Fountain Inn, South Carolina – AVX Corp. has added a new U case (EIA Metric 7361-43) to its TRM Professional Series multi-anode, ultralow-ESR tantalum capacitors, extending the range with several new ratings designed to address the demands of an ever-expanding scope of high-reliability automotive, military, medical, aerospace, and industrial applications. These volumetrically efficient surface-mount, J-lead capacitors are now available in U case, E case (EIA Metric 7343-43), and D case (EIA Metric 7343-31), meet the requirements of AEC-Q200. They offer a wide range of capacitance values and voltage ratings spanning 4.7 µF to 1,500µF and 2.5V to 50V and achieve twice the reliability of TPM Commercial Series tantalum capacitors, which also feature the new U case size.

The TRM Series has a base failure rate of 0.5% per 1,000 hours at 85ºC and rated voltage (VR) with 0.1O/V series impedance, in addition to a 25% lower DCL limit (0.0075CV), high volumetric efficiency, and ultralow ESR values as low as 18mO at 100kHz.

TRM Professional Series tantalum capacitors offer stable electrical performance, high resistance to the thermomechanical stresses associated with PCB assembly processes, and long-lifetime operation.

TRM Professional Series tantalum capacitors are tested to MIL-STD-202 requirements to ensure robust resistance against mechanical shock and vibration and are also tested for resistance against surge voltage, humidity, and biased humidity. The series is rated for operating temperatures spanning -55ºC to 125ºC, lead-free compatible, and RoHS compliant with pure tin termination, but also available with a tin/lead (SnPb) termination. TRM Professional Series capacitors are also pick-and-place ready, shipped on 7” or 13” reels with standard lead-times.
