ADDITIONAL INFORMATION
A performance alternative to conventional capacitors for across-the-buss power applications including
motors, electric vehicles, controllers, high power converters and power conditioning systems.
The LO-HENRY© 88 SERIES provides the marketplace with a high performance snubber
capacitor within a conventional package. The MP88/PT88’s dual element design with no internal
wire connections provides a higher degree of reliability. Uses encompass a wide range
of motor applications, electric vehicles, controllers, high power converters and power conditioning
systems.

TOLERANCE
Standard tolerance is ± 10%. Tolerances of ±5%, and ±20% also available. K
Marking And Date Code
All capacitors are marked with company initials "EC", corporate logo or EC trademark—in addition to type MP88/PT88, capacitance,
tolerance, rated DC working voltage and date code. The two digits of the date code represent the year, the second two digits the
week, i.e., 0952 is the 52nd week of 2009, 0902 is the second week of 2009.
Quality Assurance
Major emphasis is placed on quality assurance. EC is an ISO 9001-2000 and AS9100:2004 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.
