What are the key features of EEE-HA1E100R?
- 10 µF at 25 V in a compact 5 mm SMD HA series package optimized for power supply decoupling and bulk energy storage on space-constrained PCBs
- Panasonic HA series low-profile surface-mount construction supports automated reflow soldering up to 260°C with high positional stability during assembly
- ±20% capacitance tolerance and wide operating temperature range ensure reliable performance in consumer and industrial power management circuits
What is EEE-HA1E100R used for?
The EEE-HA1E100R is commonly used in DC-DC converter output filters, linear regulator bypass networks, and microcontroller power supply decoupling where 10 µF bulk capacitance at 25 V provides effective low-frequency noise suppression. Its SMD format is ideal for space-constrained IoT modules, wearable electronics, and compact industrial sensors requiring stable voltage rails. The HA series construction also makes it suitable for audio equipment power rails and motor driver bias circuits where moderate ESR provides controlled damping.

Frequently Asked Questions
What capacitance and voltage rating does the Panasonic EEE-HA1E100R provide, and which supply rails does it suit?
The EEE-HA1E100R is rated at 10 µF capacitance and 25 V working voltage, making it suitable for decoupling supply rails from 3.3 V to 20 V with adequate derating margin. At 5 V and 12 V rails common in industrial controls and consumer electronics, the 25 V rating provides 2.5× to 5× voltage headroom, meeting industry standard 50% derating guidelines for long-term reliability.
How does the 5 mm footprint of EEE-HA1E100R compare to alternative SMD electrolytic capacitors of the same value?
The 5 mm diameter SMD footprint of the EEE-HA1E100R is one of the more compact form factors available for 10 µF at 25 V aluminum electrolytic capacitors; some competing parts use 6.3 mm or 8 mm diameter cans for the same electrical rating. Choosing the 5 mm package frees approximately 15 mm² to 35 mm² of PCB area per capacitor, a meaningful saving in high-density IoT module and wearable PCB designs.
For a 12 V to 5 V synchronous buck converter output filter, how many EEE-HA1E100R capacitors are recommended alongside ceramic decoupling caps?
A typical 5 V output filter uses 1 to 2 EEE-HA1E100R capacitors (10 µF each at 25 V) in parallel with 3 to 4 ceramic 100 nF capacitors to cover the full frequency range from below 10 kHz to above 10 MHz. The electrolytic 10 µF bulk capacitance handles low-frequency load transients of 100 mA to 500 mA, while the ceramics suppress high-frequency switching noise above 1 MHz.
Does the ±20% tolerance of EEE-HA1E100R affect its usability in timing or precision filter circuits?
Yes — ±20% tolerance means the actual capacitance can range from 8 µF to 12 µF, causing up to 20% deviation in RC time constants and filter corner frequencies. For precision timing circuits using RC networks at 1 kHz to 100 kHz, this tolerance is too loose; designers should use ±5% or ±10% film capacitors or C0G ceramics instead. The EEE-HA1E100R is best suited for bulk decoupling and energy storage where exact capacitance values are less critical.
