Polymer tantalum chip capacitors are available in Z case size
With a lower profile than standard V cases, the T55 series of vPolyTan surface mount polymer tantalum moulded chip capacitors are now available from Vishay in the Z case (EIA 7343-19) size.
The height is 0.1mm lower than devices in the standard V case (EIA 7343-20), to allow an increase in package density to enable the design of thinner end products. The T55 capacitor in Z case are optimised for power management, battery decoupling, and energy storage in computers, servers, network infrastructure equipment, solid-state drives, and wireless transceivers.
Compact J, P, A, B, T (low profile B), D, V, and Z case sizes, the T55 series capacitors feature a wide capacitance range of 3.3 to 680 microF over voltage ratings from 2.5 to 63V and a capacitance tolerance of ± 20 per cent.
The capacitors provide low ESR from 500 down to 7mOhm at +25 degrees C. This, explains Vishay, is a result of the polymer cathodes, which offer greatly enhanced performance over manganese dioxide devices. Capacitance values up to 1000 microF and ESR values down to 6 mOhm are in development, adds Vishay.
Operating over a temperature range of -55 °C to +105 degrees C, the capacitors offer ripple current rating up to 5.66A IRMS and provide low internal resistance for enhanced charge and discharge characteristics. Terminations are lead (Pb)-free terminations and the T55 series is RoHS-compliant and halogen-free. The devices are available with high volume automatic pick and place equipment and offer a Moisture Sensitivity Level (MSL) of 3.
Samples and production quantities of the T55 series capacitors in the Z case size are available now, with lead times of 12 to 14 weeks.
