The preferred procurement channel is through the manufacturers, and if not, through duly authorised/franchised distributors, which allow minimizing the risk of delivery of counterfeit parts. In any case, a specific anti-counterfeit policy will be applied and all required test to be performed to validate the authenticity of the parts upon reception of the parts.

The objective of the EEE COTS parts procurement management is to assure the correct selection, control, procurement and usage conditions so that the EEE part meets its mission requirements. The goal is not easy, but it can be approached by putting in place different actions: data collection, risk assessment, specific testing/validation, lot traceability, anti-counterfeit measurements, lead material identification, and many more…

Paper Capacitors

Because paper is porous it has to be impregnated in order to prevent corona effects and flash-overs. It is done by use of melted wax or different kinds of oils, among other things mineral and silicone oils. The oils increase the tensional stability but decrease to a certain extent the εr. A fibrous paper has a εr ≈ 6.6 and the mineral oil ≈ 2.3 which gives the impregnated winding a εr varying between 3.1 and 4.5. The differences depend above all on the winding pressure produced by the tensile force during winding.

Pros and Cons of MLCC Downsizing

Advantages and disadvantages of MLCC downsizing are discussed in AVX technical papers written by Frank Hodgkinson and Maureen Strawhorne. As integrated circuits (ICs) continue to pack more functionality into smaller packages, the need for bulk off-chip capacitance remains. In resonant circuits, such as phase-lock-loops (PLLs) and switching regulators, precision class one ceramic capacitor may be required.
