Maximum ramping rate should not exceed 4 /sec. ℃ Maximum solder temperature should not exceed 260 ℃ Forced cooling Manual Soldering Recommendation Parameters Items Conditions Soldering condition The highest power of the manual soldering iron should be 30W or less, soldering temperature should not be higher than 280 . Soldering time The soldering time should be kept within 3 seconds, otherwise it might cause insulation layer cracking, and increased part resistance. Soldering position The distance on the leads between the soldering point and bottom of the PPTC body should be equal or greater than 4mm. Other The soldering iron should not contact the PPTC body except the leads. If the soldering conditions are kept to lower temperature, less time and larger distance, the outcome of the soldering will be better. ℃ Notes: 1. Before using the device must be stored in the original bags, if the storage conditions do not guarantee, the device may not be able to meet the given value. 2. The devices can’t used for reflow soldering. ： Revision 13-Sep-17 www.brightking.com BK250 SERIES Mechanical Characteristics Items Specifications Test Conditions/Methods Tensile strength No visible damage 1.0Kgf, 10 seconds Bending strength No visible damage 0.5Kgf, 90 , 3 times Vibration No visible damage Freq: 10-55Hz, Amp: 0.75mm, 1min ° Reliability Test Items Specifications Test Conditions/Methods Solder ability No visible damage Solder OK, Solder area ≥95% 245±5 , 2±1s, dipping depth=0.5inch max from the body Resistance to soldering heat No visible damage, Electrical OK, │△R/R0│ 50% 260±5 , 10+2/-0s Damp heat, steady state No visible damage, Electrical OK, │△R/R0│ 20% 40±2 , 90~95 % RH, total 48Hrs, after 4Hrs test electrical parameter Temperature cycling No visible damage, Electrical OK, │△R/R0│ 20% Ta -10+0/-1 30min, Ta 70+1/-0 30min, 5cycles, after 1hr test electrical parameter ， ≦ ≦ ≦ ℃ ℃ ℃ ＝ ℃ ＝ ℃ Packaging Bag Part Number Dimension A×B (mm) Quantity 120×150 1000pcs/bag 4000pcs/box BK250-030 BK250-040 BK250-060 BK250-080 BK250-090 BK250-110 Inner Box BK250-120 BK250-145 BK250-180 BK250-200 120×150 500pcs/bag 2000pcs/box BK250-400 BK250-600 150×200 BK250-800 ： Revision 13-Sep-17 www.brightking.com
