BCN164A820J7 Description

The BCN164A820J7 from TT Electronics/IRC is a high-performance thick film resistor array designed for precision circuit isolation and signal conditioning. This 4-resistor network features an 82Ω resistance per element with a 5% tolerance and ±200ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -55°C to +155°C. Packaged in a compact 1206 (4×0603) SMD footprint, it offers a 0.25W (1/4W) total power rating (0.063W per resistor) and a 50V maximum voltage rating, making it suitable for dense PCB layouts. The isolated (ISOL) circuit design and 8-pin convex termination enhance reliability in high-vibration environments. Compliant with RoHS (with exemption) and supplied in tape-and-reel packaging, it is optimized for automated assembly.

BCN164A820J7 Features

• High-Density Integration: Combines four 0603-sized resistors in a single 1206 package, saving board space.
• Robust Construction: Thick film technology ensures durability and consistent performance under thermal stress.
• Wide Operating Range: Rated for -55°C to +155°C, with derated power up to 155°C.
• Low TCR: ±200ppm/°C minimizes resistance drift in temperature-sensitive applications.
• Automation-Ready: Convex-terminated SMD design and tape-and-reel packaging streamline pick-and-place processes.
