| Description & Applications | CHIP VARISTOR Chip Varistor VCM11R/21R Series Ultra Small Size Surge Absorb Components FEATURES 1. It is effective in high density packaging, because of smaller dimension than diode which is generally used as surge countermeasure devices. 2. The small clamping voltage ratio enables effective absorption of surge noise. 3. VCM11R can be applied in high speed signal line, because its capacitance is relatively small. 4. The large peak current of VCM21R, up to 150A, enables high reliability against surge. 5. VCM21R can be applied to ISO-7637-1. Test pulse condition. 6. The nickel barrier structure of the external electrodes provides excellent solder heat resistance. Both flow and reflow soldering methods can be applied. APPLICATIONS Surge absorption in communication ports such as RS-232C Motor/relay noise absorption Electro static protection in I/O port of computers |
| 描述与应用 | 片式压敏电阻 贴片压敏电阻VCM11R/21R系列 超小尺寸的浪涌吸收元件 特点 1。在高密度封装，它是有效的，因为更小的尺寸比二极管通常被用作电涌对策设备。 2。小钳位电压比，能够有效地吸收浪涌噪声。 3。 VCM11R可以应用在高速信号线，因为它的电容比较小。 4。大峰值电流高达150A，的VCM21R，实现了高可靠性，以防止浪涌。 5。 VCM21R可以应用于：ISO-7637-1。测试脉搏条件。 6。外部电极的镍隔板结构提供了优良的焊接耐热性。流量和回流焊接方法都可以应用。 应用 如RS-232C通信端口的浪涌吸收 电机/中继噪音的吸收 在I / O端口的电脑的静电保护 |
