AVX has added new case sizes and codes in its series of ultralow-ESR tantalum capacitors, designed to address the demands of high-reliability automotive, military, medical, aerospace, and industrial applications.
These 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, offer a wide range of capacitance values and voltage ratings spanning 4.7–1,500µF and 2.5–50V.
The company has added a new “U” case (EIA Metric 7361-43) to its TRM Professional Series multianode, ultralow-ESR tantalum capacitors, extending the range with several new ratings.
The series claims a base failure rate of 0.5% per 1,000 hours at 85ºC and rated voltage (VR) with 0.1Ω/V series impedance, in addition to a 25% lower DCL limit (0.0075CV), high volumetric efficiency, and ultralow ESR values as low as 18mΩ at 100kHz.
These capacitors also exhibit stable electrical performance, high resistance to the thermomechanical stresses associated with PCB assembly processes, and long-lifetime operation.
Additionally, the “D” case variants feature a mirrored construction are said to effectively reduce ESR values by half and also results in lower ESL.
“These characteristics, plus AEC-Q200 qualification, makes TRM Series capacitors especially well suited for use in a wide range of power filtering and storage applications in harsh automotive and industrial environments”, AVX noted.
The capacitors are tested to MIL-STD-202 requirements to ensure robust resistance against mechanical shock and vibration, and are also thoroughly tested for resistance against surge voltage, humidity, and biased humidity.
Operating temperatures span -55ºC to +125ºC. The capacitors are lead-free compatible and RoHS compliant with pure tin termination, but is 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.
