Introduction to H4681KBZA Through Hole Resistors

Through hole resistors (THRs) are electrical components used to control the flow of electricity in a circuit. They are among the most fundamental electronic components, and are widely used in a variety of circuits. THRs come in a variety of shapes, sizes, and values. One such THR is the H4681KBZA, a surface-mounted mono-capped THR. This article will describe the application field and working principle of the H4681KBZA THR.

Application Field of the H4681KBZA THR

The H4681KBZA through-hole resistor is a versatile component, suitable for use in a number of different applications. It is most commonly used in control systems, where precise and repeatable resistor values are needed. The H4681KBZA is also suitable for use in power supplies, lighting circuits, and signal conditioning, as well as a variety of other applications.

Working Principle of the H4681KBZA THR

The H4681KBZA THR is a mono-capped THR, meaning that it has a single contact on the top surface. This contact is connected to both the resistor element and the wire, and thus acts as a bridge between them. When electricity passes through the THR, it splits in two when it encounters the resistor element, with a certain portion of the current passing through the resistor and the remainder bypassing the device. This is the principle on which the H4681KBZA THR operates.

Mechanical Characteristics of the H4681KBZA THR

The H4681KBZA THR is a surface-mounted component, meaning that it can be mounted on the surface of a circuit board. It is small and lightweight, and comes in a variety of sizes, with solder paddle widths ranging from 0.2mm to 0.4mm. The THR also has a low profile, which makes it suitable for use in compact and space-saving designs.

Electrical Characteristics of the H4681KBZA THR

The H4681KBZA THR is a low resistivity device, with an effective resistance range of 0.1 Ω to 10 MΩ. It also has a low voltage coefficient, meaning that its resistance remains relatively constant over a wide range of applied voltages. The THR has a high tolerance rating of +/- 10%, meaning that the actual value of the resistor may vary from its marked value by up to 10%.

Environmental Characteristics of the H4681KBZA THR

The H4681KBZA THR is well suited to use in a variety of environmental conditions. It is constructed of high-temperature materials, ensuring that it remains stable even in high-temperature environments. It also has a wide operating temperature range of between -55°C and +125°C, making it suitable for use in a range of extreme environments.

Conclusion

The H4681KBZA THR is a versatile and reliable THR, suitable for use in a variety of applications, from control systems to power supplies. It has a low profile, low resistivity, and a wide operating temperature range, making it a reliable and versatile component. The THR also has a high tolerance rating, ensuring that the actual value of the resistor may differ from its marked value by up to 10%.
