Resistor networks, also known as resistor arrays, exist with a single common goal: to reliably provide precise resistance values to circuits without consuming all of the available space on a board. The Y4942V0403AT0L resistor network is an excellent example of this, as it provides four individual resistors (known as the terminals) with a specific resistance value of 400 Ohms (Ω) each. The last terminal is the common connection, which all four resistors share and is used as an electrical contact point with the device.

Design and Construction

The Y4942V0403AT0L resistor network is a glass-sealed device containing four individual resistors, each of which has been carefully selected to offer the same resistance of 400 Ohms (Ω). The most common packages are available in the standard SOT-23, which is 3 pins long. However, the device can also be found in packages with up to 8 pins, depending on the manufacturer.

The resistors in the Y4942V0403AT0L are each made from a tiny carbon chip and a non-conductive substrate, allowing for greater flexibility and customizability. The device is welded together using gold wire bonds, then it is encapsulated in a ceramic-glass material called a "blocker". Finally, the device is coated in an epoxy resin and cured to provide an extra layer of insulation against environmental damage.

Working Principle

The Y4942V0403AT0L resistor network works on the same basic principle as any other resistor array, albeit with more intricate details. This particular device requires a current to be passed through its leads, which is then divided equally amongst the four resistors in the array. The current then runs through each of the resistors and then returns to its source through the common lead.

Due to its specific resistance of 400 Ω, the Y4942V0403AT0L resistor network can be used in multiple applications, such as voltage dividers, power dividers, and divider circuits. In these applications, it allows for an even distribution of current or voltage, making it ideal for use in precision applications.

Applications

The Y4942V0403AT0L resistor network offers several benefits that make it an ideal choice for use in many applications. For starters, its SOT-23 package makes it easier to install due to its slim design. Additionally, the device\'s precise resistance of 400 Ω makes it ideal for voltage and power distribution applications where accuracy is key.

The Y4942V0403AT0L resistor network is also highly reliable and rugged, making it appropriate for use with industrial and commercial circuits, as well as automotive and aircraft systems. Additionally, its epoxy-coated construction provides extra protection against moisture and dust, allowing it to be used in situations where these environmental factors might otherwise be a concern.

Conclusion

The Y4942V0403AT0L resistor network is a great device for those seeking a reliable, rugged, and precise resistor array. Its SOT-23 package allows for easier installation, while its resistance of 400 Ohms makes it ideal for voltage and current division applications. Additionally, its epoxy-coated construction adds an extra layer of protection against environmental conditions. As such, the Y4942V0403AT0L resistor network is an excellent choice for any circuit in need of a reliable, space-saving, precision resistor array.
