QPL Components
SESI 9.1WR
series are usually installed on Military applications and breadboards for Space applications.
Since January 2003, Microspire has been manufacturing Radio Frequency Fixed Coils,
SESI 9.1WR
series fulfilling
ESA ESCC
Generic specification
N°
3201
and detail specification
N°
3201/009.
This qualification approval includes final production tests Chart II, burn-in and electrical measurements to testing
level B Chart III and qualification testing Chart IV.
For procurement, different quality levels are offered :
• Final production tests Chart II
• Burn-in and electrical measurements Chart III with level B or C (as required)
• Lot acceptance testing Chart V if required
Components delivered through this specification need to be processed and inspected in accordance with the
Microspire Process Identification Document (P.I.D.).
Each component delivered is traceable to its production lot.
The terminal material and finish shall be brass, plated with
2
to
4
µm of Nickel, the finish shall be either
Sn60Pb40
or
Sn90Pb10.
