Through Hole Resistors

Through hole resistors are used in a variety of applications due to their small size, high accuracy, and durability. Through hole resistors are an electronic component designed to oppose the flow of current, creating a voltage drop between two points. They are made with a high-thermal conductivity material that resists heat and does not allow for current leakage. A good example of a through hole resistor is the H4249RBDA family.

H4249RBDA Application Field and Working Principle

The H4249RBDA family is known for its high accuracy and stability. They are made with a precision resistor molding process that tightly controls the resistance accuracy. This high precision also allows for very low power consumption and long life expectancy. The H4249RBDA family is used for various commercial and industrial purposes, such as power supplies, instrumentation, and measurement and control systems.

The H4249RBDA family of resistors works on the principle of Ohm’s law, where electrical current is proportional to voltage. When a voltage is applied to a resistor, a proportionate amount of current will flow through it, resulting in a voltage drop across the resistor. This voltage drop is inversely proportional to the resistance value of the resistor. The higher the resistance value, the lower the voltage drop across the resistor.

The H4249RBDA family of resistors use a metal film construction to achieve their high accuracy and stability. This is because metal film resistors have a very thin film of metal laid down on a substrate, which makes them highly accurate and stable. Metal film resistors have a smaller resistance temperature coefficient than carbon resistors, meaning they are less affected by temperature changes. This makes them ideal for applications where accuracy and stability are critical, such as measurement and control systems.

The H4249RBDA family has a high power tolerance up to 5W. This makes them ideal for use in applications where high power is required, such as power supplies and instrumentation. The H4249RBDA family also has a wide range of resistance values, from 0.1Ω to 10kΩ, making them versatile for a variety of applications.

The H4249RBDA family is also known for its robust design, which makes them suitable for use in harsh environments. They are sealed in a glass-filled plastic package to protect them from moisture and other contaminants. The package also helps to dissipate heat, making them highly efficient and reliable.

In conclusion, the H4249RBDA family of through-hole resistors is a highly accurate and reliable component. They are suitable for a wide variety of applications, from power supplies to instrumentation and measurement and control systems. Their welding construction and robust design make them suitable for harsh environments. With their high power tolerance and wide range of resistance values, the H4249RBDA family is the ideal choice for electronic solutions that require accuracy and stability.
