Through Hole Resistors

Through hole resistors are one of the most commonly used electronic components, used to limit or control current in various electronic circuits. The H8634RBZA (H8634RBZA) is one such resistor, functioning as an ohmic resistance element. It is rated for operation at a wide range of temperatures, between -40 and 135 °C, and its power dissipation rating of 250mW ensures it is suitable for most low to medium power circuity. The maximum voltage applied to the leads should not exceed 25V for optimal performance.

Application Field

The H8634RBZA is designed for use in general-purpose analog and digital circuits, and is particularly suitable for circuits which require reliable long-term performance in a variety of environmental conditions. It is ideal for use in AC- and DC-powered circuits, and may be safely used for low-power logic bistable and signal-conditioning applications. Its low maximum voltage rating makes it suitable for applications requiring input signals at low voltages.

The H8634RBZA is also suitable for use in industrial applications where precise control of the current flow is necessary, due to its low tolerance of just ±5%. It has a wide range of operating temperature, allowing it to be used in heavily regulated and highly dynamic environments, including those subjected to rapidly changing temperatures.

Working Principle

The H8634RBZA works by limiting the flow of electrical current through it, reducing the voltage in the circuit, and providing a constant voltage drop. This is achieved using the basic principles of Ohm\'s Law; the current through a resistor is directly proportional to the voltage drop across it. When the current reaches a certain predetermined level, the voltage drop across the resistor also becomes constant, essentially providing a constant voltage source.

The resistance of the H8634RBZA is determined by its geometry, which is fixed at the time of manufacture. This includes the length and diameter of the resistive element, as well as the material used for the substrate. All of these factors affect the resistive value of the H8634RBZA, and thus the current flow in the circuit.

The H8634RBZA is designed for use in both digital and analog circuits, allowing it to act as a voltage regulator, current limiter, and thermal overload protector. This robust design makes it suitable for a wide range of applications, from low-power logic circuits to precision medical devices.
