What the 50 mOhm ESR means for your rail
The TPSY157K006R0050: That ESR figure is the key spec for a bulk decoupling cap on a low-voltage rail — it sets the ripple current capability and the self-heating under load.
Package and board-fit — 2917 footprint, 2.00 mm profile
The low profile — 2.00 mm max — fits under a heatsink or on the back of a densely populated board where height clearance is tight. Operating temperature spans -55°C to 125°C, covering the full industrial and military range. The molded case is rated for general-purpose use, so no special derating is needed for standard ambient conditions, but the 125°C ceiling means it survives near a hot VRM or in an enclosure with limited airflow.
The ±10% tolerance is the standard decoupling grade; if your BOM calls for tighter selection, confirm the binning before committing.
