Precautions Before Use

MLCCs may fail in short or open circuits. Severe operating conditions or external mechanical stress can lead to burn out, flaming, or explosion. Follow specifications and contact technical support for clarification.
Soldering Conditions: Adhere to recommended temperature profiles to avoid chip cracking or local explosion due to sudden temperature changes.
Manual Soldering: Handle with care to avoid thermal shock. Ensure proper soldering iron tip selection and temperature control. Avoid direct contact of the soldering iron tip with the ceramic body.
Recommended Soldering Methods: Reflow Soldering (R), Wave Soldering (W).
Recommended Soldering Temperature Profile: Specific profiles for Reflow and Wave soldering are provided, emphasizing temperature difference control (T150) during preheating.
