Description
The MADP-000235-10720T is a surface mountable PIN
diode in a non-magnetic Metal Electrode Leadless Faced
(MELF) package. MADP-000235-10720T incorporates
M/A-COM’s time proven HIPAX technology to produce a
low inductance ceramic package with no ribbons or wires.
The package utilizes M/A-COM’s unique non- magnetic
plating process that provides for a hermetically sealed
package with extremely low permeability. Incorporated in
the package is a passivated PIN diode chip that is full
face bonded on both the cathode and anode to maximize
the surface contact area for lower electrical and thermal
resistance.
The
chip
and
package
have
been
comprehensively characterized both electrically and
mechanically to ensure repeatable and predictable
performance.
Application
The MADP-000235-10720T is designed for circuit
protection and tuning of RF coil designs in MRI
applications. When connected in an anti-parallel
configuration these PIN diodes provide protection from
long RF pulses and spikes.
MELF Internal Construction
Designed for Automated Assembly
This SMQ PIN diode has been designed for high
volume tape and reel assembly. The rectangular
package design provides for highly efficient automatic
pick and place assembly techniques. The parallel flat
surfaces are suitable for key jaw or vacuum pickup
techniques. All solderable surfaces are tin plated and
compatible with most reflow and vapor phase soldering
methods.
RoHS
The MADP-000235-10720T is fully RoHS compliant
meaning it contains less than the maximum allowable
concentration of 0.1% by weight in homogenous
materials for lead, hex chrome, mercury, PBB, PBDE,
and 0.01% of cadmium
