CN1J4LTE103J Description

The CN1J4LTE103J by KOA Speer Electronics, Inc. is a high-performance thick film resistor array designed for automotive and industrial applications. This 4-resistor network features a 10KΩ resistance value per element with a 5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +155°C. Housed in a compact 1206 (4 x 0603) concave SMD package, it offers space-saving integration with an 8-pin termination style. The device is rated for 1/16W (0.063W) power dissipation per resistor and a maximum voltage rating of 50V, making it suitable for precision circuit designs requiring isolation (ISOL).

CN1J4LTE103J Features

• Automotive-Grade Reliability: Compliant with AEC-Q200 standards, ensuring durability in harsh environments.
• High-Density Design: Combines four 0603-sized resistors in a single 1206 footprint (3.2mm x 1.6mm x 0.6mm), optimizing PCB space.
• Robust Construction: Thick film technology provides excellent stability and low noise, ideal for signal conditioning and voltage division.
• Concave Termination: Enhances solder joint reliability, reducing mechanical stress during thermal cycling.
• Wide Temperature Range: Derated power operation from 70°C to 155°C supports high-temperature applications.
• Non-RoHS Compliant: Contains SVHC (Substances of Very High Concern), necessitating careful material management.
