Note: Please note NRLC product series is speciﬁcally designed for use in commercial & consumer applications. For mission critical or industrial applications,

NIC recommends our NRLF / NRLM / NRLP / NRLR 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

Please review the notes on correct use, safety and precautions found on

pages T10 & T11 of NIC’s Electrolytic Capacitor catalog.

Also found at www.niccomp.com/precautions

If in doubt or uncertainty, please review your speciﬁc application - process

details with NIC’s technical support personnel: tpmg@niccomp.com

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.
