Widely used in inverters welders: The STP Series capacitors are extensively utilized in inverter welders, indicating their reliability and effectiveness in welding applications. Inverter welders are known for their efficiency and precision, and the capacitors in this series play a crucial role in their operation.
Polypropylene construction: These capacitors are constructed using polypropylene, a durable and reliable material known for its excellent electrical properties and resistance to temperature and humidity variations. Polypropylene construction ensures the capacitors can withstand the demanding conditions encountered in welding environments.
Self-healing property: One of the key features of the STP Series capacitors is their self-healing property. This means that in the event of a minor dielectric breakdown or puncture, the capacitor can recover and continue functioning without significant loss of performance. This feature enhances the longevity and reliability of the capacitors, reducing the likelihood of catastrophic failure.
Long lifetime, small inherent temperature rise: The capacitors in the STP Series are designed for longevity, with a prolonged operational lifespan. Additionally, they exhibit a small inherent temperature rise during operation, indicating efficient energy conversion and minimal heat dissipation. This characteristic contributes to the overall reliability and efficiency of the welding machine.
Tinned copper leaders filled with UL94V-0 resin: The capacitor leaders are made of tinned copper, a highly conductive material that facilitates efficient electrical connections. Furthermore, they are filled with UL94V-0 resin, a flame-retardant material that enhances the safety of the capacitors, particularly in welding applications where sparks and heat are prevalent.
Non-inductive type: The capacitors in the STP Series are of the non-inductive type, meaning they exhibit minimal inductance. This feature is crucial in welding applications where fast and precise electrical responses are required. Non-inductive capacitors ensure minimal interference with the welding current, enabling accurate control of the welding process.
Specifications:
Operating temperature range: -40°C to 85°C: The capacitors are designed to operate effectively within a wide temperature range, from -40°C to 85°C. This versatility allows them to perform reliably in various environmental conditions commonly encountered in welding operations, including both extreme cold and heat.
Storage temperature range: -40°C to 85°C: Similarly, the capacitors can be safely stored within the same temperature range of -40°C to 85°C. Proper storage conditions are essential for maintaining the integrity and performance of the capacitors, especially during transportation and warehousing.
Capacitance range: 0.047 to 35μF: The STP Series capacitors offer a capacitance range spanning from 0.047 to 35 microfarads (μF). This wide range allows for flexibility in designing welding circuits with varying capacitance requirements, catering to different welding applications and power levels.
Capacitance tolerance: ±5%, ±10%: The capacitors have a capacitance tolerance of ±5% or ±10%, ensuring that their actual capacitance closely matches the specified value. This level of tolerance ensures consistency and accuracy in welding operations, preventing deviations in performance due to capacitor variations.
Voltage range: 400 to 1200 Vdc: The capacitors are rated for a voltage range of 400 to 1200 volts direct current (Vdc). This voltage rating is suitable for welding applications where high voltages are involved, providing the necessary electrical insulation and reliability to withstand the rigors of welding processes.
