5 / 21 page Approval sheet Page 5 of 7 ASC_VH0201 Green Series- V04 Aug.2018 2. Resistance to soldering heat-High Temperature Resistance:260℃, 10 sec-3times. 3. Hand Soldering In hand soldering of the Varistors. Large temperature gradient between preheated the Varistors and the tip of soldering iron may cause electrical failures and mechanical damages such s crackings or breakings of the devices. The soldering shall be carefully conditions for hand solding. 3-1 Recommended Soldering Condition 1 (1) Solder : 0.12~0.18mm Thread solder (Sn96.5:Ag3.5) with soldering flux in the core. Rosin-based and non-activated flux is recommended. (2) Preheating The Varistors shall be preheated so that Temperature Gradient between the devices and the tip of soldering iron is 150℃ or below. (3) Soldering Iron Rated Power of 20w max with 3mm soldering tip in diameter. Temperature of soldering iron tip 380℃max,3-5sec ( The required amount of solder shall be melted in advance on the soldering tip.) (4) Cooling After soldering. The Varistors shall be cooled gradually at room ambient temperature. 3-2 Recommended Soldering Condition 2(Without preheating) (1) Solder iron tip shall not directly touch to ceramic dielectrics. (2) Solder iron tip shall be fully preheated before soldering while soldering iron tip to the external electrode of Varistors. 4. Post Soldering Cleaning 4-1 Residues of corrosive soldering fluxes on the PC board after cleaning may greatly have influences on the electrical characteristic and the reliability (such as humidity resistance)of the Varistors which have been mounted on the board. It shall be confirmed that the characteristic and the reliability of the devices are not affected by the applied cleaning conditions. 4-2 When an ultrasonic cleaning is applied to the mounted Varistors on PC Boards. Following conditions are recommended for preventing failures or damages of the devices due to the large vibration energy and the resonance caused by the ultrasonic waves (1) Frequency 29MHz max (2) Radiated Power 20w/lithr max (3) Period 5minuets max ORDERING CODE VH 0201 M 050 C G T 330 Type Code Chip Size Style Rated Voltage Control Code Termination Packing Capacitance Code (pF) Internal Code V: Walsin Varistor H: High Speed or RF 0201 0402 0603 M: Multilayer A: Array 050 = 5.5V 120 = 12V C: Capacitance control code for ESD protection varistor G:Green Material T: Reeled B: Bulk Two significant digits followed by number of zeros 2R5 = 2.5pF (when C< 10pF) 100 = 10 x 10 0 = 10pF 150 = 15 x 10 0 = 15pF 220 = 22 x 10 0 = 22pF 330 = 33 x 10 0 = 33pF 560 = 56 x 10 0 = 56pF 101 = 10 x 10 1 = 100pF Blank: None N: New item Minimum Ordering Quantity: 15000 pcs per reel. |
