Resistor Networks, Arrays

DFNA1003BT1 is a type of resistor array designed for enhanced performance and improved safety in a wide variety of applications. It is housed in a small and compact case and is suitable for automated assembly on the surface. This resistor array has the following characteristics:

• High resistance accuracy and stability
• High power ratings
• Low DC resistance, typically 10Ω – 100Ω.
• High-efficiency operation
• High insulation resistance
• Wide operating temperature range –40℃ to +125℃

The DFNA1003BT1 can be used for several applications, such as biasing, switching, and high-performance power management applications. Its typical applications include:

• DC/DC converters
• Mobile phone and PDA battery charger circuitry
• Wireless communications systems
• Battery management and protection circuits
• Automotive applications

The DFNA1003BT1 also has a very useful working principle. It employs multiple resistors in parallel to increase the current handling capability of the device, reducing power dissipation. This device also utilizes a special technique called "Divisible Current Balancing" to balance the output current of the device over the multiple resistors, providing highly accurate current measurements as needed. By using these two methods, the DFNA1003BT1 can achieve the highest efficiency for its applications.

In addition to the high-efficiency and low power dissipation advantages, the DFNA1003BT1 also features over-voltage protection. This provides an extra safety measure to increase the device’s reliability and longevity. All these features make the DFNA1003BT1 an ideal choice for applications where efficiency and reliability are both paramount.
