The T55 series of vPolyTan™ surface-mount polymer tantalum chip capacitors from Vishay offers low ESR values from 500 mΩ down to 12 mΩ.
The T55 series includes devices in the D case size, EIA 7343-31. Previously only found in larger case sizes, the single-digit ESR values of these new capacitors are as much as 5 mΩ lower than those typically found in devices housed in a D case.
The low ESR of the T55 capacitors results in a lower voltage drop, better frequency response, and high ripple-current ratings, cutting the number of capacitors required on the PCB.
The T55 series ranges in capacitance from 3.3 µF to 1,000 µF over voltage ratings from 2.5 V to 63 V. Supplied in case sizes ranging from an 0603 J case to a D case, the T55 features capacitance tolerance of ±20%. The capacitors are suitable for a wide range of functions, including:
