Applications
The EEE-HC1C470P is used in DC-DC converter output bulk decoupling, microcontroller power supply bypass, and USB port power filtering on boards operating at 5 V to 12 V where 47 µF of capacitance is needed in a compact SMD footprint. Its tape-and-reel format and low ESR characteristics make it ideal for consumer electronics, networking equipment, and industrial control board production lines requiring consistent automated assembly and reliable voltage ripple suppression.

Frequently Asked Questions
How does the 47 µF capacitance and 16 V rating of the EEE-HC1C470P suit a 5 V USB power rail?
At 47 µF the EEE-HC1C470P stores sufficient charge to buffer load transients of tens of milliamperes on a 5 V USB power rail, and its 16 V rating provides a 3x safety margin above the 5 V operating voltage. The ±20% tolerance means capacitance ranges from 37.6 µF to 56.4 µF across the reel, which still satisfies typical bulk decoupling requirements for USB host controller supply pins consuming up to 500 mA.
In which frequency range does the EEE-HC1C470P provide effective ripple suppression for a DC-DC converter?
The EEE-HC1C470P's 47 µF aluminum electrolytic construction provides effective ripple suppression for switch-mode DC-DC converters operating at switching frequencies from 50 kHz to 500 kHz, where its bulk capacitance dominates the impedance response. At higher switching frequencies above 1 MHz, designers typically add a parallel 100 nF or 10 µF ceramic capacitor to compensate for the electrolytic's increasing ESR and inductive behavior beyond its self-resonant frequency.
What tolerance does the EEE-HC1C470P carry and when does that matter in a filter design?
The EEE-HC1C470P has a ±20% capacitance tolerance, meaning nominal 47 µF parts can range from 37.6 µF to 56.4 µF. In a bulk output filter where cut-off frequency is set by a 47 µF and 100 µH LC network, a -20% low-capacitance part shifts the resonant frequency from 2.3 kHz to 2.6 kHz — a shift that is generally tolerable for power supply ripple filtering but may require verification in audio-band precision supply designs.
How does the full tape-and-reel format of the EEE-HC1C470P benefit a contract manufacturer running high-volume SMT lines?
A full reel of EEE-HC1C470P capacitors contains a standard quantity (commonly 500 or 2000 pieces per reel depending on body size) that loads directly into SMT pick-and-place feeders without interruption. This eliminates the machine downtime of cut-tape reloads mid-run, reduces splicing errors that can cause placement voids, and enables unattended overnight production runs on boards requiring multiple 47 µF decoupling capacitors per unit.
