Surface Mount – MELF PIN Diodes
.
D E SCRI PTI ON
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 required for high power applications and to
enhance the reliability resulting in MTBFs of greater than one million
hours.
RoHS compliant versions of these products meet RoHS requirements per EU
Directive 2002/95/EC. The standard terminal finish is gold unless otherwise
specified. Consult the factory if you have special requirements.
APPLICATIONS
The MELF diodes are used as switching, attenuating and phase
shifting elements from HF through 2 GHz and have breakdown
voltage ratings up to 500 volts. ‘Non-magnetic
1’ .Cer-Met. (MELFs)
are also used as switching elements in MRI (magnetic resonance
imaging). Conventional Magnetic MELF packages are used in
Cellular, Beam Steering units (telephone via satellites) surface mount
applications, and Filter Switch banks for Frequency Hopping Radios.
