The product didn't arrived even if I got message from seller that product is on its way. I am very disappointed.
The shipment arrived in Moscow for a month. Sufficiently high-quality capacitors. The capacity of 4.9 UF 400 V. at a frequency of 1 kHz, the loss tangent is close to zero. The angle of the phase shift of 90 degrees. At a frequency of 10 kHz, respectively, 0,002, 89,8 degrees. At a frequency of 100 kHz, respectively, 0.08-0.09, 84.8-85.5 degrees. Capacitors with a capacity of 4.9 UF 630 V. at a frequency of 1 kHz, the loss tangent is close to zero. The angle of the phase shift of 90 degrees. At a frequency of 10 kHz, respectively, 0.002, 90.0 degrees. At a frequency of 100 kHz, respectively, 0.08-0.09, 84.7-85.5 degrees.Recommended as shunt capacitors. Recommend all the store.
