CRB3A4E433JT

CRB3A4E433JT Description

The CRB3A4E433JT from KYOCERA AVX is a high-performance 4-resistor network in a compact 1206 (3216 Metric) surface-mount package. Designed for precision applications, it features 43kΩ resistance per element with a ±5% tolerance and a ±250ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The isolated circuit type allows independent resistor functionality, making it versatile for complex designs. With a 62.5mW power rating per element and a low-profile 0.028" (0.70mm) seated height, it is ideal for space-constrained PCBs. The concave, long-side terminal design enhances solder joint reliability, while the Tape & Reel (TR) packaging facilitates automated assembly.
