Compact, High power, High surge resistance ESR01 Series anti-surge chip resistors

Overview

With the progression of compact devices towards greater functionality and miniaturization comes an increasing need for smaller, higher power resistors. ROHM meets this need with 0.2W anti-surge chip resistors in the 1005 (0402in) size, developed utilizing ultra-compact fine process, printing, and technologies.

Package

Key Feature 1 : Compact, high power

 0.2W resistor in the 1005 (0402in) size

Features include 3.2 times the rated power of ROHM's conventional products (guaranteed 0.2W), making it possible to replace 1608 (0603in) size units, reducing mounting area by 60%.

Higher rated power

Key Feature 2 : Improved ESR resistance

The ESR01 Series utilizes an optimized resistive element pattern and material for superior surge characteristics and 2kV ESD resistance (HBM).
