Off-the-shelf “flying lead” and surface mount broadband conical inductors, Figure 1 and Figure 2, are a special type of broadband RF choke that are used to filter radio frequency (RF) and microwave frequency interference from electronic circuits. At high frequency, the RF choke becomes a high impedance element used to isolate noise or DC from desired signals.

Satellites with ESA as end customer and a prime contractor. This is a procurement approach where the agent receives the purchase orders for parts from various parts users, extracts and compiles the total need quantities per type and manufacturer, along with the necessary attrition (including DPA, LAT or QCI and radiation samples) and places the purchase orders at the corresponding manufacturers. Upon receipt of the flight parts by the CPPA, the ordered parts quantities will be tested as required and shipped to the individual users. The main features of the co-ordinated procurement are:
