ACASA200122001P100 Description

The ACASA200122001P100 is a high-precision, conformal-coated thin-film resistor array manufactured by Vishay, designed for demanding surface-mount applications. This 4-resistor network features isolated (ISOL) circuit configuration with matched 2KΩ/2KΩ resistance values, offering tight tolerance (±0.5%) and low temperature coefficient (±50ppm/°C). Encased in a 1206 (4 × 0603) package, it delivers a 0.3W total power rating (0.1W per resistor) with a 75V maximum voltage rating, ensuring reliability in compact, high-density PCB designs. The conformal coating enhances environmental resistance, making it suitable for harsh operating conditions (up to 125°C). Packaged in tape and reel (T/R), it is optimized for automated assembly.

ACASA200122001P100 Features

• Precision Performance: Thin-film technology ensures ±0.5% tolerance and ±50ppm/°C TCR for stable operation in temperature-varying environments.
• Robust Construction: Conformal-coated 1206 (4 × 0603) rectangular package with convex terminations improves solderability and mechanical durability.
• High Power Handling: 0.3W total power dissipation (0.1W per resistor) at 70–125°C derated range, outperforming standard arrays in thermal management.
• Isolated Design: ISOL circuit configuration eliminates crosstalk, ideal for precision signal conditioning and voltage division.
• Automation-Ready: Tape and reel packaging streamlines high-volume SMD assembly.
