Application Restrictions
High reliability applications are subject to contact with the manufacturer. Examples include aircraft equipment, aerospace equipment, power plant control equipment, medical equipment, transportation equipment, disaster prevention equipment, data processing equipment, and similar applications requiring high reliability.
Transportation and Storage Methods
Transportation: Packaged products are suitable for modern transport. Protect from rain, acid/alkali corrosion, and avoid heavy impact or extrusion.
Storage: Shelf life for good solderability is one year from the production date. Use within three months after opening the tape. Storage temperature: 0 ~35. Storage relative humidity: <70%.
Usage Precautions
Multilayer ceramic capacitors (MLCCs) may experience short circuits, open circuits, smoke, fire, or explosion under harsh operating conditions exceeding specified frequencies or external mechanical stress. Always follow the specifications provided. Consult the technical, quality control, or production departments for clarification.
Soldering Considerations:
- Solder Amount: Too much solder can cause damage due to excessive terminal pressure. Too little solder may result in insufficient fixing force and poor contact.
- Recommended Solder Amount: Refer to datasheet for optimal amounts for reflow, wave, and rework soldering.
Recommended Soldering Temperature Curves:
Reflow Soldering: Peak temperature: 230 ~250 (Pb-Sn), 240 ~260 (Lead-Free). Peak time: 3s10s.
Wave Soldering: Peak temperature: 230 ~260 (Pb-Sn), 240 ~270 (Lead-Free). Peak time: Within 3s.
Hand Soldering: Use caution to avoid localized heating causing micro-cracks or explosions. Use appropriate tip size ( 1mm), temperature ( 350), power ( 20W), and time ( 3s). Ensure tip does not directly contact the ceramic body. Preheating: 130.
