Product Overview
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.

Precautions for Use
- Ionic impurities such as flux, perspiration, or salt can negatively affect moisture and corrosion resistance. Washing is recommended, especially when using lead-free solder. Use of RMA solder or RMA flux and thorough washing is advised.
- Contact sales representatives before using products in applications including automotive, medical equipment, and aerospace equipment, as malfunction or failure could cause loss of human life or serious damage.
