AC filtering film capacitors are robust in high humidity environments

Metallised polypropylene AC filtering film capacitors from Vishay Intertechnology are optimised for high humidity environments. The Vishay Roederstein MKP1847C AC filtering devices withstand demanding temperature humidity bias (THB) testing i.e. 40 degrees C, 93 per cent relative humidity for 56 days at rated voltage, without altering their electrical characteristics.

The capacitors are designed to ensure extremely stable capacitance and ESR values over a long service life under harsh environmental conditions during operation. Compared to previous generation devices, the MKP1847C AC filtering series capacitors offer higher humidity robustness at a lower cost while maintaining the same footprint. The capacitors are suitable for input and output filtering in uninterruptible power supply (UPS) systems, renewable energy inverter grid interfaces and welding equipment.

MKP1847C AC filtering series capacitors feature a wide capacitance range from 1.0 to 70µF, with tolerance down to ± 10 per cent, and rated voltages of 230V AC, 250V AC, 275V AC, 310V AC and 350V AC. The devices offer low self-inductance of less than 1.0nH per mm of lead spacing, high peak current capabilities up to 750A, and high RMS current up to 26A.

The capacitors are offered in a flame-retardant plastic case with a resin seal and have an operating temperature up to +105 degrees C.

Samples and production quantities of the MKP1847C AC filtering series are available now, with lead times of 12 weeks.

Vishay claims to manufacture one of the world’s largest portfolios of discrete semiconductors and passive electronic components for designs in the automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical markets.
