EPCOS humidity-resistant X2 EMI capacitors available from Anglia

TDK Corporation presents a new series of EPCOS X2 EMI suppression capacitors with stable capacitance values, even under extremely humid conditions. The B3292*H/J* series for operating voltages of up to 305 V AC comprises types with 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. In addition, the 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.

  • Stable capacitance values even under extremely humid conditions
  • Excellent self-healing properties
  • High maximum operating temperature up to +110°C

The 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.
