Temperature Peak Preheating Heating For soldering (Example : Sn-37Pb) Preheating Main heating Peak Temperature 140 °C to 160 °C Above 200 °C 235 ± 10 °C Time 60 s to 120 s 30 s to 40 s max. 10 s For lead-free soldering (Example : Sn/3Ag/0.5Cu) Temperature Time Preheating 150 °C to 170 °C 60 s to 120 s Main heating Above 230 °C 30 s to 40 s Peak max. 260 °C max. 10 s Time ● Flow soldering · Chip EMI Filters cannot be mounted on a printed circuit board by flow soldering. Mount them by reflow soldering. <Repair with hand soldering> ● Preheat with a blast of hot air or similar method. Use a soldering iron with a tip temperature of 350 °C or less. Solder each electrode for 3 seconds or less. ● Never touch this product with the tip of a soldering iron. Safety Precautions The following are precautions for individual products. Please also refer to the common precautions for Noise Suppression Device shown on this catalog. 1. Use rosin-based flux or halogen-free flux. 2. For cleaning, use an alcohol-based cleaning agent. Before using any other type, consult with our sales person in advance. 3. Do not apply shock to Chip EMI Filters (hereafter called the filters) or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, their bodies may be chipped, affecting their performance. Excessive mechanical stress may damage the filters. Handle with care. 4. Avoid applying static electricity to the filters. 5. The performance of the filters deteriorates in a circuit that is susceptible to surges or other abnormal voltages. Carefully check the circuit operations before use. 6. Store the filters in a location with a temperature ranging from –5 °C to +40 °C and a relative humidity of 40 % to 60 %, where there are no rapid changes in temperature or humidity. 7. Use the filters within a year after the date of the outgoing inspection indicated on the packages. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. 02 Nov. 2012
