Frequently Asked Questions
What are the capacitance, voltage rating, and ESR of the Vishay TR3A685K016C1500?
The TR3A685K016C1500 provides 6.8 µF of capacitance at a 16 V rating with an ESR of 1500 mΩ measured at 100 kHz. These characteristics suit it for power rail decoupling and low-frequency output ripple filtering in portable electronics and industrial systems where a space-efficient tantalum capacitor is preferred over larger aluminum electrolytic types.
How does the solid tantalum dielectric in TR3A685K016C1500 compare to wet electrolytic capacitors for industrial applications?
Unlike wet aluminum electrolytic capacitors, the solid tantalum dielectric in TR3A685K016C1500 does not use liquid electrolyte, eliminating the risk of electrolyte evaporation or leakage over the device lifetime. This gives the TR3A685K016C1500 better long-term capacitance stability across a -55°C to +125°C temperature range and in vibration-prone environments, making it preferred for mission-critical industrial and aerospace power filtering designs at 16 V.
Why would a designer choose TR3A685K016C1500 for microprocessor power supply decoupling on a compact PCB?
For a 3.3 V or 5 V microprocessor power rail requiring 6.8 µF of local decoupling within a tight board area, the TR3A685K016C1500 offers a low 1.6 mm height and a compact SMD molded case footprint — smaller than equivalent aluminum electrolytic capacitors. Its solid tantalum construction maintains stable capacitance across load transients at 100 kHz switching frequencies, reducing processor supply noise and eliminating the capacitance derating issues common with ceramic alternatives at 16 V bias.
