H420KBYA

H420KBYA resistors are widely used in a variety of electronic circuits for limiting the amount of current flow in a specific circuit, by providing a specific resistance to the circuit. These resistors are particularly useful in circuit designs where the designer may require a resistor with tight tolerance, high stability, and superior quality.

H420KBYA resistors are ballast type resistors with through hole mounting that can be securely installed on appropriate printed circuit boards (PCBs). It has excellent temperature characteristics and stability over long periods of time. It is a highly reliable, low cost, simple part that often functions without any external support, although it may need simple packaging like a heat sink or mounting frame for satisfactory performance under tough conditions. It is also an ideal choice for high-frequency applications.

Normally, the resistors used in electronic circuits come in various shapes and sizes with different mounting holes and lead lengths. H420KBYA resistors use a particular design called ‘through-hole’ type, where two or more leads are connected to the top of the resistor and go through a pre-drilled hole in the PCB board. This type of resistor offers excellent mechanical strength for secure mounting and highly reliable electrical connections.

The resistance value of H420KBYA resistors is typically offered as a range that is available in Ω, kΩ, and MΩ with tolerances ranging from ±5%, ±10%, ±20%. It also features a high power rating of up to 75 watts and excellent temperature coefficient, making it easy to use for a variety of applications.

When in use, H420KBYA resistors works by producing a specific current in response to the voltage applied across its lead terminals. The maximum current that can safely be applied to this type of resistor is determined by its power rating. The power rating of this type of resistor is expressed in terms of voltage and temperature, and the higher the voltage and temperature, the lower the power rating. The resistance value of this type of resistor will remain nearly constant over a range of temperature and voltage, making them extremely stable, even with high-frequency signals and large variation in signal levels.

H420KBYA resistors can be used for a variety of applications, including power supplies, switching regulators, motor control circuits, voltage references, light dimming, and heaters. These resistors are also suitable for telecommunications, automotive, and audio applications due to their excellent thermal and electrical properties.

The H420KBYA resistor is an incredibly versatile and reliable component, offering superior performance and reliability for a variety of different electronic applications. This type of resistor has been widely used in the electronics industry for decades, and its popularity continues to grow due to the wide range of advantages that it offers.
