- Surface-mount A-case form factor (1.6 mm height) enabling automated reflow assembly on space-constrained PCB designs
What is TR3A226K6R3C1000 used for?
The TR3A226K6R3C1000 is used as an output bulk capacitor and rail decoupling element on 3.3 V and 5 V switch-mode power supply outputs where solid tantalum stability across temperature extremes is preferred over MLCC alternatives. Its 22 µF capacitance and 1000 mΩ ESR characteristic at 100 kHz are well matched to LDO regulator output stability requirements and point-of-load converter output filters in telecommunications base station cards and ruggedized embedded computing modules. The low-profile A-size molded package also suits portable medical instruments and industrial handheld devices where board height clearance is limited to under 2 mm.

Frequently Asked Questions
What is the ESR of the TR3A226K6R3C1000 and how does it affect DC-DC converter output ripple?
The TR3A226K6R3C1000 has an ESR of 1000 mΩ measured at 100 kHz. On a 500 kHz switching converter with 200 mA ripple current, this ESR contributes approximately 200 mV of ESR-induced output ripple, which is significant for low-noise analog supply rails. Designers targeting sub-50 mV ripple on 3.3 V rails should parallel this capacitor with an MLCC of 10 µF or greater to reduce effective ESR below 50 mΩ at the switching frequency.
Over what temperature range does the TR3A226K6R3C1000 maintain its 22 µF capacitance, and how stable is tantalum versus MLCC?
Solid tantalum capacitors like the TR3A226K6R3C1000 retain their rated 22 µF capacitance from -55°C to +125°C with minimal voltage-coefficient de-rating, typically within ±20% of the rated value across the full temperature range. Class II MLCCs (X5R, X7R) at 6.3 V can lose 50% to 80% of their nominal capacitance due to DC bias de-rating at the same voltage, meaning a 22 µF X5R MLCC at 6.3 V may only deliver 4 to 10 µF in-circuit. Tantalum is preferred wherever stable capacitance under DC bias and temperature is critical.
What voltage rating does the TR3A226K6R3C1000 carry, and what derating rule applies for 5 V rail use?
The TR3A226K6R3C1000 is rated at 6.3 V maximum working voltage. Industry standard practice for solid tantalum capacitors is to apply a 2× derating factor, meaning it should only be used on rails with a maximum DC operating voltage of 3.15 V or less in most applications. For a 5 V rail, a 10 V rated tantalum capacitor is the minimum safe choice. Exceeding the 50% derating guideline on tantalum capacitors significantly increases the risk of surge-current-induced breakdown and ignition failure.
Can the TR3A226K6R3C1000 directly replace a 22 µF aluminum electrolytic SMD capacitor in a 3.3 V LDO output filter?
In most cases, yes. A 22 µF tantalum A-case at 6.3 V is a direct functional replacement for a 22 µF aluminum electrolytic SMD capacitor at 6.3 V on a 3.3 V LDO output, provided the LDO's minimum ESR stability window accepts 1000 mΩ. Many LDO datasheets specify a recommended output capacitor ESR range of 100 mΩ to 10 Ω for stability, placing the TR3A226K6R3C1000 within the acceptable band. The tantalum part also offers a significantly smaller footprint and height (1.6 mm) compared to a typical D-case aluminum electrolytic at equivalent capacitance.
