Through hole resistors can be broadly classified into radial and axial components. The H497R6BZA is an example of the latter being designed to be soldered directly onto a PCB. It is a carbon film resistor with a power rating of 0.25 W and operating temperature range of -55°C to +125°C.

The H497R6BZA is mainly used when a low-profile, low cost, and reliable resistor is required. It can be used in a wide range of both low- and high-power applications. It is most commonly used as a shunt resistor for regulating unregulated supplies, or in circuit protection, such as overvoltage protection. They are also used in audio frequency amplifiers and other high frequency circuits, as well as in power supply circuits, where low power dissipation is important.

The H497R6BZA is a through-hole device, which is generally a more reliable than its surface mount counterparts, as it is less prone to vibration and thermo-mechanical shock. The resistor also features a high surge rating, allowing it to handle high inrush current without being damaged. This makes it an ideal choice for high voltage circuits and applications where the load is rapidly changed.

The H497R6BZA is driven by the principle of ohmic resistive heating. More specific ally, it is an ohmic device with a fixed resistance value across a wide range of temperatures and frequencies.When a voltage is applied across this resistance, current in proportion to the applied voltage is generated. This current is converted to heat in the resistive material, which results in a temperature rise. This temperature rise is used to regulate the current flowing through the resistor.

The resistor also features a tolerance level rating, indicating the accuracy of the resistance value. A tolerance value of ±5% indicates that the resistor may be up to 5% higher or lower than the specified resistance value. The Temperature Coefficient Of Resistance (TCR) specifies how the resistance of the resistor changes with temperature. The H497R6BZA has a TCR of ±100 ppm/K.

The H497R6BZA is a robust and reliable resistor and is well-suited for use in circuit designs where low-power dissipation, reliability and tolerance accuracy is essential. Its through-hole construction ensures that it can withstand vibration, shock, and even sudden changes in power supply.
