VPT Releases High Temperature Product Line

May 10, 2016 | Press Releases

HTD Series Hybrid DC-DC Converters Designed for Extreme Environments up to 185°C

ALBUQUERQUE, NM – May 10, 2016 – VPT, Inc. (VPT®), a HEICO company (NYSE:HEI.A) (NYSE:HEI), released the HTD Series of DC-DC converters at the iMAPS International Conference on High Temperature Electronics, HiTEC 2016. The HTD Series of DC-DC converters, leveraging VPT’s high reliability power supply design heritage, is specifically designed for harsh and extreme temperature environments including downhole oil and gas, MWD/LWD and wireline logging tools, aircraft engine electronics and other industrial applications requiring reliable operation in high temperatures.

The HTD isolated 1.5 Watt DC-DC converter operates from -55°C to 155°C and the HTD non-isolated DC-DC converters operate from -55°C to 185°C. Each model has dual outputs and is designed using thick film hybrid microcircuit technology, bare semiconductor die integrated with passive components and thick film conductors
on a ceramic substrate. Within the HTD design, component-attach and die bonding are optimized for high temperature life, and hermetic metal packaging protects internal components for long-term reliability.

VPT’s Director of Advanced Product Development, Steve Butler, said, “We developed these products specifically for reliable performance in settings which are both high-temperature and rugged, testing them extensively for operating life and temperature cycling over the full temperature range as well as for mechanical shock and vibration.”

“Electronics for downhole and near-engine applications must operate consistently within brutal environments,” said Vice President of Sales & Marketing, Monty Pyle. “With VPT’s expertise in power supplies for space, avionics and rugged military applications, developing products for these high-temperature applications is a natural extension of our high reliability product lines.”

The HTD Series of DC-DC converters are available for immediate sale. Unit pricing begins at $700-800 (USD) for volume quantities, depending on product model. Custom versions are also available. Additional information on the HTD Series and specific product datasheets can be found at
