TDK Corporation (TSE:6762) extends its X2 safety film capacitor portfolio with the new B3292xU/V series,
now supporting higher voltages and offering compact lead spacings of 15 mm and 22.5 mm, with capacitance values from 47 nF to 1.8 µF. Rated at 350 V (AC) and robust against peak voltage pulses up to 2.5 kV
(IEC 60384-14), the series is designed for interference suppression in demanding, space-constrained industrial and automotive environments in series with the mains. Typical applications are on-board chargers, EV charging systems, PV inverters, energy meters, and capacitive power supplies.
The entire series is now available with lead spacings from 15 mm to 52.5 mm, covering capacitance values from 47 nF to 20 µF. It passed the THB (temperature, humidity, bias) test at +85 °C, 85% RH, and rated voltage for 1000 h, meeting Grade III, Test Condition B requirements. In addition, the series offers AEC-Q200 compliance, excellent self-healing properties, and a maximum operating temperature of +110 °C, ensuring durability even under severe ambient conditions.
With their compact dimensions and high DC testing voltage (1505 V for 2 s), the B3292xU/V series provides a balanced solution of performance and size for next-generation industrial drives and automotive power electronics, supporting the growing need for efficient and space-optimized EMI suppression solutions.
For the B3292xU/V series, TDK offers a range of design tools and SPICE models.
