H4649RBZA Through Hole Resistors

Through hole resistors, such as the H4649RBZA, are a type of passive electronic components used to reduce electric current in circuits. Through hole resistors are mainly used in applications where a large number of electrical components are required to be contained in one circuit. The H4649RBZA is a through hole resistor that has been specifically designed for precision signal applications such as audio and low-power amplifiers.

Application Field

The H4649RBZA is primarily used in precision signal applications, such as audio and low-power amplifier circuits. It is also suitable for digital audio applications, as well as analog signal applications. The H4649RBZA is a low-noise precision resistor, meaning it offers improved signal-to-noise ratio in audio applications and better power efficiency in analog and digital signal processing applications. In addition, the H4649RBZA can be used in automotive, data communication, instrumentation, and medical equipment circuits.

Working Principle

The working principle of the H4649RBZA is based on the theory of resistance, which states that a voltage applied across a resistor will cause a corresponding current to flow through the resistor. The amount of current is determined by the amount of resistance offered by the resistor. The H4649RBZA has a precise resistance value of 4.49 kOhms. This resistance is highly accurate, meaning that a very accurate voltage level can be maintained across the resistor and a very accurate current can be passed through it. In addition, the H4649RBZA is designed to be able to handle a large amount of current in a stable manner. It is capable of withstanding up to 500 mA of continuous current and up to 1A of peak current. This makes it suitable for more demanding applications, such as power amplifiers. The H4649RBZA also offers superior temperature stability in comparison to conventional resistors. It is able to maintain its resistance value over a wide range of temperatures from -55°C to +125°C. This temperature stability ensures that the resistance value of the resistor remains accurate even in harsh environmental conditions.In addition, the H4649RBZA through hole resistor is RoHS compliant, meaning it meets the standards set forth by the Restriction of Hazardous Substances Directive. This means that the resistor is free from lead and other hazardous materials, making it more environmentally friendly.

Conclusion

The H4649RBZA through hole resistor is an ideal component for use in precision signal applications. It offers superior accuracy, stability, and temperature resistance over conventional resistors. In addition, it is RoHS compliant, making it environmentally friendly. These features make the H4649RBZA through hole resistor well suited for a variety of applications such as audio and low-power amplifiers, digital audio, automotive, data communication, instrumentation, and medical equipment.
