CRB2A4E272JT

CRB2A4E272JT Description

The CRB2A4E272JT from KYOCERA AVX is a compact, surface-mount resistor network designed for high-density PCB applications. This obsolete but reliable component belongs to the CRB series, featuring four isolated 2.7kΩ resistors with a ±5% tolerance and a ±250ppm/°C temperature coefficient. Encased in an 0804 concave package with long-side terminals, it offers a 62.5mW power rating per element and operates within a 0.020" (0.50mm) max seated height profile, making it ideal for space-constrained designs. The Tape & Reel (TR) packaging ensures compatibility with automated assembly processes.

CRB2A4E272JT Features

• Compact Footprint: Measures 2.00mm x 1.00mm (0804), enabling high-density layouts.
• Stable Performance: ±250ppm/°C TCR ensures minimal resistance drift across temperature variations.
• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, providing design flexibility.
• Automation-Friendly: MSL 1 (Unlimited) moisture sensitivity and TR packaging streamline mass production.
• Robust Construction: Concave, long-side terminal design enhances mechanical stability and solder joint reliability.

CRB2A4E272JT Applications

This resistor array excels in precision analog and digital circuits, including:

• Signal Conditioning: Voltage division and pull-up/down networks in sensor interfaces.
• Consumer Electronics: Space-saving solutions for smartphones, wearables, and IoT devices.
• Industrial Controls: Robust performance in PLCs and motor drivers.
• Medical Devices: Reliable operation in low-power diagnostic equipment.
  Its obsolete status may limit new designs, but it remains a cost-effective choice for legacy systems or inventory-based production.

Conclusion of CRB2A4E272JT

The CRB2A4E272JT balances miniaturization and performance, offering high reliability in a compact form factor. While newer alternatives may exist, its proven stability, isolation, and power handling make it a pragmatic choice for refurbishment or niche applications. Engineers should verify availability but can leverage its REACH compliance and Kyocera AVX’s quality legacy for enduring designs.
