CASE 5 - COMPUTER/MOBILE - AUDIO PROTECTION PROTECTION NOTES An ESD event can result in damage to the device through contact or air discharge through the audio port on the wearable devices. Because audio signals can range from 10Hz to 10kHz, MLA/MHS/MLE devices help shunt ESD away from sensitive circuitry without inducing signal distortion. Key Parameters Application Condition Requirement for MLV Continuous Voltage Rating 5VDC Varistor voltage higher than 16VDC Device size Customer may need compact design, SMD PCB mounting 0402 or 0603 Energy and Peak Current IEC 61000-4-2 requirement 8kV Contact Discharge Clamping Voltage Application testing may be needed to meet IC damage level. Application testing may be needed Suggested Series Datasheet Link MLE Note: This example is only for ESD threats; please refer to other example for other types of surges. 2016 Littelfuse Multilayer Varistors (MLVs) Design Guide Surface Mount Multilayer Varistors (MLVs) Design Guide Application Examples (continued) 11
