high power rating in a small size (the smallest volume per rated power among all the resistors), and an excellent heat resistance. Low T.C.R. is achievable at a lower cost compared to power type metal film resistors. The main application is power supply circuit.
WIREWOUND FIXED RESISTORS
Fixed resistors with a metal resistive wire as a resistive element. It has excellent pulse resistance and heat resistance. Its low T.C.R. achieves the low current noise. On the other hand, it is difficult to obtain a high resistance value, and the winding structure makes it unsuitable for high-frequency circuits. Wirewound resistors are mainly used as a pre-charge resistor in power supply circuits. These resistors with low resistance are used for current sensing.
