LCR Electronics (Norristown, PA) now offers a line of single phase COTS (commercial-off-the-shelf) filters that operates over an extended temperature range of -40°C to +85°C (-40°F to +185°F). The new RoHS-compliant Single Stage F9100 Filters and Double Stage F9200 Filters are ideal for high ambient environments or in applications with limited temperature rise requirements as found in the military, industrial and medical industries.
The new 115/250 VAC 50/60 Hz filters are available with rated current from 5 A to 35 A, in both general purpose and low leakage current versions. High potential voltage for both series is 1,450 VDC line-to-line and 2,250 VDC line-toground. Depending on the filter current rating, insertion loss for the F9100 measured in a 50 ohm system for frequencies starting at 50 kHz up to 30 MHz ranges from 5 dB to 45 dB in common mode and 5 dB to 35 dB in differential mode. Insertion loss for the F9200 ranges from 5 dB to 80 dB in common mode and 10 dB to 75 dB in differential mode, under the same conditions.
