This document introduces the features of ERA2A, 3A, 6A, 8A series metal film chip resistors, including high reliability, high accuracy, high performance, etc.
The ERA series includes 0402, 0603, 0805 and 1206 chip resistors with power ratings from 0.063 W to 0.25 W, TCR of +10 ppm/°C, and tolerance around ±10 %. They meet IEC 60115‑8, JIS C 5201‑8 and EIAJ RC‑2133A standards and are supplied in punched‑carrier or taped reels.
Safety and handling guidelines cover recommended soldering (preheat 140‑160 °C for 60‑120 s, peak up to 235 °C for ≤10 s), storage (5 °C‑35 °C, 45‑85 % RH), and precautions against moisture, static, and excessive mechanical stress. Packaging markings include part number, quantity and country of origin.
