CRB3A4E101JT

CRB3A4E101JT Description

The CRB3A4E101JT is a surface-mount resistor network from KYOCERA AVX's CRB series, designed for high-density PCB applications. This 4-resistor array features isolated 100Ω 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 of 0.70mm, making it suitable for space-constrained designs. Rated at 62.5mW per element, it balances power handling and miniaturization. The device is REACH and RoHS compliant, with an ECCN of EAR99, and is supplied in tape-and-reel packaging for automated assembly.

CRB3A4E101JT Features

• High Integration: Combines four 100Ω resistors in a single 1206 package, reducing board space and assembly complexity.
• Stable Performance: ±250ppm/°C temperature coefficient ensures reliability in thermal-variable environments.
