High Performance Quarter Bricks Target COTS and Harsh Environment Applications

San Diego, CA – June 2016 –

TDK Corporation announces the introduction of the TDK-Lambda HQA120 isolated DC-DC converters.  Rated at 120W, the HQA120 has been qualified with methods consistent with MIL-STD-883 and MIL-STD-202, making it suitable for use in COTS and harsh environment industrial equipment.  Initially available with 12V, 24V and 28V outputs, the encapsulated quarter bricks accept a wide range DC input of 9V to 40V, withstanding a 50V surge for 10 seconds. 

 A choice of two grades is offered:  -S for standard industrial applications or -M using wide temperature, high grade components and additional product testing for enhanced reliability.  This includes functional testing at low, high and room temperatures, a 96-hour extended burn-in period and 10 temperature cycles.  With typical efficiencies of up to 89%, internal heating is minimized allowing the HQA converters to operate in high ambient temperatures of up to 115oC and a minimum of -55 oC (M grade) or -40oC (S grade).  No opto-couplers are used in the design and the switching frequency is fixed at 270 kHz for simplified noise filtering.

 The converter pinout follows the industry standard five pin quarter brick footprint featuring negative logic remote on/off and +/- remote sense.  Two package styles are offered; a flanged type measuring 2.39” x 2.2” x 0.5” and a non-flanged version measuring 2.39” x 1.54” x 0.5”. 

 Input-to-output and input to baseplate isolation is 2,250Vdc (basic), and the converters are safety certified to UL/CSA/EN 60950-1 (2nd edition), carrying the CE mark in accordance with the LV Directive and RoHS Directives.
