The NPDC series of capacitors from NIC Components provides a wide range of capacitance and tolerance options to give designers the opportunity to match dc filtering characteristics to the needs of the application.

NIC Components supplies the NPDC series of metallized polypropylene film capacitors which offer high reliability and stability in demanding applications. The capacitors are optimized for use in dc filtering in dc-link applications.

 

The NPDC capacitors are notable for their low ESR. The capacitors also handle high currents, providing for robust performance in power-conversion circuits. The NPDC series is AEC-Q200 qualified, ensuring high reliability and stable performance in harsh conditions in automotive and other applications.

 

The molded box construction of the NPDC capacitors produces a compact form factor which enables integration into tight spaces without compromising performance. The capacitors are available with tolerance options of ±5%, ±10% and ±20%.
