NRSNA4I4J820TRF Description

The NRSNA4I4J820TRF from NIC Components is a high-performance thick film resistor array designed for precision surface-mount applications. This 4-resistor isolated (ISOL) network features a compact 0804 (4 × 0402) molded package with a rectangular shape, offering a space-saving solution for densely populated PCBs. Each resistor in the array has a 82Ω resistance value with a 5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. The device is rated for 0.063W (1/16W) power dissipation per resistor and supports a maximum voltage rating of 25V. Packaged in tape and reel (T/R), it is optimized for automated assembly processes.

NRSNA4I4J820TRF Features

• Isolated Circuit Design (ISOL): Each resistor is electrically independent, providing flexibility in circuit design.
• Compact 0804 Package: Combines four 0402-sized resistors into a single 2mm × 1mm × 0.4mm footprint, ideal for miniaturized designs.
• Thick Film Technology: Delivers robust performance with low noise and high reliability in harsh environments.
• Convex Termination: Ensures excellent solderability and mechanical stability during reflow processes.
• Wide Temperature Range: Operates reliably from -55°C to +125°C, with derated power up to 125°C.
• Automotive-Grade Alternatives: While not automotive-qualified, its EU RoHS compliance (with exemption) makes it suitable for industrial and consumer electronics.

NRSNA4I4J820TRF Applications

This resistor array excels in applications requiring space efficiency and signal integrity, such as:

• Voltage Division & Pull-Up/Down Circuits: Isolated resistors prevent cross-talk in multi-channel systems.
• Consumer Electronics: Used in smartphones, tablets, and wearables due to its miniature size and low-profile (0.4mm height).
• Industrial Control Systems: Reliable performance in PLC modules, sensors, and power management circuits.
• Telecommunications: Ideal for RF modules and signal conditioning where consistent resistance values are critical.
