ACASA100321003P500 Description

The ACASA100321003P500 from Vishay is a high-precision thin-film resistor array designed for demanding electronic applications. This 4-resistor network features 100KΩ/100KΩ resistance values with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Packaged in a 1206 (4 × 0603) conformal-coated case, 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 (SMD) design make it ideal for automated assembly, supplied in tape and reel (T/R) packaging for efficient production.

ACASA100321003P500 Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and stability (±50ppm/°C) for critical circuits.
• Isolated (ISOL) Configuration: Each resistor operates independently, reducing crosstalk in sensitive applications.
• Robust Construction: Conformal coating enhances durability in harsh environments.
• Compact Footprint: 1206 case size (3.2mm × 1.5mm × 0.45mm) with 0603 elements maximizes PCB space efficiency.
• Automation-Ready: Convex termination and tape-and-reel packaging streamline high-volume manufacturing.
• Compliance: EU RoHS compliant (with exemption) and EAR99 classified for global use.
