# # # DCDC Converter Bulk Input Filter SWCH Comps # ------------------------------------------------- # # # Original Rev. 24-Jul-2015 # Most Recent Rev. 30-Jun-2016 # # # # This file holds all of the shared Bulk Input Filter # capacitors for the DCDC Converters on the Hub Module. # These filter capacitors are on the Isolated +12 Volt # bus. # # # Two types of components that are used in the # Bulk section of the Input Filter are the following: # # T520V226M020ATE040 22 uFd 20V 40 mOhm V case # 2.2 Rip Amps 1.9 mm thick # rated for continuous operation # at 80% of Vr at up to 105 deg C. # # C1206C106K3RACTU 10 uFd 25V 1206 X7R # 1.8 mm thick # # # Notes: # # These filter capacitors also help control the noise # on the Iso +12V bus that runs up to the ROD on MegArray # connector #1. # # Each of the DCDC Converters also has its own private # higher frequency input filter capacitors. # # # Finally the smallest group of the Bulk Input Filter # capacitors under the ATCA Powr Entry module for # the DCDC5 SWCH_1V2 SWITCH converter. # # # Board_Location # Ref Part_Number Symbol Geometry X Y Properties #----- ----------- ------ ------------------ -------------- ---------- # C2797 Cap_10_uFd_25_V_1206 SY_JUNK Cap_1206_THD -2.80 0.00 2 0 C2798 Cap_10_uFd_25_V_1206 SY_JUNK Cap_1206_THD 2.70 0.00 2 0 C2799 Cap_10_uFd_25_V_1206 SY_JUNK Cap_1206_THD 8.20 0.00 2 0 C2800 Cap_10_uFd_25_V_1206 SY_JUNK Cap_1206_THD 13.70 0.00 2 0 C2649 Cap_22_uFd_Tant_V SY_JUNK Tant_V_THD 0.00 5.00 2 0 C2650 Cap_22_uFd_Tant_V SY_JUNK Tant_V_THD 11.00 5.00 2 0
