H434KBZAThrough Hole Resistors

Through hole resistors come in a variety of different formats, each suited to particular application requirements. The H434KBZA is a general-purpose through hole resistor with a wide range of applications making it well-suited for both commercial and industrial projects. Here we explore the application fields and working principle of this resistor.

Application Fields of H434KBZA

The H434KBZA is a fully encapsulated, hermetically sealed resistor and is ideally suited for use in both commercial and military applications. It is rated to operate in an ambient temperature range between -55 to 150 degrees Celsius and can handle rapid temperature cycling from -55 to 150 degrees Celsius. This makes it particularly suited for automotive, avionics and spaceflight applications where reliability and temperature resistance are paramount.

Due to its robust construction and wide range of temperature resistance, the H434KBZA is well-suited for use in medical devices, power electronics and other equipment where temperatures might vary. It is also an ideal choice for precision instrumentation due to its excellent short-term and long-term stability.

The H434KBZA is also available in various casing sizes and resistance ratings, making it an ideal solution for both commercial and industrial applications. Its small size and wide range of resistance ratings makes it suitable for circuits where space is limited.

Working Principle of H434KBZA

H434KBZA through hole resistors are made using a capacitor material such as polycarbonate or polyester. This capacitor material is wrapped in an epoxy resin, which provides both insulation and temperature resistance. The capacitor material is then laser cut into concentric circles forming a resistor element.

The resistor element is then embedded in a single-piece, hermetically sealed epoxy-encased housing. This housing provides mechanical protection and also serves as a heat dissipation mechanism, allowing for the operation of the resistor over a wide temperature range. The resistor element is also embedded in a ceramic or metal alloy material for additional protection.

When an electric current passes through the resistor element, a voltage drop is created. This voltage drop depends on the resistance of the element and the amount of current passing through the resistor. This voltage drop is then dissipated in the form of heat, which is then dissipated by the single-piece, hermetically sealed housing.

Conclusion

The H434KBZA through hole resistor is ideally suited for commercial and industrial applications due to its robust construction and wide range of temperature resistance. Its single-piece, hermetically sealed housing makes it suitable for medical devices, precision instrumentation, power electronics and other equipment where temperatures might vary. It is also an ideal choice for circuits where space is limited, due to its small size and wide range of resistance ratings. Furthermore, its working principle relies on the passing of an electric current to create a voltage drop – which is then dissipated in the form of heat.
