    Murata - DST310 55Y5S222M100 - EMI/RFI Suppression DST310 Series Filter.

    Based on more than 30 years of ceramic and ferrite technology experience, Murata Electronics’ full range of leaded EMI filters have been designed to meet today’s electronic industry requirements. Murata’s leaded devices consist of ferrite bead inductors, feed-thru capacitors, 3 terminal capacitors, varistor/capacitors common mode chokes and block filters.

    DST310 are T-type EMI suppression filters. The disc-type EMIFIL increases the self-resonant frequency of the capacitor by attaching two lead wires to one of the electrodes of the capacitor and increases the insertion loss by adding inductance to the lead in the DST and DSS types only. Frequencies to be suppressed can be selected by choosing the capacitance. They are also recommended for use as by-pass capacitors.

    Capacitance: 2200pF

    Effective Frequency: .8 to 12000 MHz

    Working Voltage: 100V.

    Tolerance: 20%.

    Temperature: -25C to 85C
