Polymer construction gives it a rated ESR of 70 mΩ measured at 100 kHz, which is the critical figure for high-frequency decoupling on cores, PLLs, and sensitive analog rails where a bulk ceramic or electrolytic would add too much impedance at switching transients. ## Footprint, packaging, and what the ±20% tolerance means It ships on tape-and-reel for automated placement and also on cut tape for low-volume prototyping runs. The capacitance tolerance is ±20%, which is normal for polymer bulk capacitors and means the part is sized for hold-up and decoupling rather than precision filtering — you pick up the 68 µF nominal and absorb the spread across temperature and bias.","metaTitle":"4TPB68M Panasonic Capacitor 68µF 4V POSCAP","metaDescription":"Panasonic 4TPB68M POSCAP polymer capacitor 68µF 4V 70mΩ ESR -55°C~105°C surface mount 1411.
