Frequently Asked Questions
What is the capacitance and voltage rating of the TAJS105K016RNJ tantalum capacitor?
The TAJS105K016RNJ provides 1µF nominal capacitance with a 16V voltage rating, covering typical digital supply rails of 3.3V, 5V, and 12V with comfortable voltage derating margin of at least 50%. The 10% tolerance (K suffix) gives a capacitance range of 0.9µF to 1.1µF across production lots.
What ESR value does the TAJS105K016RNJ exhibit at 100kHz and why does this matter for power supply decoupling?
The TAJS105K016RNJ has an ESR of 15Ω measured at 100kHz. While higher than ceramic capacitors, this predictable ESR helps provide controlled damping in tantalum decoupling networks, preventing resonance oscillation in power planes. Designers typically pair it with a low-ESR 100nF ceramic capacitor to cover both high-frequency and bulk decoupling requirements in digital ICs.
How does the TAJS105K016RNJ solid tantalum construction benefit long-term reliability compared to aluminum electrolytics?
The TAJS105K016RNJ uses a solid manganese dioxide electrolyte rather than a liquid electrolyte, which eliminates the risk of electrolyte evaporation or leakage over time. This gives solid tantalum capacitors a mean time between failures (MTBF) significantly longer than aluminum electrolytics, especially in environments cycling between -55°C and 85°C, making them preferred in telecom and aerospace PCB designs.
What is the package height of TAJS105K016RNJ and for which slim-form applications is it most suitable?
The TAJS105K016RNJ has a maximum body height of 1.2mm, which is among the lowest profiles available for solid tantalum capacitors of this capacitance and voltage class. This makes it an excellent choice for ultra-thin consumer electronics such as wearables, hearing aids, and low-profile SSD controller boards where total PCB stack height is constrained to under 5mm.
