2. 概述
INTRODUCTION
壓敏電阻是一種具有在一定的電壓條件下支援電流急速流出的電壓-電流特性的產品。
A varistor has the volt-ampere characteristics in which current suddenly starts to flow
through the device at a certain voltage.
壓敏電阻的作用：保護在電子線路中的電子元器件免受過電壓的影響。如下圖所示，壓敏電阻並聯在電
路中起保護作用。當有脈衝(脈衝電流Is：由脈衝電壓Vs和阻抗Zs決定)施加在電路上时，脈衝電流
（Is）限制脈衝電壓在壓敏電阻的限制電壓Vc之內。
The varistors are used to protect components in electronic and electric circuits from
overvoltage. As shown in following figure, a varistor is inserted in parallel with a
circuit to be protected. When a pulse is applied to the circuit, pulse current Is, which
is determined by pulse voltage Vs and pulse impedance Zs, flows to limit the pulse voltage
to the varistor limit voltage Vc.
壓敏電阻器對脈衝的吸收
PULSE ABSORPTION BY VARISTOR
相互的關係可以用下面的公式來解釋：
The relation can be expressed by the equations as follows:
Vs=Is×Zs+Vc
∴
Vc=Vs-Is×Zs
因為Vs遠遠大於Vc，脈衝電流Is可以用以下公式求得
The pulse current Is are easily obtained by the following equation because of Vs much
larger than Vc.
Is≈Vs÷Zs
所以，由於可承受電壓大於最大的限定電壓，電路可以長时間的免於脈衝電壓的損壞。
Thus, the circuit can be protected from being damaged by pulse voltages as long as it has
withstand voltage larger than the maximum limit voltage.
由於吸收異常電壓和電流脈衝的特性，壓敏電阻可非常高效的保護電子器件。
Owing to the characteristic, the varistors are extremely effective as protecting devices
of electronic and electric equipment by absorption of abnormal voltages and lightening
pulses.

9. 安全注意事項
SAFETY PRECAUTIONS
9.1.
使用壓敏電阻器时，壓敏電阻器周圍條件（設備設計中的材料、环境、電源條件、電路條件等）發生異常时，則可能引發火災、觸電、燒傷、以及
產品故障。
In case that a varistor is used, if an abnormality takes place because of peripheral conditions of the varistor(material,
environments, power source conditions, circuit conditions, etc. In equipment design), fire, electric shock, burn, or product
failure may be occur.
下列內容為使用时的相關注意事項，请認真确認後再行使用。如對未及事項有疑議，请速與我公司擔當部門聯繫。
The precautions for this product are described below; understand the content thoroughly before usage. For more questions,
contact us.
嚴格遵守事項
Precautions to be strictly observed
9.1.1. 額定性能确認
Confirmation of performance ratings
请遵守壓敏電阻器的最大連續工作電壓，耐衝擊電流、最大能量耐量、浪湧壽命、額定功率和操作溫度範圍等額定性能的規定，在規定範圍內使用
。
Use the varistor within its rated range of performance such as the maximum continuous operating voltage, withstanding surge
current, maximum energy, impulse life, rated power and operating temperature range.
超出規定範圍使用，則會造成壓敏電阻器性能劣化，破壞元件，嚴重可引起壓敏電阻器冒煙或起火。
If used outside the range, the varistor can be degrade and have element fracture, which may result in smoking and ignition.
9.1.2. 為避免意外現象發生，请採用如下對策
To avoid accidents due to unexpected phenomena, take the following measures
1) 壓敏電阻器受損时 ，可能出現破碎飛散，因此要對整合式產品加保護蓋或外盒。
In the event of fracture of the varistor, its pieces may scatter; hence, put the case or cover of the set product in place.
2) 请勿安装在可燃物品（塑膠電線、樹脂合成物等）附近。若無法避免，请使用不燃性保護外殼。
Do not install the varistor near combustible substances (polyvinyl chloride wires, resin moldings, etc.). If it’s difficult
to do, install a nonflammable cover.
3) 線間使用
Across-the-line use
線上間使用时，將保險絲與壓敏電阻器串聯。
When the varistor is used across a line, put a current fuse in series with the varistor.
4) 線-地間使用
Use between line to ground
a) 線上-地間使用时，壓敏電阻器短路时會產生接地電阻，電流保險絲不會熔斷，可能引起壓敏電阻器外塗層樹脂冒煙或起火。
If the case that the varistor is used between a line to the ground, the short circuit of the varistor may not blow the
current fuse because of grounding resistance, which may cause smoking and ignition of the varistors exterior resin.
為避免上述情況，请在電源端安装漏電斷路器。如無漏電斷路器，則需將電流保險絲與溫度保險絲串聯使用。
As the measure against it, install an earth leakage breaker on the power supply side of the varistor position. If no
earth leakage breaker is installed, use a thermal fuse together with a current fuse in series.
b) 在帶電部件與金屬部件之間使用壓敏電阻器时，壓敏電阻器短路时有觸電危險，故请將金屬部件接地或勿與人體接觸。
If the case that the varistor is used between a live parts to metal case, an electric shock may develop at a shortcircuit
of the varistor; hence, ground the metal case to the ground or keep it from the human body.
9.2.
使用注意事項
Application notes
9.2.1. 注意下列事項，可能導致壓敏電阻器壽命縮短或引發故障
Pay attention to the following items to avoid the shortened life and failure of the varistor.
1) 電路條件
Circuit conditions
a) 選定的壓敏電阻器的電壓最大值在最大連續工作電壓值之上。
Select a varistor of which the maximum voltage including fluctuations in source voltage allows for the maximum
permissible circuit voltage.
b) 短間隔性地施加浪湧时（施加抗干擾類比試驗電壓时），不可超過壓敏電阻器的額定功率。
In cases that surges are intermittently applied at short intervals (for example, in case that the voltage of the noise
simulator test is implemented etc.), do not let them exceed the varistors rated power.
c) 選定壓敏電阻器时，須按照表1的標准產品型號
Select a varistor recommended in table 1.
① 線間使用
Across-the-line use
單相三線式連線时單獨配線負荷導致負荷不平衡、電壓線和中性線短路、中性線欠損、容量性負荷情況下開閉时的共振等，將導致電源電
壓的上升，可能使用表1中標有＊的產品型號。
If possible, use a part no. Marked with ✽ in case of voltage temporarily rises load unbalance of separately-wired
loads, short between hot and neutral-line, open of neutral line in single-phase-three-wired system, and due to
resonance at switching for a capacitive, inductive load.

9.2.3. 加工條件
Processing conditions
1) 不可採用可能導致外塗層樹脂劣化的溶劑（稀釋劑、丙酮等）进行清洗。
Do not wash the varistor by such solvents (thinner, acetone, etc) as its exterior resin deteriorates.

說明
Notices
用於可靠性要求極高的設備（航空航太設備、醫療設備等）时，请事先至本公司諮詢使用型號和保護措施等相關事宜。
In cases that the varistor is used in equipment (aerospace equipment, medical equipment, etc) requiring extremely high
reliability, ask us for a selection of part no., and protection coordination, etc in advance.
若未按照產品規格書記載事項进行操作，並由此導致出現異常时，本公司不負任何責任。
Note that we do not take any responsibility for faults and abnormalities resulting from the use not in conformity with the
contents of entries in the delivery specification.
出現使用電路電壓的異常上升、超高浪湧的侵入等不可預期因素时，可能導致壓敏電阻器起火。為防止延燒到使用設備上，外部結構材料需使用阻
燃材料进行多重保護。
There is a possibility that the varistor will unexpectedly cause smoke or ignite because of an abnormal rise of the circuit
voltage and invasion of excessive surge. To prevent that accident from spreading over the equipment and not to expand the
damage, use multiplex protection such as the adoption of frame-retardant materials for housing parts and structural parts.
