BS=1500VDC, BX=1800VDC, CB=2400VDC
CAPACITANCE IN PICOFARADS

The first two digits are significant figures, the third digit represents the number of zeros

to follow to express the capacitance in picofarads.

Marking And Date Code

All capacitors are marked with company initials "EC", corporate logo or EC trademark—in addition to type HT1, capacitance, tolerance, rated 

DC working voltage and date code. The first two digits of the date code represent the year, the second two digits the week, i.e., 1252 is the 

52nd week of 2012, 1202 is the second week of 2012.

Quality Assurance

Major emphasis is placed on quality assurance. EC is an ISO 9001 and AS9100 Certified Company. Raw material inspection and the use of 

SPC manufacturing procedures assure the highest quality standards. Procedures are fully described in the EC Quality Control Manual. 

Electronic Concepts will continue to advance the state-of-the-art by utilizing leading edge technology, compact capacitor designs and 

establishing reliability procedures.

HT1  snubber  series  offers  high-temperature  performance  as  an  alternative  to  conventional  capacitors  in  applications 

including high-temperature switching to 150°C, EV/HEV inverters, and industrial power conversion. The HT1 series responds 

to  industry  demands  for  high-temperature  capacitors  with  outstanding  peak-current  performance  surpassing  traditional 

metallized dielectrics.
