The document describes the features and characteristics of MCR25 (3225 size: 1 / 4W) resistors, including the use of the same material as general purpose chip resistors, superior resistance to the elements with ruthenium oxide resistive material, and electrodes not corroded by soldering. The resistors are ISO-9001 certified and detailed information on dimensions and electrical characteristics is provided.
The document describes the ROHM MCR25 series of thick film rectangular resistors, which are made from the same material as general-purpose chip resistors (MCR10/18). They utilize ruthenium oxide resistive material for high reliability and resistance to environmental elements. The resistors feature electrodes that are not corroded by soldering, allowing for both flow and reflow soldering processes. This manual is written in Chinese.
| Resistive Material | Ruthenium oxide |
|---|---|
| Soldering Compatibility | Flow and reflow |
