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. 編號DOC NO.: 壓敏電阻器規格承認書 APPROVAL SPECIFICATION FOR VARISTORS DEC-SA-WI007 版本REV.: B/0 日期DATE: 2021/6/9 頁碼PAGE: 4 / 15 3. 應用 APPLICATION ■ 消費電子產品：電視機、音訊輸出設備、安全插座、機上盒等 Consumer

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.

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. 方式一 Method 1 ■ 方式二 Method 2 孔距(P0)為12.7mm，元件間距离(P)為25.4mm Feed hole pitch (P0) with 12.7mm and components pitch (P) with 25.4mm ■ 孔距(P0)與元件間距离(P)均為12.7mm 或者，孔距(P0)與元件間距离(P)均為15.0mm 12.7mm by feed hole pitch (P0) and components pitch (P) or, 15.0mm by feed hole pitch (P0) and components pitch (P) 10. 編帶標准 TAPING SPECIFICATIONS 版本REV.: B/0 日期DATE: 2021/6/9 頁碼PAGE: 15 / 15 壓敏電阻器規格承認書 APPROVAL SPECIFICATION FOR VARISTORS DEC-SA-WI007 編號DOC NO.: 进料孔與元件間距离 Hole center to component center 導線直徑 Lead wire diameter 紙帶寬 Tape width 膠帶寬 Hold-down tape width 孔位 Hole position 膠帶位置 Hold-down tape position 元件總高度 Component height 进料孔直徑 Feed hole diameter 編帶厚度 Total tape thickness 編帶總厚度（含導線） Total tape, tape and lead wire 剪切長度 Snipped length 塗装脚長度 Coating rundown on leads 彎脚架高 Height of kink P1 P2 Φd W W0 W1 W2 H H0 H1 D0 t1 t2 L C K 12.7 15.0 25.4 25.4 12.7 15.0 12.7 12.7 3.85 3.75 3.85 6.35 0.7 18.0 7.0 9.0 3.0 18.0 16.0 40.0 4.0 0.9 1.7 11.0 3.0 5.0 7.7 --- ±0.8 ±1.0 ±0.3 ±0.7 ±1.3 ±0.1 +1.0 -0.5 min +0.75 -0.5 max +2.0 -0 ±0.5 max ±0.3 max max max max max 彎脚類 元件到紙帶中心的高度 Kink lead type Height of component 直脚類 from tape center Straight lead 进料孔與導線間距离 Feed center to lead P0 10.0 7.5 7.5 --- 孔距 Feed hole pitch P 5.0 方式二 Method 2 7.5 元件間距离 Component pitch F 方式一 Method 1 標准 Specifications 誤差 Toleranc e 脚距 Lead to Lead distance 項目 代碼 Item Symbol
