ERA3YEB121V – PANASONIC

Overview

The Panasonic ERA-3YEB121V is a high-precision 120 Ohm metal film chip resistor designed for demanding surface-mount applications. Its defining characteristic is an exceptionally tight ±0.1% tolerance, crucial for maintaining signal integrity and accurate biasing in sensitive circuits. While its low 1/10W power rating is suitable for many signal path applications, designers must carefully consider thermal management to prevent drift and ensure long-term stability, as exceeding its dissipation limit can compromise its tight tolerance and overall performance.
