CRB3A4E680JT

CRB3A4E680JT Description

The CRB3A4E680JT is a 4-resistor surface-mount network from KYOCERA AVX's CRB series, designed for high-density PCB applications. This 1206 (3216 Metric) concave long-side terminal package features isolated 68Ω resistors with a ±5% tolerance and ±250ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. With a compact footprint of 3.20mm x 1.60mm and a low profile of 0.70mm, it optimizes board space while delivering 62.5mW power per element. The device is RoHS-compliant, REACH-unaffected, and rated MSL 1 (unlimited) for moisture sensitivity, making it suitable for extended storage and handling.

CRB3A4E680JT Features

• High-Density Integration: Four isolated 68Ω resistors in a single 1206 package reduce component count and simplify layout.
• Robust Performance: ±250ppm/°C TCR and ±5% tolerance ensure reliability in precision circuits.
• Space-Saving Design: Concave long-side terminals enhance solder joint integrity while maintaining a 0.028" (0.70mm) height.
• Industry-Standard Compatibility: Compatible with 1206 reflow processes and supplied in tape & reel (TR) for automated assembly.
• Environmental Resilience: EAR99/ECCN classification and REACH compliance support global deployment.

CRB3A4E680JT Applications

Ideal for signal conditioning, pull-up/pull-down networks, and voltage division in:

• Consumer Electronics: Smartphones, tablets, and wearables requiring compact, high-reliability components.
• Industrial Controls: PLCs and sensor interfaces where stable resistance under thermal stress is critical.
• Automotive Systems: Infotainment and ECU designs benefiting from its AEC-Q200-qualified series variants (though this specific model is obsolete).
• Telecom Infrastructure: RF modules and baseband PCBs leveraging its low-profile, high-density layout.

Conclusion of CRB3A4E680JT

While obsolete, the CRB3A4E680JT remains a benchmark for space-constrained, multi-resistor applications, offering Kyocera AVX's proven concave terminal design for mechanical stability. Its balance of precision, power handling, and miniaturization makes it a historical reference for engineers evaluating modern alternatives in the CRB series or comparable 1206 resistor networks. For legacy designs, it exemplifies the durability and efficiency expected from KYOCERA AVX's passive component portfolio.
