This UPS540e3 in the Powermite3

rectifier that is also RoHS compliant offering high current/power capabilities

previously found only in much larger packages. They are ideal for SMD

applications that operate at high frequencies.

advantages, the Powermite3

eliminates the possibility of solder flux entrapment during assembly and a

unique locking tab act as an efficient heat path to the heat-sink mounting.

Its innovative design makes this device ideal for use with automatic insertion

equipment.

Options for screening in accordance with

MIL-PRF-19500 for JAN, JANTX, and

JANTXV are available by adding MQ, MX,

or MV prefixes respectively to part

numbers. For example, designate

MXUPS540e3 for a JANTX (consult

factory for Tin-Lead plating).

Optional 100% avionics screening

available by adding MA prefix for 100%

temperature cycle, thermal impedance

and 24 hours HTRB (consult factory for

Tin-Lead plating)
