CRB3A4E181JT

CRB3A4E181JT Description

The CRB3A4E181JT from KYOCERA AVX is a high-performance 4-resistor array designed for precision surface-mount applications. Part of the CRB series, this device features isolated resistors with a 180Ω resistance per element, 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 designs. The array is supplied in Tape & Reel (TR) packaging, compatible with automated assembly processes, and carries an MSL 1 (Unlimited) moisture sensitivity rating for ease of handling.

CRB3A4E181JT Features

• 4 isolated resistors in a single 1206 footprint, reducing board space and simplifying layout.
• Concave, long-side terminal design enhances solder joint reliability and mechanical stability.
• Low TCR (±250ppm/°C) and ±5% tolerance ensure consistent performance in temperature-sensitive applications.
• 62.5mW power dissipation per element balances compact size with robust power handling.
• REACH Unaffected and EAR99 ECCN compliant, suitable for global export and environmentally conscious designs.
• Obsolete status may require alternative sourcing but remains viable for legacy or low-volume production.

CRB3A4E181JT Applications

This resistor array excels in precision analog circuits, voltage dividers, and signal conditioning where space efficiency and reliability are critical. Its isolated configuration makes it ideal for:

• Sensor interfaces (e.g., bridge circuits in pressure or temperature sensors).
• Consumer electronics, such as audio equipment and display drivers.
• Industrial control systems, including PLCs and instrumentation requiring stable resistance networks.
• Automotive electronics, where compact, high-reliability components are prioritized.

Conclusion of CRB3A4E181JT

The CRB3A4E181JT combines KYOCERA AVX's proven reliability with a space-saving design, offering engineers a dependable solution for densely packed PCBs. While marked as obsolete, its 1206 concave package and isolated 180Ω resistors remain advantageous for legacy designs or niche applications demanding tight tolerance and low thermal drift.
