Key Features
- 22 µF capacitance at 10 V in a compact 1206 (3.2 mm × 1.6 mm) SMT package, delivering high volumetric efficiency for space-constrained power rails
- 900 mΩ ESR measured at 100 kHz provides effective ripple current attenuation in switching power supply output filters
- MnO2 solid tantalum dielectric ensures stable capacitance over temperature and bias without the severe DC-bias derating typical of ceramic alternatives
- Ultra-low 1.6 mm profile compatible with slim consumer electronics and wearable device PCB stacks where component height is restricted to under 2 mm
Applications
The TPSA226K010R0900 is used in smartphone, tablet, and wearable device power management circuits where a stable 22 µF bulk capacitance is needed at 3.3 V to 5 V rails within a low-profile 1206 footprint. It is also deployed in portable medical instrumentation, handheld test equipment, and Bluetooth audio devices as an output decoupling capacitor for LDO regulators and DC-DC converters, where MnO2 solid tantalum construction provides reliable long-term capacitance stability without the DC-bias derating issues of X5R or X7R ceramic capacitors at equivalent voltage ratings.

Frequently Asked Questions
What is the ESR of TPSA226K010R0900 and at what frequency is it specified?
The TPSA226K010R0900 has an ESR of 900 mΩ measured at 100 kHz. For switching power supply output filters operating at typical frequencies of 100 kHz to 500 kHz, this ESR level determines the capacitor's contribution to output voltage ripple: at a 100 mA load transient, the initial voltage droop due to ESR alone is approximately 90 mV, which is acceptable for 5% tolerance rails in consumer electronics applications.
How does the TPSA226K010R0900 capacitance hold up over temperature compared to ceramic alternatives?
As a MnO2 solid tantalum capacitor, the TPSA226K010R0900 maintains its 22 µF capacitance within ±10% tolerance across its rated temperature range from -55°C to +125°C, with minimal dependence on DC bias voltage. By contrast, an X5R ceramic capacitor of equivalent 22 µF 10 V rating in an 0805 package can lose 70% to 80% of its capacitance at 10 V bias, delivering only 4 µF to 7 µF in circuit, making the tantalum a more predictable choice for bypass and bulk decoupling functions.
In which low-profile PCB designs is the 1.6 mm height of TPSA226K010R0900 a critical advantage?
The 1.6 mm maximum height of the TPSA226K010R0900 fits within the component height restrictions of smartwatches, true-wireless earbuds, and ultra-thin laptop PCBs where the total assembly height between board layers is limited to 2 mm or less. Standard cylindrical aluminum electrolytic capacitors with 22 µF at 10 V typically stand 5 mm to 7 mm tall, making them incompatible with these form factors and leaving the surface-mount tantalum as the only practical high-capacitance option within the height budget.
What ripple current rating should designers verify when using TPSA226K010R0900 as an LDO output capacitor?
Designers should verify the TPSA226K010R0900 ripple current rating against the LDO's specified minimum output capacitor ESR range. The 900 mΩ ESR at 100 kHz is higher than most ceramic alternatives, which can affect stability in LDO regulators that require output capacitor ESR below 200 mΩ for phase margin. For LDOs that are compatible with tantalum output capacitors, the typical ripple current rating for the TPS-A series at this value is approximately 100 mA RMS at 125°C ambient, confirming suitability for low-power LDO outputs supplying up to 500 mA loads.
