Tantalising tantalum

has introduced new TR3 series moulded tantalum chip capacitors that provide high efficiency with ESR values down to 0.035? and maximum ripple current values up to 2.07A

According to a statement, low ESR values allow for more efficient filtering in dc-to-dc conversion applications, while the devices ability to handle high currents is key in microprocessor bulk energy storage applications. The new Vishay Sprague TR3 capacitors are intended for applications in telecom, automotive, computer, industrial, commercial, medical, and avionics end systems.

In addition to providing very low ESR values and a high ripple current handling capability, the new tantalum capacitors feature a tantalum construction that is said to ensure long-term reliability.

TR3 devices are available in five moulded case sizes A, B, C, D, and E with 100 percent tin terminations (RoHS-compliant), or 90/10 Sn/Pb terminations upon request. Devices in the B, C, D, and E case sizes are 100 percent surge-current-tested. All TR3 capacitors meet EIA 535BAAE and IEC QC300801/US0001 specifications. The capacitors’ compatibility with high-volume pick-and-place equipment simplifies assembly.
