Through hole resistors have been the go-to choice for power, control, and precision applications in industrial, automotive, and consumer markets for decades. Despite the rise of surface mount technology, through-hole resistors offer unparalleled customization and packaging options when compared to their surface-mount counterparts, making them ideal for high-power applications and certain types of control systems and circuits

The H840K2FDA is a series of through-hole power-type resistors manufactured by the well-known French company “Heabriest”. The series is composed of five models with six power ratings ranging from 0.277 watts to 2.5 watts. The resistors feature very low temperatures and highly stable temperature characteristics due to their precise design. The H840K2FDA series has the ability to handle a wide temperature range – from -55°C up to +125°C – making it suitable for extreme applications.

The H840K2FDA series offers unparalleled customization due to its wide range of wattage ratings and its use of multiple materials in its construction. The resistors are constructed of high-grade material such as ceramic, copper, aluminum, and nickel-plated steel, which contribute to its high performance and reliability. The series also feature permanent solder-connection points which provide robust mechanical strength, as well as a lower thermal resistance.

The H840K2FDA series is ideal for general purpose use, such as lighting, power supplies, and audio applications. The series is also suitable for use in medical instruments, high current applications, HVAC systems, and industrial motor controllers. The resistors are capable of withstanding high voltage pulses and can be used in high-reliability and high-precision applications. The H840K2FDA series is also one of the most reliable and versatile through-hole power resistors on the market.

The H840K2FDA series is designed with a self-heating principle. As current passes through the resistor, the resistive material heats up and increases its resistance, thereby limiting the current flowing through the resistor. This principle ensures that the resistor works continually to achieve the desired power level and will not be damaged due to an overload of current. The self-heating principle is also beneficial in applications where an exact amount of current is needed, as the resistor can ensure it is achieved.

The H840K2FDA series is designed with an axial lead design, which helps to ensure that the resistor’s leads don\'t move as a result of vibration. The series also features a one-piece ceramic case, providing additional protection from physical shocks and vibration, as well as dispersion of thermal energy. The series also boasts an overall pressure rating of IP50, making it suitable for use in dusty environments and other applications where it is necessary to protect the resistor from external elements.

By utilizing the self-heating principle, the H840K2FDA series is perfect for applications where extremely precise power levels are needed, as well as applications which require reliable and durable components. The series is also designed to be highly resistant to vibration and mechanical shocks, giving it superior performance in demanding settings. In addition, the series features an axial lead design which prevents its leads from moving due to vibration or other external factors, ensuring long-term reliability. The H840K2FDA series is an ideal choice for harsh and demanding applications, as it offers unparalleled performance in extreme environments.
