DC-LINK Capacitor
The capacitor has the advantages of low self-inductance, low impedance, long life, low capacity loss, good self-healing, high-current impact resistance, and fast charging and discharging speed. It is suitable for photovoltaic inverters, wind power converters, frequency converters, etc., and helps DC circuit filtering.

The rated voltage indicated for the capacitor is the maximum DC voltage at which the capacitor can be operated continuously over the entire temperature range of the capacitor (-40°C to 85°C). Maximum DC voltage.
Make sure that the ripple current and pulse current are within the permissible range when using the product. Otherwise, there is a risk of breaking the capacitor.
Despite the use of fire-resistant epoxy resin or plastic shells as fire-retardant materials in the outer package of film capacitors, external. Continuous high temperature or flame can still deform the capacitor core and cause rupture of the outer package, resulting in the capacitor core melting or burns.
● Humidity, dust, acid, etc. will have a deteriorating effect on capacitor electrodes and must be paid attention to.
● Especially avoid high temperature and humid places, the storage temperature should not exceed 35℃, humidity should not exceed 80%RH, and the capacitors should not be directly exposed to water or moisture to avoid water intrusion and damage.
● Can not be directly exposed to water or moisture, so as to avoid moisture intrusion and damage to the capacitor.
● Avoid drastic temperature changes, direct sunlight and corrosive gases.
● For capacitors that have been stored for more than one year, please check the electrical performance of the capacitors before using them again.
● The humming sound of a capacitor is due to the vibration of the capacitor film caused by the Coulomb force of the two opposite electrodes.
● The more serious the voltage waveform and frequency distortion through the capacitor, the greater the humming sound produced. But this hum.
● The humming sound will not cause any damage to the capacitor.
The terminal block should not be twisted or bent in any way to avoid breakage or other phenomena. Please check the appearance and electrical performance of the capacitor and make sure there is no damage before reuse. Please check the appearance and electrical performance of the capacitor and make sure there is no damage before reuse.
Despite the safety design of the capacitors, the insulation of the capacitors may be damaged if they are subjected to overvoltage and overcurrent or abnormally high temperatures, or at the end of their product life.
● The insulation of the capacitor may be damaged when it is subjected to overvoltage and overcurrent or abnormally high temperature or at the end of its life. Therefore, if smoke or fire occurs during the operation of the capacitor, disconnect it immediately.
● When smoke or fire occurs during operation of the capacitor, the power supply should be disconnected immediately to avoid accidents.
