I. Dimensions, Appearance Identification and Packaging (mm)
1,In the drawing buard, it is suggested to regard A solder joint as Lline, B solder joint as N line, and wire the copper foih counected widl B solder joint around the pressure sensitive chip (the whole dliameter D should be regarded as belonging to A solder joint).
2,For the sake of safety arcing, the circular edge of the chip shall be at least 2.5mm away from any other conductive devices,as shown in the figure above (in order to prevent mutual displacement between the chip and other devices, if space permits, the larger the space, the better)
3,There are unfavorable factors in the use of varistor in DC circuit.It is not recommended to use varistor in DC circuit
after rectification. Please consider it carefully or contact our company telephone 13925862052 directly. Thank you!

For different voltage application environments, we recommend the following pressure sensitive combinations to provide overvoltage, surge and lightning stroke protection for ACLED.
| Working Voltage Environment | Last-level Pressure Sensitive Parameter | Next-level Pressure Sensitive Parameter | Remarks |
|
110VAC±20% |
270VDC±10% | . Tow levels of pressure sensitive combinations can be improved to 4KV lightning protection; user can select pressure sensitive volume as needed. | |
|
220-230VAC±20% |
510VDC±10% |
470VDC±10% | |
|
240VAC±20% |
560VDC±10% |
510VDC±10% | The combination is recommended for users in Indian and Brazil. |
Since pressure sensitive resistor is easy to degrade under the environment with strong voltage fluctuation, it is required to select the combination with high pressure sensitive voltage value as much as possible under the premise that withstand voltage of IC (MOS tube) +lamp bead on lamp board is pretty high and that voltage has a large fluctuation area; besides, it is necessary to select pressure sensitive resistor with large circulation and volume as far as possible, without exceeding cost limit.
,Acceptance
Sampling should follow GB2828-87 and this Specification.

Curve diagram of wave soldering
The figure above shows the general trend of reflow soldering furnace temperature curve in the market. Our chip varistors use silver electrode of porcelain body as one of the welding electrodes. Please pay attention to the setting of furnace temperature and time (if the maximum temperature is 260℃, please note that the time is 3-8s. If it exceeds 30s, the protection effect of the chip varistors will be affected)
