These general-purpose, lead-type carbon film resistors feature a CF Coat insulation and are designed for automatic insertion. They offer enhanced pulse resistance compared to chip resistors of equivalent power. Available in various forming types, including a smaller 1/4W size (CFS 1/4), these resistors meet EU-RoHS requirements and are manufactured to international standards including IEC 60115-2, JIS C 5201-2, and EIAJ RC-2136. They are suitable for a wide range of applications requiring reliable fixed resistance.
