KEMET offers two series of high temperature tantalum surface mount capacitors, the T498 and the T499.

The T498 Series is a high temperature version of KEMET's solid tantalum chip family that offers optimal performance in applications with operating temperatures of up to 150°C. Advancements in materials and testing have allowed for the introduction of this series which delivers a reliability level of 0.5% per 1000 hours at rated voltage at rated temperature. This series is available in five standard EIA case sizes with RoHS Compliant / 100% matte tin finish lead terminations as standard. Other termination options include 90Sn/10Pb finishes and gold for conductive adhesive attachment processes. Capacitance values range from .47μF to 220μF, in voltage ratings from 4 to 50 volts.

T498 Features

  • 150°C Maximum temperature capability
  • Temperature/Voltage derating: 2/3 at 150°C
  • Self-healing mechanism
  • Capacitance: 0.47 to 220μF
  • Reliability: 0.5%/1000 Hrs. @ rated voltage @ rated temperature
  • 100% Accelerated steady state aging
  • 100% Surge current testing
  • EIA standard case size
  • Voltage: 6 to 50 VDC
  • RoHS Compliant versions available
  • Various termination options

The T499 Series extends the temperature range capability to +175°C. The difference between the T499 and the standard tantalum capacitor lies within its material set and design. These materials still contain no lead and are fully RoHS compliant. The standard finish on the lead frame is a matte tin plating over nickel, and the device is capable of the 260°C reflow profiles as defined in J-STD-020C. A gold or tin-lead finish is also available by changing the part number designation.

T499 Features

  • 175°C Maximum Temperature Capability
  • 100% accelerated steady state aging
  • Derating: 0.5 Vr at 175°C
  • 100% Surge current testing
  • Self-healing mechanism
  • EIA standard case size
  • Capacitance: 0.15 to 220μF
  • Voltage 6 to 50V
  • Various termination options
  • Pb-free/RoHS compliant versions available
