CRB3A4E111JT

CRB3A4E111JT Description

The CRB3A4E111JT is a high-performance surface-mount resistor network from KYOCERA AVX's CRB series, designed for precision circuit applications. This 4-resistor array features a compact 1206 (3216 Metric) concave package with long-side terminals, offering a 110Ω resistance per element at ±5% tolerance. With a ±250ppm/°C temperature coefficient and 62.5mW power rating per resistor, it ensures stable performance across varying thermal conditions. The isolated circuit design minimizes crosstalk, making it ideal for signal integrity-critical applications. Its 0.028" (0.70mm) low-profile height and 3.20mm x 1.60mm footprint enable high-density PCB layouts.

CRB3A4E111JT Features

• 4 isolated 110Ω resistors in a single 1206 package, reducing board space and assembly complexity.
• Concave, long-side terminal design enhances solder joint reliability and mechanical stability.
• ±250ppm/°C TCR ensures minimal resistance drift under thermal stress.
• 62.5mW power dissipation per element balances performance and thermal management.
• MSL 1 (Unlimited) moisture sensitivity allows extended storage without baking.
• RoHS-compliant and REACH-unaffected, meeting global environmental standards.
• Tape & Reel (TR) packaging for automated pick-and-place assembly efficiency.

CRB3A4E111JT Applications

This resistor array excels in:

• Voltage division and pull-up/down networks in digital circuits (e.g., microcontrollers, FPGAs).
• Signal conditioning for sensors, ADCs, and communication interfaces (I2C, SPI).
• Impedance matching in high-frequency RF and analog circuits.
• Consumer electronics, industrial controls, and automotive subsystems requiring compact, reliable passive networks.
• Obsolete but still viable for legacy designs or replacements in maintenance cycles.
