CRB2A4E223JT

CRB2A4E223JT Description

The CRB2A4E223JT from KYOCERA AVX is a compact, surface-mount resistor network designed for high-density PCB applications. This 4-resistor array features isolated 22kΩ resistors with a ±5% tolerance and a ±250ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Housed in an 0804 concave package (2.00mm x 1.00mm) with long-side terminals, it offers a low-profile height of 0.50mm, making it ideal for space-constrained designs. Rated at 62.5mW per element, this obsolete but reliable component is packaged in tape and reel (TR) for automated assembly. Compliant with REACH and EAR99, it suits industrial and consumer electronics where precision and miniaturization are critical.

• Compact Design: 0804 concave package (2.00mm x 1.00mm) with a seated height of 0.50mm.
• Stable Performance: ±5% tolerance and ±250ppm/°C temperature coefficient for consistent operation.
• High-Density Integration: 4 isolated 22kΩ resistors in a single package, reducing PCB footprint.
• Automation-Friendly: Tape and reel packaging (TR) for efficient pick-and-place assembly.
• Robust Compliance: REACH unaffected and ECCN EAR99 certified for global use.
• Low-Power Handling: 62.5mW power rating per resistor, suitable for signal conditioning circuits.

CRB2A4E223JT Applications

This resistor array excels in applications requiring precision and space efficiency, such as:

• Signal Termination & Pull-Up/Down Networks: Ensures stable logic levels in digital circuits (e.g., I2C, SPI).
• Voltage Dividers: Used in sensor interfaces or ADC reference circuits.
• Consumer Electronics: Ideal for smartphones, wearables, and IoT devices due to its miniaturized form.
• Industrial Controls: Reliable performance in PLCs and instrumentation where temperature fluctuations occur.

Conclusion of CRB2A4E223JT

The CRB2A4E223JT balances compactness, precision, and reliability, making it a pragmatic choice for modern electronics despite its obsolete status. Its 0804 concave package and isolated resistors simplify layout while meeting stringent space and performance requirements. While newer alternatives exist, this Kyocera AVX array remains a cost-effective solution for legacy designs or applications where its specifications align perfectly. Engineers should evaluate replacement options for future-proofing but can leverage this model for proven, low-risk integration.
