Vishay T55 and TR3 Series of Tantalum Capacitors Offer Developers Two Options for Integrating Capacitance Values to 1,000μF with Low ESR into System Designs

New Yorker Electronics has announced therelease of Vishay’s small case size tantalum capacitors that offer newlow resistance values. Vishay’s T55 and TR3 series of tantalum capacitors provide developers with two options for integrating capacitance with low equivalent series resistance into system designs.
The T55 series of vPolyTan(tm) surface-mount polymer tantalum chipcapacitors has recently been extended to include new devices in the Dcase size (EIA 7343-31). These new parts offer low ESR values from 9mΩdown to 7mΩ. Previously only found in larger case sizes, thesingle-digit ESR values of these new capacitors are as much as 5mΩlower than those typically found in devices housed in a D case. The low
ESR of these T55 capacitors results in a lower voltage drop, betterfrequency response, and higher ripple-current ratings up to 5.67Arms,cutting the number of capacitors required on the PCB.
The T55 series parts range in capacitance from 3.3μF to 1,000μF overvoltage ratings from 2.5V to 63V, with a capacitance tolerance of ±20%.The devices are optimized for power management, battery decoupling and
energy storage.
Vishay’s TR3 series of solid tantalum capacitors are available in the A,B, C, D, E and W case sizes. Offered with voltage ratings ranging from4V to 75V and with capacitance values from as low as 0.47μF to as highas 1,000μF, they feature ESR values as low as 45mΩ. Maximumripple-current handling capability at 100kHz spans the range from 0.1Ato 2.5A. In the C, D and E case size variants, the TR3 capacitors are100% surge-current tested.
The TR3 devices are intended to perform decoupling, smoothing, bulkenergy-storage and filtering functions in industrial, telecom, andconsumer applications. Vishay Sprague has the broadest range of tantalum
capacitors offered by any manufacturer with devices that also includeconformal coated and molded surface-mount styles, as well as both radialand axial through-hole products, covering a wide range of automotive, consumer, industrial and telecommunications as well as very high-performance applications.
