Offering design engineers high density circuit protection, AVX recently extended its TransGuard® Series of bi-directional transient voltage suppressors with the introduction of a dual-element 0405 MultiGuard® multilayer ceramic transient voltage suppression array. This line of surface mount chips offer the equivalent of two separate 0402 varistors, or four back-to-back diodes with two EMI capacitors. The MultiGuard Series chips are based on AVX's proven multilayer varistor technology, providing bi-directional ESD protection, EMI attenuation and sub-nanosecond response time.
The miniature MultiGuard Series 0405 chip arrays are available in 5.6, 14 and 18 volts, with a 0.02 J energy rating, and a typical capacitance range from 40 pF at 14 V and 18 V to 360 pF at 5.6 V. The 0405 chips are rated for operation over the full temperature range from -55°C to +125°C.
The 0405 MultiGuard Series chip arrays are packaged in seven-inch reels in 1,000 piece quantities, and are compatible with high-speed pick and place equipment.
