ACASA1503B1503P100

ACASA1503B1503P100 Description

The ACASA1503B1503P100 from Vishay is a high-precision thin-film resistor array designed for demanding electronic applications. This 4-resistor network features 150KΩ/150KΩ resistance values with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a conformal-coated 1206 (4 x 0603) package, it offers 0.3W total power dissipation (0.1W per resistor) and a 75V maximum voltage rating. The 8-pin convex termination and surface-mount design make it ideal for compact PCB layouts. Compliant with EU RoHS (with exemption) and classified under ECCN EAR99, it is suitable for industrial and commercial use.

ACASA1503B1503P100 Features

• Precision Thin Film Technology: Delivers high accuracy (±0.5%) and low TCR (±25ppm/°C) for stable operation in varying environments.
• Isolated Circuit Design (ISOL): Ensures minimal crosstalk between resistors, critical for signal integrity.
• Compact 1206 (4 x 0603) Package: Saves board space while providing four independent resistors.
• Conformal Coating: Enhances durability against moisture and contaminants.
• High Power Handling: 0.3W total (0.1W per resistor) with derating up to 125°C.
• Automated Assembly Friendly: Supplied in tape and reel (T/R) for efficient SMD placement.
