Note: Please note NRLCW product series is specifically designed for use in commercial & consumer applications. For mission critical or industrial
applications, NIC recommends our NRLFW / NRLMW / NRLPW / NRLRW series products. Please consult NIC product specifications available on www.
niccomp.com. If in doubt, please contact NIC to review your requirements (appreview@niccomp.com)
MECHANICAL CHARACTERISTICS:
1. Safety Vent:
The capacitors are provided with a pressure sensitive safety vent on the top of can. The vent is designed to rupture in the event that high internal
gas pressure is developed by circuit malfunction or mis-use like reverse voltage.
2. Terminal Strength:
Each terminal of the capacitor shall withstand an axial pull force of 4.5Kg for a period 10 seconds or a radial bent force of 2.5Kg for a period
of 30 seconds.

Notice for Mounting
The space from the top of the can shall be more than (3mm) from chassis or
other construction materials so that safety vent has room to expand in case
of emergency.
