American TRANSTEK capacitor FL612X4.0-120B – the professional choice for high voltage DC filtering
User pain points
In high-voltage DC application scenarios such as industrial power supplies, photovoltaic inverters, and new energy charging piles, engineers often face difficulties in capacitor selection: ordinary capacitors have insufficient voltage resistance and are easily broken down by high voltage; their capacity decays quickly and their service life is short; their high-frequency characteristics are poor, and their filtering effect is unsatisfactory.These problems not only affect the stability of the equipment, but may also cause the entire system to malfunction, resulting in high maintenance costs.
Product Solutions
The FL612X4.0-120B high-voltage film capacitor launched by TRANSTEK in the United States is specially designed for 1200V high-voltage DC filtering scenarios.This product uses high-quality metallized polypropylene film as the medium, combined with advanced winding technology and vacuum impregnation technology to ensure stable performance in harsh working environments.The nominal capacity of 4μF and the capacitance accuracy of ±10% can meet the precise needs of most high-voltage filter circuits.
Selling Points and Value
Ultra-high voltage guarantee: 1200V rated voltage with sufficient design margin, it can operate safely even under power grid fluctuations or transient overvoltage conditions.
Excellent frequency characteristics: The unique low ESR and low ESL characteristics of film capacitors make them perform well in kHz-level high-frequency switching power supplies, and the filtering effect is far better than traditional electrolytic capacitors.
Super long service life: No liquid medium design, strong temperature adaptability, wide operating temperature range, and the service life can reach more than 100,000 hours under normal use conditions.
Stable and reliable: The metallized film has a self-healing function, and local breakdown can be automatically repaired to ensure long-term stable operation.
Application scenarios
This product is widely used in:
- Photovoltaic inverter DC-Link filter circuit
- High voltage filtering for electric vehicle charging piles
- Industrial switching power supply filtering
- Rail transit traction system
- Wind power converter filter circuit
If you are looking for a reliable high voltage DC filter capacitor, TRANSTEK FL612X4.0-120B will be your ideal choice.
