Through Hole Resistors – H4215KBZA Application Field and Working Principle

Through-hole resistors are fundamental electronic components which may be used in a range of low- to medium-power applications. The particular model in the title—the H4215KBZA—is a small- to medium-sized, Quick Connect through-hole resistor able to either solder or plug in. It has a total resistance range of 0.1 to 47k ohms, and a power rating of .5 watts. The H4215KBZA is available with a number of resistive values, up to a maximum of 47k ohms, a typical tolerance of ± 10%, and a temperature coefficient of ± 800 ppm/°C.

The H4215KBZA can be applied in multiple industrial and consumer electronics applications, such as instrumentation, television sets, clocks, lighting, computers, amplifiers, and telecom modules. Given its maximal power rating of .5 watts and wide resistance range, it is particularly suitable for controlling temperature, amperage, lighting, signals, and power, as well as providing noise or surge-protection in quite simple circuits.

The precise working principle of the H4215KBZA is to limit the amount of current which flows in an electronic circuit. This is a vanadium-based resistor design, allowing low- to medium-power applications using a single through-hole resistor. The H4215KBZA is a single-inline ceramic resistor, offering a robust construction, long lifespan, and excellent moisture resistance.

The basic design of the H4215KBZA is a resistor body with leads protruding from either end, and small notches at either end to facilitate wire connections. The resistor can be quick connected or soldered into place. To do this, the installer must simply strip the wire’s insulation to expose the conductor, insert it into one notch, and then curl the other wire over the other notch. Alternately, the technician can solder the resistor into place.

When in active use, the resistor has a particular resistance, a value measured in ohms. This resistance divides the current into several directions, with more or less energy precisely calculated depending on the level of resistance chosen. As a result, current is “limited”, prevented from damaging any of the other electronics components in the circuit.

By virtue of its design and physical parameters, the H4215KBZA is an affordable, cost-effective component for simple applications, and flexible enough to be used in all kinds of electronic systems. Its solder or plug-in construction allows it to fit almost any size circuit, and its nominal power rating of .5W, along with its temperature coefficient of ± 800ppm/°C, provides quite adequate protection and performance to a wide range of home and industrial electronics applications.
