Through Hole Resistors

Through hole resistors are passive components typically used to control electrical current in a circuit. They come in a variety of styles and sizes, from solid encapsulated resistors to wire wound power resistors. The H449K9BDA is one of these types of through-hole resistors.The H449K9BDA is a non-inductively wound resistor, with a built-in coil that provides additional damping in high voltage circuits. It is designed to absorb and balance out electrical surges so that the equipment is protected from damage. It is also robust and can resist high temperatures up to 180°C.The H449K9BDA is suitable for a wide range of applications, including AC and DC circuits, audio frequency and low impedance devices, high voltage equipment, and electro-mechanical devices. The resistor can handle a maximum of 55V and a maximum power of 0.25W. Its operating temperature range is between -55°C and +200°C. The H449K9BDA works using four basic principles. First, it uses electrical resistance to regulate the current flowing through the circuit. Second, it uses electrical capacitance to store energy and regulate voltage within the circuit. Third, it uses thermal resistance to dissipate or absorb excess heat in the circuit. Finally, it uses thermal mass to absorb or dissipate heat in its surrounding environment. The H449K9BDA is a valuable component in many circuits, as it can help regulate electrical current, store energy, dissipate heat, and mitigate shock or vibration. This makes the resistor ideal for a variety of applications, including the automotive, industrial, military, and consumer electronics industries. In terms of construction, the H449K9BDA is made up of a non-inductively wound resistor and a coil, which is made from a material such as copper. The two components are then encased in an epoxy resin casting, which increases the resistor’s mechanical strength and insulation properties. This allows the resistor to be used in high-voltage applications, where some components may not be suitable.The H449K9BDA is a versatile and reliable through-hole resistor. It is suitable for a variety of applications, from AC and DC circuits to audio frequency and low impedance devices, and can handle a maximum of 55V and up to 0.25W power. Furthermore, it has a robust design and can withstand temperatures up to 200°C, making it a valuable component in many circuits.
