Through Hole Resistors are integral components of countless electronic applications and the NKN400JR-73-27R is no exception. The NKN400JR-73-27R is a through hole axial resistor with a tolerance of ±5% and a resistance of 400 ohms. It has a wattage rating of 1/8 Watt and is lead free.

The NKN400JR-73-27R resistor has a fairly narrow application field. Its wattage rating and resistance make it suitable primarily for digital or TTL (Transistor-Transistor-Logic) applications, and it is often used as a pull-up or pull-down resistor. Pull-up or pull-down resistors determine logic states in digital circuits, providing the resistance necessary to source or sink the current necessary for proper circuit operation. The NKN400JR-73-27R does this by establishing a balance between the voltage and current in a circuit.

The principle of operation of the NKN400JR-73-27R is simple. It works by providing a predetermined resistance in the circuit, which determines the voltage-current ratio. The current in the circuit is always equal to the applied voltage over the resistance of the resistor. This is dictated by Ohm’s Law, whereby the voltage (V) in a circuit is equal to the product of the current (I) and the resistance (R). This is mathematically represented as: V=IR.

The applied voltage of the NKN400JR-73-27R affects the amount of current that flows through it. If a higher voltage is applied to the resistor, more current will flow through it and the voltage-current ratio will be higher. If a lower voltage is applied, the current will be lower, and the voltage-current ratio will be lower. The main purpose of the NKN400JR-73-27R is to resist a given amount of electrical current while producing a known voltage drop.

The NKN400JR-73-27R is also frequently used as a current-limiting resistor, a voltage-divider resistor, or a constant-current resistor. As a current-limiting resistor, it prevents excessive current flow that could overload or damage the circuit in which it is used. As a voltage-divider resistor, it creates two voltages from an applied voltage such that the ratio of the two voltages is determined by the ratio of the resistor’s resistance values. Lastly, as a constant-current resistor, the NKN400JR-73-27R restricts the flow of current to whatever level is necessary for the particular circuit it is part of.

The NKN400JR-73-27R is a very versatile resistor which can be used in many applications. Its ability to regulate the current-voltage ratio, limit current flow, and divide voltages makes it a useful tool for many digital or TTL applications. As a through hole axial resistor, it is also easy to install and maintain.
