SM1003 MELF PIN Diodes

This line of ‘MELF’ high power PIN diodes are hermetically sealed surface mount packaged devices with full face bonded chips for low inductance construction. The MELF ceramic package has square end terminations which are ideal for surface mount and pick and place operations. The PIN diode chips are coated with a special hard glass passivation which is requir.
