TDK's EPCOS B3292 H/J series is made up of capacitors with operating voltages up to 305 V_AC, rated capacitances ranging from 0.1 µF to 15 µF, and lead spacings from 15 mm to 37.5 mm.

The operating temperature range is from -40°C to 110°C. These capacitors, which employ a metallized polypropylene dielectric (MKP), also feature excellent self-healing properties that allow weak dielectric areas to be burned out in the event of overvoltages.

These new X2, humidity-resistant, robust capacitors perform reliably under severe ambient conditions, easily passing the damp-heat test. Here, they must operate for at least 1000 hours at a temperature of 85°C, a relative humidity of 85 percent, and a voltage of 240 V_AC without a change in capacitance of 10 percent or more. Thus, the new X2 capacitors are perfectly suited for applications in harsh environments, such as the capacitive power supplies in outdoor energy meters, for example, and in across-the-line industrial applications.
