Features Of The Surface Mount Varistor

 

* Wide operating temperature -40~+125C

* Available in tape and reel packaging for automatic pick-and-place

* Certificated by CQC UL TUV

* Surface mount devices 

* Fully automatic production line

 

 

Applciation Of The Surface Mount Varistor

 

Varistors can be used as suppressors to protect devices and circuits from transient abnormal voltages including an ESD (electrostatic discharge) and a lightning surge. For protection from a relatively large surge current (100A to 25kA), leaded disk varistors and SMD disk varistors are suitable.

Highly Recommended:
1. In the drawing board, it is recommended that the A solder joint be used as the L line, the B solder joint

as the N line, and the copper skin connected to the B solder joint is routed around the pressure-sensitive

chip circle (the entire diameter D should be regarded as belonging to the A solder joint.

2. For the sake of safety arcing, the circular edge of the chip should be at least 2.5mm away from any other

conductive device, as shown in the figure above (in order to prevent mutual displacement with other devices

during patching, if the space allows, please reserve the larger the interval is. Okay.)
3. The use of varistors in DC circuits has unfavorable factors. It is not recommended to use varistors in

rectified DC circuits. Please consider carefully or contact our company at 18128566098 (sales1@ampfort.net),

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
Forestage Varistor Parameter Back-end Varistor Parameter Remarks
110VAC±20% 270VDC±10% / In view of the insufficient voltage withstand capability of the IC, the two-stage varistor can be upgraded to 4KV lightning protection. The user can choose the varistor size according to the requirements of the anti-surge level.
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.

The picture above shows the approximate trend of the reflow oven temperature curve on the market. Our

SMD pressure sensor uses the silver electrode of the ceramic body as one of the welding electrodes.

Please pay attention to setting the oven temperature and time (if the highest temperature is 260°C,

please Note that the time is 3-8S, if it exceeds 30S, the protection effect of the varistor will be affected).
