<p>The H490R9BCA is a type of through hole resistor which is widely used for a variety of electrical applications. It is a three-terminal resistor with a maximum power rating of 500mW and a tolerance of ±2%. The component features a low thermal coefficient and is made of materials which allow for good thermal cycling performance. It is available in various resistance values ranging from 2.2 ohms to 4.7 megaohms, making it suitable for a variety of applications.</p><p>The resistor is commonly used in circuits that require a stable voltage reference over a wide operating temperature range, such as in automotive and audio circuits. Its low thermal coefficient and stability make it an ideal choice for high-accuracy, high-stability applications. Additionally, the component is used in low-noise and low-ripple amplifier circuits, as well as in power supplies and controllers.</p><p>The H490R9BCA features both an internal and external temperature coefficient. The internal coefficient is defined by the resistor’s electrical resistance and the external coefficient is determined by the ambient temperature. The component is designed to operate within a temperature range of -65°C to +125°C, making it suitable for use in a variety of industrial and commercial applications.</p><p>The resistor is constructed with two terminals to allow for easy connection to other components and devices. The center terminal is connected to a heat sink or heat spreader, while the outer terminals are each connected to a power source. The resistor’s thermal characteristics prevent it from becoming too hot by dissipating heat away from the board.</p><p>The working principle of the H490R9BCA is based on the Ohm’s Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points, provided there is no heat buildup. In the case of the H490R9BCA, the current is limited by the resistor’s thermally defined resistance, which is determined by the ambient temperature. The resistor therefore acts as an electrical voltage regulator by limiting the current passing through it to a safe level.</p><p>In conclusion, the H490R9BCA is a three-terminal, through hole resistor which is widely used for a variety of electrical applications. The resistor is typically used in applications which require a stable voltage reference over a wide operating temperature range and can also be used in low-noise and low-ripple amplifier circuits, as well as in power supplies and controllers. The resistor works on the basis of Ohm’s Law and limits the current passing through it to a safe level, allowing it to act as an electrical voltage regulator.</p></pre>
