Murata has announced the DE1 Type RB series of X1 class leaded ceramic safety capacitors. Suitable for use in high voltage industrial applications such as 3-phase power supplies or inverters driving 3-phase motors, the series is rated at 760VAC (RMS) for X1 class use. The DE1 complies with the internationally recognised standards IEC 60384-14, UL60384-14 and EN60384-14 for X1 / Y1 class capacitors used in EMI suppression circuits.
With its compact dimensions, the capacitor also aids reducing the overall space requirements of the application. It is also rated with a high maximum operating temperature of 125°C, permitting it to be placed close to the source of the electromagnetic noise.
The DE1 series can also be used as a Y1 class capacitor for connecting between an AC power line and ground, for which it is rated at 500VAC (RMS).
Available in standard values from 10-4,700pF, the DE1 series has value-dependent dimensions from 6.0-14.0mm outer diameter.
