MLN SurgeArrayTM Suppressor Datasheet

Category: Electronics, Littelfuse Inc, Resistors

Description

The MLN SurgeArrayTM Suppressor, as detailed in the datasheet, is specifically engineered to safeguard electronic components against transient voltages present at the circuit board level. It features a quad-array design, consolidating four independent suppressors into a single chip. This integration simplifies installation by reducing the number of parts and saving space. The suppressors are designed to offer protection against Electromagnetic Compatibility (EMC) challenges such as Electrostatic Discharge (ESD), Electrical Fast Transients (EFT), and other transient voltage conditions, supporting components operating at voltages up to 18 V_DC. The device complies with the IEC 61000-4-2 human body model for ESD, assisting products in meeting EMC regulations. Its built-in capacitance allows it to double as a filter/suppressor, which can replace separate Zener diode/capacitor configurations. The SurgeArrayTM is manufactured using Littelfuse’s proprietary multilayer technology.
