Circumstance: Avoid corrosive circumstances (Ammonium, Sulfur, Halogenic gases) that can erode solder plating and cause open circuits.
Soldering Iron Operation: Apply soldering iron slowly. Tip temperature below 310 , time within 3 s. each. Limit application to the same point to 2 times.
Reflow Soldering: Pre-heat 140 to 180 for 60 to 120 s. Reflow peak temperature 2555 for a maximum of 5 s. Maximum 2 times.
Positioning: Lay out products to minimize impact from board bend or deflection. Avoid installation near dividing lines or prone to strains.
Coating Treatment: Resin burying or coating may significantly change resistance. Check material before use.
Thermal Effect Design: Confirm thermal effects in using conditions as resistors are heat-up parts.
Power Derating: Consider self-fever, ambient temperature, and heat influence from other parts. Apply sufficient load derating for long-term stable use.
Shock to the Resistor: Adjust surface mounter settings to avoid damaging the resistor. Avoid dropping.
Solder Mask and Solder Volume: Product may float on solder if solder volume is excessive, leading to higher resistance. Recommended solder mask thickness is approximately 0.1 mm.
General Use: Products are designed for general standard use in electronic equipment. For critical applications (transportation, medical, aerospace, etc.), design fail-safe systems and ensure safety measures.
