All the “Paks” – QTR-Pak®, 8th-Pak™, Mini-Pak™ – have these features:
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.
Perhaps you have an application that needs the inductance of one from the standard Pak list of specifications but needs a higher isolation voltage.
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.
Would your application benefit from a different core such as Kool-MU® or other?
See the Current Sense transformers section of this catalog.
Magnetics put into Pak SMT structures provide space efficiency as well as reliability.
BH Electronics has the multiple capabilities of small or large volume manufacture.
Whether “custom” or standard, BH is able to quickly respond to your requirement.
If SMT size, performance and reliability are critical to your application - large or small.
