CRB2A4E222JT

CRB2A4E222JT Description

The CRB2A4E222JT from KYOCERA AVX is a compact 4-resistor array designed for surface-mount applications, offering a 2.2kΩ resistance per element with a ±5% tolerance. Encased in an 0804 (2.00mm x 1.00mm) concave package with long-side terminals, this resistor network is optimized for high-density PCB designs. Its ±250ppm/°C temperature coefficient ensures stable performance across varying thermal conditions, while the 62.5mW power rating per element balances efficiency and reliability. The isolated circuit configuration allows independent resistor operation, enhancing design flexibility. Although marked as obsolete, it remains a viable choice for legacy or low-volume production due to its REACH compliance and unlimited MSL1 moisture sensitivity rating.

CRB2A4E222JT Features

• Compact Footprint: 0804 package (2.00mm x 1.00mm) with a low profile (0.50mm height) for space-constrained designs.
• Stable Performance: ±250ppm/°C TCR and ±5% tolerance ensure consistent operation in industrial environments.
• High Reliability: Concave, long-side terminal design improves solder joint integrity and mechanical stability.
• Flexible Configuration: Isolated resistors enable versatile circuit topologies without cross-talk.
• Compliance: EAR99 and REACH Unaffected status simplifies global sourcing and integration.

CRB2A4E222JT Applications

This resistor array excels in:

• Signal Conditioning: Precision voltage division in sensor interfaces or ADC circuits.
• Pull-Up/Down Networks: Ensuring stable logic levels in microcontroller or FPGA-based systems.
• Consumer Electronics: Space-saving solution for wearables, IoT devices, and compact PCBs.
• Legacy Systems: Maintenance or repair of older equipment requiring obsolete component replacements.

Conclusion of CRB2A4E222JT

The CRB2A4E222JT combines miniaturization, reliability, and design flexibility, making it a pragmatic choice for applications demanding compact resistor networks with moderate precision. While obsolete, its robust construction and industry-standard performance ensure continued utility in niche or legacy projects. Engineers should evaluate alternatives for high-volume production but can leverage this model for prototyping or low-complexity circuits where space and stability are critical.
