This document is the datasheet of ROHM's UCR03 series of ultra-low power thick film resistors. This series of resistors has a resistance range of 20mΩ-910mΩ, 0.25W-0.2W rated power, and a working temperature range of -55°C-+155°C.
The UCR03 series are fixed thick‑film chip resistors designed for current detection with ultra‑low resistance values ranging from 20 mΩ to 910 mΩ. They feature superior rated power, stable low resistance across environments, and ISO‑9001/TS‑16949 certification.
The datasheet details electrical characteristics such as rated power (0.02 W – 0.2 W), operating temperature range (‑55 °C to +155 °C), tolerance (±1 %), and packaging options like paper‑tape reels. It also includes test conditions, solderability information, and usage notes for transient loads.
