NRSNA4I2J390TRF

NRSNA4I2J390TRF Description

The NRSNA4I2J390TRF from NIC Components is a high-performance thick film resistor array designed for precision surface-mount applications. This 39 Ohm, 5% tolerance device features a ±250ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. Housed in a compact 0404(2 X 0402) molded package, it integrates two isolated resistors in a 4-pin convex termination configuration, making it ideal for space-constrained PCB designs. The 0.063W (1/16W) power rating per resistor and 25V maximum voltage rating cater to low-power signal conditioning and voltage division tasks. Packaged in tape and reel (T/R), it supports automated assembly processes.

NRSNA4I2J390TRF Features

• Isolated Resistor Array: Two 39 Ohm resistors with ISOL (isolated) circuit design, eliminating crosstalk.
• Robust Construction: Molded case ensures mechanical durability and moisture resistance.
• High-Temperature Stability: Operates reliably up to 125°C with derated power up to 70–125°C.
• Compact Footprint: 1mm (L) x 1mm (D) x 0.3mm (H) dimensions and 0.67mm terminal pitch save board space.
• Automation-Friendly: Convex termination style enhances solder joint reliability, while SMD packaging simplifies pick-and-place assembly.
• Compliance: EU RoHS compliant (with exemption) and EAR99 ECCN for global market suitability.
