Vishay Intros New TR3 Molded Tantalum Chip Capacitors
Vishay Intertechnology Inc. (Malvern, PA) introduced its new TR3 Series molded tantalum chip capacitors that provide high efficiency with ESR values down to 0.035 ?, and maximum ripple current values up to 2.07 A (100 kHz, 470 °F). 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 Vishay Sprague TR3 capacitors are intended for applications in telecom, automotive, computer, industrial, commercial, medical, and avionics end systems. In addition to providing low ESR values and a high ripple current handling capability, the new tantalum capacitors feature a proven solid-tantalum construction that ensures long-term reliability.
The TR3 devices are available in five molded 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. Capacitance values for the TR3 tantalum chip capacitors range from 0.47 °F to 680 °F, with standard capacitance tolerances of 10 percent and 20 percent. Voltage ratings range from 4 WVdc to 50 WVdc. The operating temperature range for the new devices is -55 °C to +85 °C, or +125 °C with voltage derating.
Samples and production quantities of the new TR3 molded tantalum chip capacitors are available now, with lead times of four to six weeks for larger orders. Pricing for US delivery in 10,000-piece quantities ranges from $0.08 to $1.00, depending on case size.
