Through Hole Resistors

H4P464KDCA application field and working principle

Through hole resistors are one of the most commonly used components of electrical engineering. They come in a variety of shapes, sizes and capacities. H4P464KDCA is an example of a through hole resistor and it is mostly used in power supply applications. It is also suitable for driving small load current.

H4P464KDCA resistors are typically constructed with an oxide-coated copper core and an insulated wire wound around it. The core provides electrical isolation between the conductive materials in each coil, while the insulation keeps the wires from shorting out. The resistive elements, or resistors, are then connected to each other internally, allowing them to be switched on or off depending on the voltage applied. This process is known as switching.

When the voltage being applied across the resistor exceeds the rated voltage tolerance, the resistance value increases. This increased resistance produces a voltage drop across the resistor, which limits the amount of current passing through the circuit. This is known as current limiting, and is the principal purpose of a resistor in a power supply circuit. This allows for a steady flow of current to pass through the circuit with minimal effect on the voltage.

In order to properly operate H4P464KDCA resisters, the correct voltage must be applied in order to obtain the desired resistance value. This is usually accomplished with a voltage regulator. Regulators use adjustable resistors and capacitors to control the amount of current being driven through the circuit. If the voltage is too high, the current will exceed the rated tolerance, and could damage the resistor.

H4P464KDCA resistors can also be used as safety devices, for example, in the circuit protection or over-voltage protection of the AC power supply. The resistors can be connected in series or parallel to reduce the over-voltage current before it affects other components in the device. This helps prevent any component damage or fatalities.

Overall, H4P464KDCA resistors are popular and reliable components that are used to protect circuits from damage and provide reliable current limiting, voltage regulation, and protection from overvoltage. These resistors can be used to regulate the flow of electricity in a wide range of devices and applications.
