Through Hole Resistors is a kind of electrical component widely used in various electronic applications, and H41K5BDA is a standard type of Through Hole Resistor with a unique set of properties. This article examines the application field and working principle of H41K5BDA.

Properties of H41K5BDA

The H41K5BDA Through Hole Resistor has a voltage rating of 250 Volts AC, a power rating of 1/4 Watt, and can operate under the temperature range of -55 to +125 Celsius. It is available in a package size of 6.3 x 3.5 mm and has a tolerance of ±10%, ±20%, ±5%, or ±1%. The H41K5BDA is constructed of two layers of resistive material which are bonded together and encased in high temperature anodized aluminum. Additionally, it has a very low self-inductance and a low dissipation factor.

Application Fields

The H41K5BDA Through Hole Resistor is highly suitable for use in a range of medium-voltage applications. Its high temperature anodized aluminum casing makes it ideal for use in high-vibration environments, as it is capable of withstanding extreme temperatures and vibrations without any loss in performance. It can also be used in switch mode power supplies, inverters, and controllers. Due to its low self-inductance and dissipation factor, it has low power dissipation and can be used in applications where low power dissipation is essential.

In addition to demanding applications, the H41K5BDA is suitable for use in more commonplace applications such as audio devices, amplifiers, oscillators, radios, and power supplies. The small package size and low profile make it ideal for use in tight spaces, such as in the case of hand-held electronics.

Working Principle

The H41K5BDA Through Hole Resistor works on the principle of creating a known resistance between two terminals. This resistance is created by the combination of two layers of resistive material, which are in contact with each other. The resistive layers are then encased in a package made of high temperature anodized aluminum, which helps to keep the temperature of the resistors consistent and reduces the risk of damage due to vibration or other external influences. The resistive value of the H41K5BDA is achieved by varying the thickness of the resistive materials and the spacing between them.

When voltage is applied to either of the two terminals of the H41K5BDA, a current is forced to flow through the resistor. The current is then limited due to the particular resistance of the resistor, and the voltage is diverted due to the presence of the resistor. This allows the H41K5BDA to act as an adjustable voltage divider, allowing the voltage of the circuit to be adjusted or limited. The H41K5BDA can also be used to reduce surges or to provide a predetermined current level.

Conclusion

The H41K5BDA Through Hole Resistor is a versatile electrical component that is ideal for a range of medium-voltage applications. Its unique two-layer resistive construction, combined with its robust anodized aluminum casing, make it suitable for use in high-vibration and high-temperature environments. Additionally, its small package size and low profile make it suitable for use in tight spaces. It can be used to regulate current, limit voltage, or as a voltage divider, and can be used in a range of applications including audio devices, amplifiers, oscillators, radios power supplies, switch mode power supplies, inverters, and controllers.
