ACASA100321003P100 Description

The ACASA100321003P100 from Vishay is a high-precision thin-film resistor array designed for demanding surface-mount applications. This 4-resistor isolated network features matched 100KΩ/100KΩ resistances with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Encased in a conformal-coated 1206 (4×0603) package, it offers 0.3W total power dissipation (0.1W per resistor) and a 75V maximum voltage rating, making it suitable for precision analog and digital circuits. The convex termination style enhances solder joint reliability, while the tape-and-reel packaging enables efficient automated assembly.

ACASA100321003P100 Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±50ppm/°C) for stable signal conditioning.
• Isolated Circuit Design (ISOL): Each resistor is electrically independent, ideal for multi-channel isolation.
• Robust Construction: Conformal coating enhances moisture and contaminant resistance in harsh environments.
• Space-Saving 1206 (4×0603) Footprint: Combines four 0603-sized resistors in a compact 3.2mm × 1.5mm × 0.45mm profile.
• Automation-Ready: Supplied in tape-and-reel for high-speed pick-and-place assembly.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
