Non-Magnetic MELF for MRI

The MA4P7461F-1072T is a surface mountable PIN diode in a non-magnetic, Metal Electrode Leadless Faced (MELF) package. The device incorporates MACOM's time proven HIPAX technology to produce a low inductance ceramic package with no ribbons or whisker wires. Incorporated in the package is a hard glass passivated, CERMACHIP™ PIN chip that is full face bonded on both the cathode and anode to maximize surface area for the lowest electrical and thermal resistance. The package utilizes a nonmagnetic plating process that provides for a package with extremely low permeability. The MA4P7461F-1072T has been comprehensively characterized both electrically and mechanically to ensure repeatable and predictable performance. The non-magnetic MA4P7461F-1072T is the electrical equivalent of its magnetic counterpart the MA4P7001F-1072T. This diode is well suited for use in low loss, low distortion, high power switching circuits and can be used in high magnetic field environments at HF through UHF frequencies. The low thermal resistance of this device provides excellent performance at high RF power incident levels, up to 100 watts CW. This device is designed to meet the most demanding electrical and mechanical MRI environments.
