Through Hole Resistors

Through hole resistors are discrete components used in all kinds of electronic circuits. They contain one or two leads or legs riding through the center of the resistor that can be soldered to the circuit board. The H8619KDZA is a through hole resistor with its own unique application field and working principle.

Application Field

The H8619KDZA is a through hole resistor with high-temperature, oxide-film coated metal-alloy resistor. It is suitable for military and aerospace applications. It also features superior high temperature performance greater than 150 percent at rated power up to +175C and capable of continuous operation at +200C with no failure. Another advantage of this device is its low noise – it has the ability to provide uniform dissipation of heat without increasing thermal noise.

Working Principle

The working principle of the H8619KDZA is based on the resistive heating principle. It is the most commonly used form of electrical resistance heating. This resistor contains a coil of resistance wire or ribbon that is surrounded by an insulating material (ceramic, silica gel, or fiberglass). The resistive heatingwire is then passed through a heat source such as a transistor or a heater element to produce the necessary heat to complete the circuit.

When a voltage is applied across the resistor, electrons flow through the resistor’s coil and collide with the energy of the resistor, which causes it to heat up. The total resistance of the resistor is determined by the number of turns, the shape of the coil, the type of wire used, and the type of insulation. The resistance values and power dissipated by the resistor will depend on the type of wire and its insulation.

The heat produced by the resistor will depend on the current applied and the type of heat source. The temperature of the resistor will increase with increased current. The power of the resistor will also increase as the voltage is increased. Once the desired temperature is reached, the circuit will shut off to prevent over-heating.

The H8619KDZA is designed to provide sufficient thermal protection, so that it can be used in extreme temperatures without becoming damaged. It is capable of withstanding large temperature jumps over long periods of time with minimal thermal runaway. The only risk with using this resistor is that it can become overloaded with too much current. In such circumstances, the resistor may either start to overheat or be damaged beyond repair.

Conclusion

Overall, the H8619KDZA is an excellent through-hole resistor choice for use in military and aerospace applications. It is capable of withstanding high temperatures and large temperature jumps without suffering damage. Additionally, it features a low noise level, making it an ideal choice for low noise applications.
