What the 25 mOhm ESR buys the POL designer
The TPME227K016R0025: The 25 mOhm ESR at 220 µF and 16 V is the number that sets the ripple current rating — for a point-of-load converter switching at 500 kHz, this cap can sink the inductor ripple without exceeding its internal temperature rise, keeping the output voltage within regulation. Molded construction in the 2917 case means the capacitor body is encapsulated, not conformally coated — the part stands up to board wash and conformal coat processes without solvent ingress into the dielectric.
Temperature grade — where this part fits
The ±10% tolerance is the standard production grade; if your BOM calls for tighter binning, the same series offers ±5% selection — confirm the part marking before assembly.
This part can be designed into a new BOM today without planning a future substitution. A formal quote is issued before any commitment.
