MIL-PRF-27F, for Level M, Grade 5, Class S
Many standard PakTM inductors and their variations have been modified on a custom part number basis to meet the following specifications:
Life tests performed for 1,000 hours at 130˚C. Thermal shock, mechanical shock and vibration.
Vibration tests that include a 20G peak varied logarithmically between 10-2,000Hz, scanned in + X, Y and Z directions at 20 minutes per frequency cycle for a total of approximately 12 hours.
QTR-Paks and 8th-Paks have completed tests. Mini-Paks are in process but not yet approved for MIL-PFR-27.
Such tests are possible only because of the SMT structure that is sound in its design: Reliable.
Up to 4,000V Isolation
Perhaps you have an application that needs the inductance of one from the standard Pak list of specifications but needs a higher isolation voltage.
Turns ratio of 1 to whatever
Standard Pak families are 1:1 transformers / dual inductors but there is no reason this ratio could not be incrementally varied to meet your specific need – quickly and efficiently.
Whether you need a variation on the standard 1:1 ratio for a SEPIC dual inductor or flyback transformer, we can do that for you – quickly and efficiently.
If your 1:1 application could benefit from lower DCR on one side of the circuit than the other – we can do that as well.
Transformers with different cores?
Would your application benefit from a different core such as Kool-MU® or other?
Current Sense Transformers?
See the Current Sense transformers section of this catalog.
Magnetics put into Pak SMT structures provide space efficiency as well as reliability.
100/year or 100,000/month?
BH Electronics has the multiple capabilities of small or large volume manufacture.
