In the world of electronics, Through Hole Resistors play a key role as standard, carbon film resistors. A Through Hole Resistor, such as the H473K2BYA, is used to decrease the signal level of circuits, block current flow in either direction, or alter the signal waveform. Depending on the frequency of a circuit, they can also be used to attenuate RF or control impedance. When applying a Through Hole Resistor, care must be taken to consider the size, value, power rating and temperature coefficient to ensure its correct use.

The H473K2BYA is a Through Hole Resistor with a 4K2 (4,200 Ohm) resistance value. It is a 4-band resistor color code body with a tolerance of ±5%. It is designed to function in both transverse and axial lead applications, providing a larger and flatter mounting surface. It is RoHS Compliant, and conforms to the EIA-JIS Standard. Additionally, the H473K2BYA has a power rating of 250mW and a temperature coefficient of ±200 ppm/°C.

The Through Hole design makes use of two leads, each coming out of the sides of the octagonal-shaped base. Its copper leads offer improved heat dissipation and higher power tolerance, making it suitable for more demanding applications. The body is made from an special epoxy coating, and includes standard color bands in order to ensure that the resistor’s resistance value is easily determined and read. The four colors, with each signifying a different number, can be decoded by its accompanying color code chart.

In many circuits, the main purpose of a Through Hole Resistor is to limit the current flow. Its resistance value is inversely proportional to the amount of current it can carry, meaning that a higher resistance resistor will be able to handle less current than a lower resistance resistor. It is important to note that the power rating plays a significant role in this, as the resistor must be able to dissipate a certain amount of energy without becoming damaged. The temperature coefficient also plays a role, as higher temperatures can have an adverse effect on the resistor’s ability to remain stable.

The H473K2BYA, as a standard Through Hole Resistor, is suitable for a wide variety of uses in a number of electrical and electronic devices. As long as the voltage and current are kept within the specified limits, the H473K2BYA will provide reliable operation. Its size, power rating, resistance value, temperature coefficient, and standard color bands make it easy to use in a variety of designs.
