CRB3A4E683JT

CRB3A4E683JT Description

The CRB3A4E683JT from KYOCERA AVX is a high-performance 4-resistor network designed for precision surface-mount applications. Part of the CRB series, this device features isolated 68kΩ resistors with a ±5% tolerance and a ±250ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in a compact 1206 (3216 Metric) concave package with long-side terminals, it offers a 62.5mW power rating per element and a low-profile 0.028" (0.70mm) seated height, making it ideal for space-constrained PCB designs. The Tape & Reel (TR) packaging and MSL 1 (Unlimited) rating facilitate efficient automated assembly processes.

CRB3A4E683JT Features

• 4 isolated 68kΩ resistors in a single 1206 footprint, reducing board space and assembly complexity.
• ±5% tolerance and ±250ppm/°C TCR for reliable performance in precision circuits.
• Concave, long-side terminal design enhances solder joint reliability and mechanical stability.
• 62.5mW power dissipation per resistor, suitable for low-power analog and digital applications.
• RoHS-compliant and REACH Unaffected, meeting global environmental standards.
• Obsolete status may require alternative sourcing for new designs, but remains viable for legacy systems.

CRB3A4E683JT Applications

This resistor network excels in:

• Voltage division and pull-up/down circuits in microcontrollers and sensors.
• Signal conditioning for industrial automation and instrumentation.
• Impedance matching in communication modules (e.g., IoT devices).
• Legacy electronics repair due to its standardized 1206 footprint.
• Automotive infotainment systems, where stable resistance values are critical.

Conclusion of CRB3A4E683JT

The CRB3A4E683JT combines KYOCERA AVX's reliability with a compact, high-density design, offering engineers a robust solution for isolated resistor networks. While marked as obsolete, its 1206 compatibility, low thermal drift, and ease of integration make it a pragmatic choice for maintenance or niche applications.
