Automotive-grade DC-Link film capacitors withstand THB testing
AEC-Q200-qualified, metallised polypropylene devices released by Vishay Intertechnology, are optimised for high humidity environments. The Vishay Roederstein MKP1848H DC-Link automotive-grade polypropylene film capacitors withstand temperature humidity bias (THB) testing, achieving 85 degrees C, 85 per cent relative humidity for 1000 hours at rated voltage, without realising an alteration in its electrical characteristics, reports Vishay.
The radial capacitors are designed to ensure stable capacitance and ESR values over a long service life under harsh environmental conditions, explains Vishay. They are suitable for output filtering in automotive on- and off-board chargers and DC/DC converters, power converters for solar farms, auxiliary power supplies in wind energy generators, industrial power supplies and motor drives, welding equipment; and uninterruptible power supplies (UPS).
The MKP1848H DC-Link series capacitors offer rated capacitance from 1 microF to 80 microF and low ESR down to 3 mOhm. The devices provide high ripple current capabilities up to 25.1A and rated voltages of 500, 700, 800, 920 and 1200V DC at +85 degrees C. The capacitors are RoHS-compliant, halogen-free, and Vishay Green.
Samples of the MKP1848H DC-Link series are available now. Production are available with a lead time of 20 weeks.
Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). The company says its components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
