Warnings and Precautions:

• Carefully consider the maximum and minimum specification values, especially for magnetic material characteristics (AL, Bs, Pc, temperature coefficient, frequency, Tc), to correctly select FERRITE CORE material and type.
• Use suitable, non-corrosive, and non-interactive insulating materials for winding. Be careful during winding to avoid abrasion of wire insulation.
• For enhanced insulation, consider using bobbins and tape, or other neutral dielectric materials with thermal compensation similar to the FERRITE CORE.
• Avoid improper use of assembly fixtures and excessive assembly force to prevent CORE damage and chipping.
• Thoroughly clean the workspace between the coil and CORE to prevent CORE damage and insulation failure.
• Use appropriate 2-UEW specification wires for winding to prevent overheating and combustion.
• For safety, prevent damage to other circuit components caused by improper transformer assembly position and overload current.
• Follow these precautions to avoid human-induced damage during FERRITE CORE assembly:
• Handle with care to prevent breakage and chipping of FERRITE CORE and ceramic capacitors.
• Keep CORE away from strong magnetic fields.
• Avoid mechanical impact when using assembly fixtures.
• Prevent damage from thermal shock.
• Avoid direct contact between CORE surfaces during intense friction.
• Exercise caution regarding CORE weight during shipping and transportation.
• Do not reuse FERRITE COREs.
• FERRITE COREs are not edible. Keep them away from children and do not attempt to ingest them.

Effective Date: This acknowledgment will become effective one week after provision if no objection is received.
