Sensitive Components Chip Varistor 10D511K 510V For Surge
Overvoltage Protection
Introduction Of The Chip Varistor 10D511K
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

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.
