Through Hole Resistors

H4154KBZA is widely used in various applications as a through-hole resistor. It is a four-terminal resistor with a small footprint and a wire-lead design. It is capable of providing a constant resistance even when the temperature is varied, thereby providing a stable current flow. The resistor is typically used to control the current flow in electronic circuits, and is ideal for use in power supplies.

Application Field

H4154KBZA through-hole resistors are used in a wide range of applications, from industrial control systems to consumer electronic products. It is especially suitable for use in applications that require high current carrying capacity, such as industrial motors, power supplies, current-limiting circuits, and voltage-regulating circuits. It is also suitable for use in consumer electronic products, such as television, VCR, and DVD players, as well as in automotive applications such as generators, motors, alternators, and regulators. Additionally, the H4154KBZA through-hole resistor is used to regulate the current flow in digital circuits by serving as a load in a series configuration.

Working Principle

H4154KBZA through-hole resistors are based on the principle of ohms law. When current passes through the resistor, it causes energy to be dissipated in the form of heat, according to the formula: I2R = P. This equation states that the resistance of the resistor determines the amount of power dissipated as heat. In H4154KBZA, the resistance is preset to its rated value, and when current passes through the resistor, the heat dissipated is equivalent to the power dissipated.

The resistor has a tolerance rating for the resistance, which may range from 25% to 5%. This means that the resistor may have a resistance that is up to 25% higher or 5% lower than its rated resistance. The tolerance rating ensures that the current flow through the resistor remains constant, and therefore the power dissipated also remains constant, regardless of the temperature variation.

The four terminals of the resistor are generally connected in series in order to increase the total resistance of the circuit. This increases the ability of the resistor to dissipate power, and provides more control over the current. In addition, the four terminals of the resistor can be used in parallel to reduce the total resistance of the circuit, thereby allowing higher current flow in the circuit.

Conclusion

H4154KBZA is a four-terminal resistor with a small footprint and a wire-lead design. It is widely used in a variety of applications, including industrial control systems and consumer electronics, thanks to its high current carrying capacity and excellent tolerance rating. The resistor is based on the principle of ohms law, whereby the resistance of the resistor determines the amount of power dissipated as heat. The resistor is used to regulate the current flow in digital circuits by serving as a load in a series configuration.
