Type BLC Polypropylene Board Mount DC Link Capacitors
PCB Mount Power Film Capacitors
Type BLC series uses the most advanced
metallized lm technology for long life and high
reliability in DC Link applications. This series
combines high capacitance and very high ripple
current capability needed for today’s inverter
designs for medium power wind, solar, fuel cells,
UPS systems and more.

Determine ESR at Operating Frequency
Use the 10 kHz ESR from the ratings tables.
For operation below 10 kHz, add the dielectric resistance: ESR + 31.83 / ( fC ).
Determine Thermal Resistance at Operating Frequency and Air Flow
Compute Θ = Θ
CC
+ Θ
CA
. In the ratings tables, Θ
CC
is for ≤10 kHz and Θ
CA
is for still air.
For frequency > 10 kHz multiply Θ
CC
by [1 + (f - 10) / 100]. For v = 0 to 5 m/s, multiply
Θ
CA
by [(5 + 17(0.1

)) / (5 + 17(v + 0.1)
