1. Rated Current is for temperature rise of +40 ºC at 1–20 kHz.

θcc

is core-to-case thermal resistance at 0–10 kHz. For higher frequency see Expected Lifetime Predictions.

ca is case-to-ambient thermal resistance for still air. For moving air see Expected Lifetime Predictions.

Type 947C Polypropylene, DC Link Capacitors

High Current, High Capacitance for Inverter Applications

To use the Expected Lifetime curves calculate Va ⁄Vr and core

temperature T. Start by estimating:

Applied dc voltage Va

Ripple Current I

Ripple Frequency f

Ambient Temperature Ta

Airow speed v

Units:

A=m² T, Ta & Tc=°C

C=µF θ, θca & θcc =°C/W

ESR=mW v=m/s

f=kHz Va &Vr=Vdc

I=A

NOTE: The temperature rise in the 947C is I²(ESR) times the

thermal resistance θ. The ESR is mainly the metal resistance;

the metal resistance is the 10 kHz ESR. The dielectric resistance

needs to be considered for operation below 10kHz.

1. Start with the 10kHz ESR from the ratings table. If frequency is

less than 10kHz, use the following equation: ESR - 31.83/(10C) +

31.83/(fC).

2. Compute total thermal resistance θ as the sum of core-to-case

thermal resistance θcc and case-to-ambient thermal resistance

θca. Both are in the Ratings table but θca is for still air. For moving

air use the capacitor surface area A and airow speed v to calculate

θca = 1 ⁄[A(5+17(v+0.1)0.66)].

Please note that the θcc for all designs built to gures 1 and 2; θcc

is for 10 kHz or less. For frequency > 10 kHz multiply θcc by

[1+(f –10)/100], e.g., for 75 kHz multiply θcc by 1.65.

3. Compute Va ⁄Vr and the core temperature T.

T = Ta + I²(ESR)θ

4. Look up estimated lifetime from the Expected Lifetime curves.

5. If you want a longer expected lifetime, choose a capacitor with

higher voltage rating or consider using multiple capacitors in

Expected Lifetime Predictions

The expected lifetime predictions assume no exposure to overvoltage transients.

Expected lifetime can be calculated for varying exposure to overvoltage transients.
