RALEIGH, NC (May 4, 2004) - SEI Electronics, Inc. has developed a series of extremely robust, lead free surface mount varistors capable of clamping voltages from 50Vdc to 385Vdc, in industry standard 3225 and 4032 package sizes.
Designated the DV and PV Series, these varistors offer low voltage and AC line-transient suppression protection to customers that traditionally utilize leaded varistor technologies.
The DV Series, are ceramic-based, chip style SMD devices capable of continuous working voltages from 11 to 300 Vrms with 8/20 µs of peak current handling of 100, 250, 400 and 1200 amps at operating temperatures from –55°C to +125°C.
The PV Series, is high polymer plastic mold-encapsulated SMD technology, capable of continuous working voltages from 11 to 300 Vrms with 8/20 µs of peak current handling of 100, 250, 400 and 1200 amps while operating at temperatures from –40°C to +85°C.
SEI Product Manager, Kory Schroeder, commented, “These varistors offer customers that are currently using through hole technologies an excellent low to medium voltage surface mount option with the same electrical parameters. The DV and PV are great choices for applications requiring higher operating temperatures (up to 125°C) and shorter response times.”
The DV and PV Series both employ a proprietary materials technology to ensure excellent clamping response times of typically less than 3 nanoseconds and 5 nanoseconds, respectively. Additionally, the DV and PV Series ensure solid performance in even the most humid environments conditions.
Typical pricing for the DV and PV Series of varistors is approximately $0.22 in quantities of 5,000 with delivery times of stock to 6 weeks. Samples are available immediately.
