Filters Suppress EMI From 10 MHz to 10 GHz

The company's new series of two- to 56-bolt style, high-frequency coaxial EMI filters suppress EMI at frequencies from 10 MHz to 10 GHz. The filters come in C-, L-, Pi- and T-sections. The C-section filter targets circuits where both source and load impedance are high and the L-section devices are for when the application's interfering source has a low or varying impedance. The Pi-section filter is suitable for high-source and -load impedance circuits and the T-section units are for when source and load impedance are low at RF-noise frequencies. The filters meet MIL-PRF-28861 standards and are available in three working voltages: 50 Vdc and a minimum capacitance of 10,000 pF; 100 Vdc and a minimum capacitance of 5,000 pF; and a working voltage of 200 Vdc with both 2,500 pF and 1,000 pF minimum capacitances. Prices range from $3 to 5$ each/1,000.
