SMD Transient Voltage Surge Suppressors Multilayer Varistor MLA
10D271K 270V 2000A
Introduction Of The Multilayer Varistor MLA 10D271K
MLA (Multilayer Varistor), SMD transient voltage suppressor, also
known as zinc oxide varistor or "surge absorbers", is a kind of
voltage and current-voltage properties of symmetric properties
resistors. MLA is semiconducting ceramics (zinc oxide) for
materials through lamination technology (multi-layer)
manufacturing, with excellent instantaneous energy absorption
capacity, as well as fast internal thermal fugitive character, to
achieve the effect of protection circuit, also known as multilayer
varistor.

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

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. |
Because the varistor is easy to deteriorate in an environment with
large voltage fluctuations, the varistor
voltage should be selected as much as possible under the premise
that the IC (MOS tube) + lamp bead
on the lamp board has a sufficient withstand voltage and the
voltage fluctuation area is large. A
combination with a higher value should be selected, and a varistor
with a large flow and a large size
should be selected as far as possible under the premise of the
cost.
