Frequently Asked Questions
What capacitance and voltage rating does the TAJS225K016RNJ provide?
The TAJS225K016RNJ offers 2.2 µF capacitance with a ±10% tolerance rated at 16 V DC, making it appropriate for decoupling 5 V to 15 V supply rails in portable electronics, IoT modules, and communication equipment requiring stable low-leakage filtering.
How does the 6000 mΩ ESR of TAJS225K016RNJ affect its suitability in switching regulators?
At 6000 mΩ ESR measured at 100 kHz, the TAJS225K016RNJ introduces relatively high series resistance, which limits its effectiveness as a low-ESR output filter in high-frequency switching regulators above 100 kHz; it is better suited for bulk decoupling or secondary filtering stages at lower frequencies.
What SMD case size does the TAJS225K016RNJ use and how does it fit on a PCB?
The TAJS225K016RNJ uses an EIA Case S (3216-12) SMD molded package measuring approximately 3.2 mm × 1.6 mm × 1.2 mm in height, compatible with standard SMT reflow soldering lines and suited for board areas with a footprint of roughly 5.12 mm².
When is TAJS225K016RNJ preferred over a ceramic capacitor of similar capacitance?
The TAJS225K016RNJ is preferred over ceramic alternatives when the circuit requires stable 2.2 µF capacitance under DC bias without the significant voltage coefficient derating seen in X5R or X7R ceramics, especially for bulk storage on 10 V to 15 V rails where ceramic parts lose 50% or more of their rated capacitance.
