CRA04S0431K50JTD

CRA04S0431K50JTD Description

The CRA04S0431K50JTD is a compact, surface-mount resistor network from Vishay Dale's CRA04 series, designed for high-density PCB applications. This obsolete but still relevant model features two isolated 1.5kΩ resistors with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in a 0404 (1010 Metric) convex package, it measures just 1.00mm x 1.00mm with a seated height of 0.45mm, making it ideal for space-constrained designs. The array is RoHS3 compliant, has an MSL 1 (Unlimited) moisture sensitivity rating, and is supplied in tape & reel (TR) packaging for automated assembly.

CRA04S0431K50JTD Features

• Compact Footprint: Ultra-small 0404 package (1.00mm x 1.00mm) maximizes board space efficiency.
• High Reliability: ±200ppm/°C TCR and 62.5mW power rating per resistor ensure consistent operation under thermal stress.
• Isolated Circuit Design: Independent resistors reduce crosstalk, suitable for precision signal conditioning.
• Automation-Friendly: Tape & reel packaging streamlines high-volume PCB assembly.
• Compliance: ROHS3 and EAR99 certifications meet global environmental and export standards.

CRA04S0431K50JTD Applications

This resistor array excels in miniaturized electronics requiring precise voltage division or pull-up/down functions, such as:

• Portable Consumer Electronics: Smartphones, wearables, and IoT devices where space is critical.
• Medical Devices: Compact sensor interfaces and low-power diagnostic equipment.
• Industrial Controls: Signal isolation in PLCs and automation systems.
• Telecom Infrastructure: High-density PCBs for routers and baseband units.

Conclusion of CRA04S0431K50JTD

While marked obsolete, the CRA04S0431K50JTD remains a viable choice for legacy designs or applications demanding miniaturization, isolation, and stable performance. Its low-profile, high-reliability construction and compliance with modern standards make it a pragmatic solution for engineers tackling space-constrained, precision circuit challenges.
