RS - High-performance tantalum capacitors satisfy diverse application needs

Published Mar 12 2010 [More Passives articles]
Latest from RS Components is the announcement of stock availability of Vishay's TR3 series moulded tantalum chip capacitors. They provide high efficiency with ESR values down to 0.035ohm and maximum ripple current values up to 2.07A (100 kHz, 470µF).

Low ESR values allow for more efficient filtering in DC-DC conversion applications, while the devices' ability to handle high currents is key in microprocessor bulk energy storage applications. The new 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 tantalum capacitors feature a proven solid tantalum construction that ensures long-term reliability. Outstanding stability over time and temperature further enhance the devices' performance and reliability.

Capacitance values for TR3 tantalum chip capacitors range from 4.7uF to 470uF with standard capacitance tolerances of ±10% and ±20%. Voltage ratings range from 4WVDC to 50WVDC. The operating temperature range for the new devices is -55C to +85C, or +125C with voltage derating, says the company.
