CRB3A4E304JT

CRB3A4E304JT Description

The CRB3A4E304JT from KYOCERA AVX is a high-performance, surface-mount resistor network designed for precision applications. This 4-resistor array features isolated 300kΩ 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 footprint of 3.20mm x 1.60mm and a low-profile height of 0.70mm, making it ideal for space-constrained PCB designs. With a power rating of 62.5mW per element, this obsolete but reliable component is packaged in Tape & Reel (TR) for automated assembly efficiency.

CRB3A4E304JT Features

• 4 isolated resistors in a single 1206 package, reducing board space and assembly complexity.
• Concave, long-side terminal design enhances solder joint reliability and mechanical stability.
• Low-profile (0.70mm) suits high-density applications like wearables and IoT devices.
• ±250ppm/°C temperature coefficient ensures minimal resistance drift under thermal stress.
• REACH Unaffected and MSL 1 (Unlimited) compliance guarantees environmental and handling robustness.
• 62.5mW power rating per resistor balances performance with thermal management.

CRB3A4E304JT Applications

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

• Voltage dividers and pull-up/pull-down networks in microcontrollers and sensors.
• Signal conditioning for industrial automation and medical devices.
• Impedance matching in RF and communication modules.
• Consumer electronics, such as smart home systems, where board space optimization is critical.
  Its isolated circuit design prevents crosstalk, making it superior to bussed arrays in noise-sensitive applications.

Conclusion of CRB3A4E304JT

The CRB3A4E304JT combines Kyocera AVX’s reliability with a compact, high-density design, offering engineers a robust solution for precision resistor networks. While obsolete, its low thermal drift, isolated resistors, and concave package make it a preferred choice for legacy designs or replacements in space-sensitive, high-reliability systems. Ideal for industrial, medical, and consumer applications, it balances performance with manufacturability.
