Type 944U is specifically designed for use in medium power DC fil- tering applications. The low inductance internal construction utilizes low loss metallized polypropylene for high ripple current capability. Male or female terminal options offer design flexibility in a rugged UL 94VO rated flame retardant plastic case and resin fill.

Start by estimating: Applied dc voltage Va Ripple Current I Ripple Frequency f Ambient Temperature Ta Airflow speed v Units: A=m² T, Ta & Tc=°C C=μF θ, θca & θcc =°C/W ESR=mΩ v=m/s f=kHz Va &Vr=Vdc I=A NOTE: The temperature rise in the 944U is I²(ESR) times the thermal resistance θ. The ESR is mainly the metal resistance; the metal resistance is the 10 kHz ESR. For operation below 10kHz add the dielectric resistance. It is the dielectric dissipation factor—no more than 0.0002—times the capacitive reactance, i.e., 0.0002 ⁄(2πfC). That’s equal to 31.83 ⁄(fC). 1. Start with the 10 kHz ESR from the Ratings table. If frequency is less than 10 kHz, add 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 and 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. For moving air use the capacitor surface area A and airflow speed v to calculate 0.66 )]. 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 parallel to share the ripple current.
