Description
Cooper Bussmann
®
MLVB Series of multilayer varistors are designed to
protect electronic circuits from ESD damage. The MLVB Series has the low
capacitance necessary to protect a wide range of data speeds, including
protection against high speed transient voltages.

* Part numbers use “R” to denote decimal point for decimal values of pico farads.
Features
• Zinc oxide based ceramic chip
• Low capacitance to meet the need for high speed transient voltage
protection
• Provides ESD protection with fast response time (<1ns) allowing
equipment to pass IEC 61000-4-2 Level 4 Test
• Low profile designs for board space savings
• Low and stable leakage current reduces power consumption
• Low clamping voltage
• Lead free, halogen free and RoHS compliant for global applications
Packaging
• Size 0402: 10,000 pieces per reel - EIA (EIAJ)
• Size 0603: 4000 pieces per reel - EIA (EIAJ)

* Maximum peak current across the varistor with 8/20μs waveform and 0.5A pulse current.
Working Voltage (Vdc) - Maximum DC operating voltage the varistor can maintain and not exceed 10μA leakage current.
Varistor Voltage - Voltage across the device measured at 1mA DC current. Equivalent to VB, “breakdown voltage.”
Clamping Voltage - Maximum peak voltage across the varistor with 8/20μs waveform and 1A pulse current.
Capacitance - Device capacitance measured with zero volt bias 1Vrms at 1MHz.
