1 µF at 10 V in an 0805 — ESR drives the ripple budget
The TPSR105M010R9000: The 9 ohm ESR is the parameter that governs ripple current handling and transient response — for a 1 µF part, that ESR limits the self-heating under AC ripple and sets the voltage droop during a load step. Housed in an 0805 (2012 metric) SMD package, it fits the standard footprint for this capacitance and voltage class. The seated height of 1.20 mm keeps it compatible with low-profile PCB assemblies.
Temperature range and lifecycle — active, no obsolescence risk
The manufacturer size code R corresponds to the 0805 case dimensions (2.05 mm x 1.30 mm). Sourced to order against BOM quantities; availability and current pricing confirmed at RFQ.
