The H856KFYA through hole resistor is a rugged and reliable resistor designed for harsh environments and demanding applications. The H856KFYA is constructed with a cylindrical, nickel-plated steel case, with two solderable leads for connecting to a circuit board or other terminal. It is rated for up to 500 volts at 1000 watts, and comes in a variety of resistance values such as 0.5 ohm to 10 megohms. It also has a wide temperature range of -55 to +175 degrees Celsius.

This type of resistor is well suited for circuit board applications, such as replacing shorted components or making adjustments to gain settings. It is also suitable for high-voltage and high-current applications, such as in power supplies and motor control circuits. Its rugged construction makes it suitable for use in harsh environments that may be subject to shock and vibration.

The working principle of the H856KYFA is based on electrical resistance. When electricity passes through a resistor, some of the energy is converted to heat. This process is known as Ohm\'s law, which states that the voltage across a resistor is equal to the current that flows through it multiplied by its resistance. The resistance of the resistor determines how much current can pass through it, which results in a specific amount of power being dissipated as heat.

The H856KFYA uses a ceramic core, which has a low thermal coefficient and is able to withstand high temperatures. This type of resistor is able to dissipate more power than other resistors with a similar size due to its higher resistance value. The leads are insulated with a silicone rubber coating, which avoids an oxidation effect that can occur on certain metals.

The H856KYFA is also suitable for use in medical and safety applications due to its safety certification. It is UL1412 approved and meets the standards for IEC61010-1, which is a safety standard for low-voltage electrical devices.

In summary, H856KFYA through hole resistors are rugged and reliable components suitable for a range of applications, from circuit boards to power supplies and motor control circuits. Their wide temperature range and safety certifications make them a good choice for high-voltage and high-current applications. Their design ensures a high resistance value with good thermal and electrical characteristics, making them a reliable and cost-effective solution.
