DFNA4991DT1 is a wide-frequency, broad-band, high-stability resistor network or an array manufactured by Exxelia Technologies. It is designed for demanding applications in various fields such as aerospace, military and medical device technology.

It is a two-terminal device and features four essential elements: a chip resistor, a capacitor, an inductor and a low-noise element. The chip resistor is designed with low-temperature coefficient (LtC), which helps in compensating for the frequency-dependent load reactance of the load. The chip capacitor has a low-drift capacitor-to-resistor ratio, which is suitable for a wide frequency range. The inductor is designed with high-stability ferrite material, which helps improve thermal stability. The low-noise element provides wide-band high-frequency performance with low distortion.

The DFNA4991DT1 is designed to provide superior performance in a variety of applications. It is well-suited for AC/DC power converters, active filters, solid-state relays, digital and analog signal conditioning, and measurement systems. It also has applications in medical devices, such as cardiac pacemakers and glucose monitors, as well as aerospace and military equipment.

The DFNA4991DT1 is designed to operate in a wide frequency range, offering superior performance at low-to-medium-frequency applications. It features excellent high-frequency operation with low distortion, and its two-terminal design ensures low-voltage operation. Additionally, it has low-temperature coefficient performance, providing improved system stability and reliability.

The working principle of the DFNA4991DT1 is based on the use of the four essential elements. The chip resistor is used to compensate for frequency-dependent load reactance and the chip capacitor is designed with low-drift ratio, which makes it suitable for wide frequency range operations. The inductor is manufactured with high-stability ferrite material, which helps reduce temperature drift and improve thermal stability. Finally, the low-noise element provides wide-band performance with low distortion.

The DFNA4991DT1 is a two-terminal broad-band, high-stability resistor network or array designed for demanding applications. It offers wide-frequency and low-distortion performance, with excellent thermal stability and low-temperature coefficient performance. As such, it is well-suited for applications such as AC/DC power converters, active filters, solid-state relays, digital and analog signal conditioning, and measurement systems.
