Frequently Asked Questions
What are the key electrical specifications of the TPSD226K025R0200 tantalum capacitor?
The TPSD226K025R0200 provides 22µF capacitance with a 25V voltage rating and 200mΩ ESR measured at 100kHz. The solid tantalum dielectric maintains stable capacitance over temperature and offers high volumetric efficiency compared to film or ceramic alternatives at this capacitance level.
How does the low ESR of TPSD226K025R0200 benefit switching power supply designs?
With an ESR of 200mΩ at 100kHz, the TPSD226K025R0200 dissipates less power during ripple current conduction, reducing self-heating and improving output voltage stability. This is critical in DC-DC converter output stages and point-of-load regulators where capacitor ESR directly affects loop stability and load transient response.
What PCB footprint and height does the TPSD226K025R0200 use?
The TPSD226K025R0200 uses the standard D-size SMD tantalum footprint with a height of 2.9mm, making it compatible with standard tantalum capacitor land patterns used in surface-mount assembly. Its compact profile supports automated pick-and-place assembly and fits within low-profile board stackups of 4mm or less.
When should TPSD226K025R0200 be chosen over aluminum electrolytic capacitors for the same application?
Solid tantalum capacitors like the TPSD226K025R0200 are preferred when long operational lifetime, consistent 22µF capacitance across -55°C to +125°C temperature range, and resistance to vibration are required. Unlike wet aluminum electrolytics, solid tantalum capacitors do not dry out over time, making them more suitable for industrial and avionics applications with 10-year or longer field life requirements.
