Through Hole Resistors are essential components in many circuits. The H83K4BYA is a through-hole resistor specially designed for use in military, industrial and commercial applications. It has a high performance flat-top construction that provides superior heat dissipation and an electrical performance that is unmatched in the industry. The H83K4BYA is a military-specified resistor with an operating temperature range of -55C to +127C and an impedance range of 0.1 to 500 watts. It has a rated power rating of 25 watts and a power rating of 1/2 watt.

The H83K4BYA is a non-inductive, hermetically sealed, and moisture resistant resistor. It is relatively small in size with dimensions of 4.5mm (D) x 5.1mm (W) x 10.3 mm (H). Its design allows for higher current tolerance and greater power dissipation than the traditional through hole resistors. It also has a high transient endurance of 100s milliseconds at 350V and I2T of 4.25kVA.

The working principle of the H83K4BYA is based on the reverse leakage current of a diode. The diode has an internal resistance composed of two layers of varistor material. These layers act as a gate, allowing current to flow only in one direction. When voltage is applied to the positive side of the diode, a small current begins to flow through the resistor, producing a high resistance value. The resistance value is directly proportional to the applied voltage, thus maintaining the required current and voltage settings. The H83K4BYA resistor also has a pulse overload protection feature that limits the power of the resistor and protects it from damage.

The H83K4BYA is available in both the single coil and dual coil configurations. The single coil is ideal for low power applications and provides resistance values up to 12K Ohms in a single turn. The dual coil configuration is for higher power applications and provides values up to 28K Ohms in two turns. The device is also available in a variety of sizes, from 3mm to 12mm.

The H83K4BYA resistor is commonly used in military, industrial, heavy-duty, and telecom applications. It can be used in power supplies, limiters, regulators, motors, and power converters. It is also frequently used in automotive, instrumentation, medical, and audio applications. Due to its small size, the resistor can be easily integrated into compact designs. The device is highly reliable and has long-term stability and reliability ratings.

H83K4BYA resistors are designed for use in DC and AC applications. They are also used in circuits with low output voltages, such as sensors or detectors. The reverse leakage current of the device makes it ideal for use in high voltage applications, as it prevents spikes or overloads. With their high resistance, low noise, and low power capabilities, H83K4BYA resistors are considered to be among the most reliable and stable through hole resistors available.
