Through Hole Resistors are one of the most common and widely used electronic components. The 93J40R is an example of such a resistor and is used in a variety of applications. This article will discuss the application field and working principle of the 93J40R.

The 93J40R is a through-hole metal-oxides-film resistor which is widely used in the production of printed circuit boards (PCBs). It is a type of non-inductive resistor and has an extended operating temperature range of -55°C to +150°C. This makes the 93J40R suitable for use in a variety of applications which require high-temperature operation. Examples of such applications include automotive electronics, industrial automation, and telecommunication equipment.

The 93J40R provides excellent electrical properties and stability in a wide range of frequencies, from low to high. It is also known for its excellent tolerance of +/-0.5%. This makes it an ideal choice for applications which require precise current-limiting and voltage-regulating circuits.

The standard 93J40R resistor package consists of a 14-pin metal housing, two terminals, and a ceramic substrate. The metal housing provides a physical barrier between the resistor and the environment, protecting it from damage and wear. The two terminals are used to connect the resistor to a power source, allowing for current to flow through the resistor. The ceramic substrate sits between the terminals and provides electrical insulation between them, preventing any unwanted current leakage.

The 93J40R works on the principle of Ohm’s Law, which states that the current passing through a resistor is directly proportional to the voltage applied across it, provided the temperature remains constant. This means that when the voltage applied across the 93J40R is changed, the current passing through it will also change accordingly. The amount of current passing through the resistor depends on the resistance of the resistor itself, as the higher the resistance, the lower the amount of current passing through it.

The 93J40R is a highly reliable and robust resistor which is suitable for a variety of applications, from low to high power. Its extended operating temperature range and excellent electrical properties make it an ideal choice for applications which require precise current-limiting and voltage-regulating circuits, as well as for applications which require high-temperature operation. It is also used in the production of PCBs, as its two terminals and ceramic substrate provide excellent electrical insulation and protection from external sources of damage.
