Frequently Asked Questions
Which low-voltage power rails is EEE-FK0J220R suited for, and what capacitance does it provide?
The EEE-FK0J220R provides 22 µF of capacitance rated at 6.3 V, making it well suited for filtering 3.3 V and 5 V power rails in microcontroller boards, IoT modules, and USB-powered devices. The 6.3 V rating provides a derating margin above the 5 V rail, and the 22 µF value supplies sufficient charge reservoir to suppress short-duration load transients at logic supply inputs without excessive board space.
How does the ±20% tolerance of EEE-FK0J220R affect bypass capacitor selection in low-voltage digital circuits?
For bypass and bulk filtering at 3.3 V or 5 V rails, a ±20% tolerance on 22 µF means the actual capacitance may range from 17.6 µF to 26.4 µF. In most digital power supply bypass applications this variation has negligible impact because the target capacitance is chosen conservatively to absorb transients across a broad range. Designs requiring precise RC time constants or exact cutoff frequencies below 1 kHz should consider a ±10% or film capacitor instead of this electrolytic.
What makes full reel packaging of EEE-FK0J220R advantageous for consumer electronics production, versus cut-tape alternatives?
Full reel packaging delivers the EEE-FK0J220R as a continuous tape suitable for uninterrupted pick-and-place machine feeding across long production runs. This eliminates the tape-splicing delays and mis-feed events associated with multiple shorter cut-tape segments, reducing downtime on SMT lines producing thousands of boards per shift. For high-volume consumer electronics manufacturing, full reel procurement also reduces per-unit material handling cost and minimizes the risk of running out of components mid-run.
