Frequently Asked Questions
What capacitance and voltage rating does the T491B224K050AT provide for power supply bulk decoupling?
The T491B224K050AT offers 220 µF capacitance rated at 50 V DC, with ±10% tolerance. This combination makes it effective for bulk decoupling on 24 V to 48 V power rails, holding up output voltage during load transients in DC-DC converter designs for industrial and telecom equipment.
How does MnO2 solid electrolyte in the T491B224K050AT benefit long-term reliability compared to wet tantalum?
MnO2 solid electrolyte in the T491B224K050AT eliminates the liquid electrolyte found in wet tantalum capacitors, removing the risk of electrolyte evaporation or leakage over time. This construction typically yields a lifetime exceeding 2000 hours at rated voltage and 85°C, making it suitable for industrial and telecom equipment with long service requirements.
Which case size is the T491B224K050AT and how does it affect PCB footprint selection?
The T491B224K050AT uses the EIA case B size, measuring approximately 3.5 mm × 2.8 mm. Designers should select a Kemet T491 case B land pattern for proper solder joint formation. This footprint is compatible with standard SMD tantalum pads and supports reflow soldering in pick-and-place production lines.
