ESR of film capacitor is unstated in datasheet?

[grizedale]

Please may i confirm that there is no way of knowing what is the dissipation factor, or esr of this family of capacitors at 84KHz....

I wish to know if the 820n, 250V ECWF2824 capacitor can handle 2.4 Amps at 84KHz.

Is this the information you need: Parametric Search Electronic Components : Panasonic Industrial

If that doesn't take you directly to the charts, click on an item in the related information column, then click on temperature and other characteristics.

This page will allow you to pick other varieties of leaded film capacitors: Leaded Film Capacitors - Panasonic

Hi,

That search engine doesnt indicate what the esr might be at 84KHz.

It shows a lot of Panasonic caps.....

i couldnt assess which of those families was for lowest dissipation factor.

I thought this was the information you needed. Dissipation factor is essentially flat up to 100 KHz. Unfortunately, I couldn't get that page to link directly with my browser.

Thanks jpanhalt...thats a great dissip factor.

I am not sure where you received that information from though.

i cannot understand why that information was not in the datasheet....i mean those graphs illustrate superb behaviour of this capacitor...so now i am wondering why Panasonic are not putting those graphs in the datasheet.

The links I gave go directly to the data from which I posted just a snippet. Maybe I got a cookie or something in my PC that makes it behave differently than yours, but the click instructions should get you there.

It is not all that uncommon for manufacturers to put repetitious information in a separate document from the standard datasheet for individual components. Although you have not mentioned surface mount, you might find the last 10 pages or so of this document interesting.

AVX has several similar notes, including some directly related to SMPS.
