Frequently Asked Questions
What capacitance value and physical dimensions does EEEHAC221XAP offer for a through-hole power supply filter?
The EEEHAC221XAP provides 220 µF capacitance in a radial through-hole package measuring 6.3 mm in diameter and 7.7 mm in height. This compact size fits standard PCB lead spacing and is adequate for filtering low-frequency ripple in power supplies delivering currents up to several hundred milliamps.
How does the 0.0352 mA leakage current of EEEHAC221XAP affect a precision audio bias network?
A leakage current of 0.0352 mA through a 10 kΩ bias resistor introduces only 0.352 mV of offset voltage, which is negligible for most audio amplifier bias points operating at 5 V to 15 V. This low leakage makes EEEHAC221XAP suitable for coupling and filtering capacitors in audio circuits where excess DC offset can shift the amplifier operating point and increase distortion.
For a 220 µF bulk filter capacitor, how does EEEHAC221XAP compare to a similarly-sized solid polymer alternative?
Aluminum wet electrolytic capacitors like EEEHAC221XAP offer higher capacitance per unit volume than most solid polymer types at equivalent voltage ratings, but they have higher ESR (typically 0.5 Ω to 2 Ω at 100 Hz) and shorter lifetimes above +85°C. Solid polymer capacitors are preferred in high-ripple-current applications above 1 A or at operating temperatures exceeding +105°C, while the EEEHAC221XAP is the cost-effective choice for standard 220 µF filtering at moderate ripple currents.
Can EEEHAC221XAP be used in a signal coupling network between two 5 V audio stages, and what -3 dB cutoff frequency does it set with a 1 kΩ load?
Yes, EEEHAC221XAP is suitable for audio signal coupling at 5 V supply levels, as its rated voltage exceeds the signal levels present. With a 1 kΩ load impedance, a 220 µF coupling capacitor produces a high-pass -3 dB cutoff frequency of approximately 0.72 Hz (f = 1 / (2π × 1000 × 0.00022)), which is well below the 20 Hz audio band, ensuring flat coupling across the full audible frequency range.
