Capacitors target inverter solar market

The most common application is the inverter solar market, but they excel in other inverter applications where a low profile is required. The lead spacing and compact size are conducive for low inductance (<1nH per mm of lead spacing), and they’re available with single or dual leads.

The low-profile version offers a capacitance range of 13uF to 66uF, has a ±10% tolerance and comes in 450VDC and 850VDC. The terminals are tin-plated copper wire and mounted in PCB through hole. ASC Capacitors MEC-DL Low-Profile DC Film Capacitors are custom ordered only.

Custom sizing on all lines is always an option. New Yorker Electronics now maintains the full MEC-DL line, with the standard MEC-DL Capacitor series, the MEC-DL Metallised Polypropylene High Humidity Resistant Film Capacitors and the Low-Profile DC Film series.

Noted for its low ESR and dry construction, the series has a capacitance range of 10uF to 100uF and voltages of 450VDC, 850VDC and 950VDC. These can be used in arrays for bulk capacitance when needed for placement around high frequency circuits. The film is also segmented to minimise capacitance loss.

ASC’s MEC-HDL High Humidity Resistant Metallised Propylene Film Capacitors for DC Link are similarly high-frequency and high-stability and are used in DC Linking and Filtering and inverter circuits for appliances.

But with their high tolerance for high humidity, they are also used for industrial power supplies, wind power generation and solar inverters. They also feature self-healing and fuse action for higher safety at end of life.
