Frequently Asked Questions
What is the capacitance and ESR of the TMCMB0G337MTRF and at what frequency is ESR measured?
The TMCMB0G337MTRF has a capacitance of 330 µF and an ESR of 1100 mΩ, both measured at 100 kHz. This frequency-specific ESR rating is important for switching power supply designers, as it directly determines the ripple current handling capability and output voltage ripple at typical converter switching frequencies between 100 kHz and 500 kHz.
Why is a solid tantalum capacitor like the TMCMB0G337MTRF preferred over aluminum electrolytic in compact power designs?
Solid tantalum capacitors such as the TMCMB0G337MTRF offer significantly longer operational life than aluminum electrolytic types because they contain no liquid electrolyte that can evaporate or degrade over time. At 330 µF in a 1.9 mm height profile, the TMCMB0G337MTRF provides more stable capacitance over the operating temperature range of -55°C to +85°C. Aluminum electrolytics of the same capacitance would typically be taller and less stable at high frequencies, making the solid tantalum preferable in compact and long-life applications.
How does the TMCMB0G337MTRF perform in high-ripple switching regulator output filter stages?
The TMCMB0G337MTRF is optimized for ripple current filtering with its ESR and ripple current specifications measured at 100 kHz, aligning well with typical switching regulator frequencies. The 330 µF capacitance combined with the 1100 mΩ ESR means that at 100 mA of ripple current, the voltage drop across the ESR is approximately 110 mV, which is acceptable for most 3.3 V and 5 V output rails. Stacking two or more of these capacitors in parallel further reduces effective ESR for demanding low-ripple applications.
