H44K75DZA

Through Hole Resistors

A through hole resistor is a type of resistor, a passive two-terminal electrical component, used to manage the current in electronic circuits. The term through hole resistor derives from the fact that the resistor is manufactured with a hole drilled through one side of its body. Because the hole allows the resistor to be placed and affixed more easily, the through hole resistors have found increasing use in recent years for a variety of applications, some of which are detailed below.

H44K75DZA Application Field and Working Principle

The H44K75DZA is a through-hole resistor used to manage power in power supplies, signal amplifiers, analog circuits, digital circuitry, and other applications. The resistor has a nominal impedance of 75 ohms, meaning its electrical properties allow it to resist a current rise of 75 ohms (or less) under normal operating conditions. It is available in a variety of packages and three different resistance ratings: 75 ohms, 100 ohms, and 1 ohm. The resistor is constructed from a ceramic base material which helps to make it highly temperature resistant.

The resistor is made using a two-terminal design which helps to make power management in the device efficient. The two terminals of the resistor are connected to the power source which sends the current to be regulated. When the current reaches the resistor, it is diminished in magnitude and then sent to the next component in the circuit. The size of the current is determined by the value of resistance used. Higher resistance values result in lesser amounts of current being sent to the next component.

The resistor is designed to be used in close proximity to its target component, and the insulation of the resistor allows it to operate reliably in higher temperatures. This insulation helps to reduce the effects of heat, which can cause the resistor to experience power fluctuations. The resistor also features a built-in heat sink which helps to wick away heat away from the resistor and minimize any fluctuations due to thermal expansion.

Due to its power-management qualities and robust durability, the H44K75DZA through hole resistor is well-suited for a variety of applications including power management in audio-visual equipment, power supplies, and analog-to-digital converters. It is also suitable for applications that require very low power consumption, such as automotive electronics. Also, its small size and easy installation make it an attractive option for high-density PCBs.
