Radio interference suppression electronic filter SFK12-4S2148

low-passpassiveDC

Filters of the SFK12-4S2148 series are used to suppress circuit-bound interferences in DC supply lines or DC control lines with a voltage of 48VDC. Interference pulses or interference voltages are dampened independently from their point of origin. The integrated overvoltage protection efficiently diverts unwanted inductive transients. High insertion loss over a broad frequency range Optimised against interferences in the lower frequencies Extra slim enclosure design, only 22.5 wide Self-extinguishing polycarbonat housing acc. to UL94V1 Suitable for the tropics - epoxy resin casted Safety acc. to VDE, EN, UL, CSA Inductance: - 2 x 400µH Capacity: - 2 x 470µF + 2 x 330nF Operating temperature range: - -40°C / +85°C Dimensions (WxHxD): - 22.5 x 75.0 x 98.5 mm Weight: - 0.35 kg
