Introduction

KEMET's VE series of high temperature, low voltage varistors are designed to protect sensitive electronic devices against high voltage surges in the low voltage region. In addition to superior operating performance at rated 150°C (AEC–Q200 compliance) they offer excellent transient energy absorption due to improved energy volume distribution and power dissipation.

Features

• AEC-Q200 qualifed Grade 1
• Surface mount form factor
• Operating ambient temperature of -55°C to +150°C
• Superior operating performance rated at 150°C (AEC-Q200 compliance)
• Operating voltage range of 11 – 170 V
• AC voltage range (Vrms) of 8 - 130 V
• High resistance to cyclic temperature stress
• Low leakage currents after 1,000 hours rated at 150°C
• High energy absorption capability
• Available case sizes: 0603, 0805, 1206, 1210, 1812, 2220
• Short response time
• Broad range of current and energy handling capabilities
• Low clamping voltage – Uc
• Non-sensitive to mildly activated fluxes
• Barrier type end terminations solderable with Pb-free solders according to JEDEC J–STD–020C and IEC 60068–2–58
• RoHS 2 2011/65/EC, REACH compliant

Applications

• Transient over-voltage protection in automotive assembly motors and controllers
• Surge protection of non-automotive electronic products exposed to over-heating, i.e., consumer, telecommunication or industrial
• Load dump and jump start protection of 12 to 24 V supply systems
• Protection of integrated circuits and other components at the circuit board level including the suppression of inductive switching or other transient events such as surge voltage
• ESD protection for components sensitive to IEC 1000–4–2, MILSTD 883C Method 3015.7 and other industry spec
