Frequently Asked Questions
What are the key electrical specifications of the EEE-HB1H3R3R?
The EEE-HB1H3R3R has a capacitance of 3.3µF with ±20% tolerance and a rated voltage of 50V DC. It belongs to Panasonic's HB series of aluminum electrolytic SMD capacitors, which are rated for operating temperatures up to 105°C and designed for long service life in power supply filtering and bypass applications.
Which power supply designs can use the EEE-HB1H3R3R as an output filter capacitor at 50V?
DC-DC buck converters, boost regulators, and flyback power supplies with output rails up to 50V can use this 3.3µF capacitor for output ripple filtering. In a typical 48V to 12V buck converter operating at 500 kHz switching frequency, a 3.3µF capacitor at the output reduces voltage ripple to under 50mV, meeting tight regulation requirements for industrial and telecom loads.
How does the SMD package of EEE-HB1H3R3R benefit automated PCB assembly?
The SMD (surface mount device) package of the EEE-HB1H3R3R eliminates through-hole drilling and allows automated pick-and-place machines to place components at rates exceeding 10,000 parts per hour. The bottom-terminal SMD footprint is also compatible with 260°C peak reflow soldering profiles, enabling lead-free assembly on both single-sided and double-sided PCBs without manual soldering.
What alternatives should I consider if the EEE-HB1H3R3R 3.3µF 50V is out of stock?
If the EEE-HB1H3R3R is unavailable, consider Panasonic's EEE-HA1H3R3R or EEV-HA1H3R3R in the same 3.3µF 50V SMD category, or cross-reference to Nichicon UMZ1H3R3MDD or Rubycon 50YXA3R3MEFCTA with equivalent 3.3µF capacitance, 50V rating, and ±20% tolerance. Always verify can diameter (typically 4mm or 5mm) and height to ensure dimensional compatibility with your PCB land pattern.
