HHXA250ARA560MF61G 概要
An aluminum-polymer hybrid capacitor is a type of aluminum electrolytic capacitor that combines a liquid electrolyte with a conductive polymer cathode system. This hybrid construction sits hierarchically between standard aluminum electrolytic capacitors (which use only liquid electrolyte) and pure polymer aluminum capacitors (which use only polymer). The result is a component that offers lower equivalent series resistance (ESR) and higher ripple-current handling than conventional aluminum electrolytic types, while delivering better endurance under high temperature and voltage stress than pure-polymer aluminum parts. Within the broader taxonomy: capacitor -> aluminum electrolytic capacitor -> polymer hybrid aluminum capacitor.
Key features of the HHXA250ARA560MF61G include a capacitance of 56 µF at 25 V rated voltage, a capacitance tolerance of ±20%, a maximum ESR of 50 mΩ at 100 kHz, and a rated ripple current of 900 mArms. The device is qualified for 4000 hours of load life at 125 °C and is supplied on embossed carrier tape for automated surface-mount assembly. AEC-Q200 automotive compliance is indicated on Chemi-Con's HXA series datasheet, making the part suitable for under-hood and chassis electronic modules.
The hybrid polymer cathode delivers a stable capacitance-versus-temperature characteristic across the -55 °C to +125 °C operating range, with ESR remaining low even at high frequencies. The combination of low ESR and high ripple capability makes the HHXA250ARA560MF61G particularly effective at suppressing high-frequency noise on DC power rails generated by switching converters.
Typical applications include automotive ECU power-rail decoupling, DC-DC converter output smoothing, point-of-load (POL) bypass for FPGAs and processors, industrial motor-drive bus capacitors, LED headlamp driver output filtering, and base-station / networking equipment power filtering. The SMD form factor supports reflow soldering and high-density PCB layouts.
When designing with this device, derate the ripple current according to ambient temperature using the published temperature-correction factor, and verify that the actual applied DC voltage stays below 25 V including any transient overshoot. Place the capacitor as close as practical to the load IC's supply pin to maximize high-frequency decoupling effectiveness.

主な用途
HHXA250ARA560MF61G の用途: 7 件s: Automotive ECU Power-Rail Decoupling, DC-DC Converter Output Smoothing, Point-of-Load Bypass for Processors / FPGAs, Industrial Motor-Drive Bus Capacitors, LED Headlamp Driver Output Filtering, Networking / Telecom Equipment Power Filtering, Solar Inverter / Energy Storage DC-Link Filtering.
Automotive ECU Power-Rail Decoupling
The HHXA250ARA560MF61G's 25 V rating, AEC-Q200 qualification, and 4000-hour endurance at 125 °C make it ideal for automotive ECU power-rail decoupling where 12 V battery feeds must be filtered down to clean rails for sensors and microcontrollers. Placed on the 12 V input side of an LDO or DC-DC converter feeding an ECU, the part's 50 mΩ ESR at 100 kHz attenuates switching ripple while its 900 mArms ripple-current rating absorbs the current spikes of cold-crank and load-dump events. Compared with conventional 25 V aluminum electrolytics, the hybrid polymer construction reduces ESR by roughly 10× in the same 6.3 × 5.8 mm case, enabling smaller PCB area at the same decoupling performance.

DC-DC Converter Output Smoothing
The HHXA250ARA560MF61G delivers 56 µF of bulk capacitance with only 50 mΩ ESR at 100 kHz, making it a strong output filter candidate for non-isolated DC-DC converters in the 3.3 V to 15 V output range. In a typical buck-converter output node, the cap absorbs the inductor ripple current and reduces output voltage ripple to within the load's tolerance. The 900 mArms ripple rating comfortably handles the ripple amplitude of a 3-5 A buck converter at moderate switching frequencies. The SMD-can form factor supports reflow soldering and high-density PCB layouts.
おすすめ
Point-of-Load Bypass for Processors / FPGAs
High-current processors and FPGAs require dense, low-impedance decoupling right at the supply pins, and the HHXA250ARA560MF61G fits that role at the bulk-cap tier. Placed between the DC-DC converter output and the POL regulator input, its 56 µF bulk handles transient load steps of several amps while the 50 mΩ ESR controls the high-frequency component of the transient response. The 6.3 × 5.8 mm Radial Can-SMD package occupies minimal board area and reflows cleanly alongside MLCCs.
おすすめ
Industrial Motor-Drive Bus Capacitors
Motor-drive inverters and servo amplifiers regenerate large switching transients on their DC bus, and the HHXA250ARA560MF61G is rated to absorb those transients at industrial ambient temperatures up to 125 °C. Its 25 V rating suits 24 V industrial bus rails, the hybrid polymer cathode provides stable capacitance across the full -55 °C to +125 °C range, and the 4000-hour endurance at 125 °C supports years of continuous-duty operation. SMD mounting enables compact PCB integration inside IPM-based motor drives.
おすすめ
LED Headlamp Driver Output Filtering
Automotive LED headlamp drivers require output capacitors that survive under-hood temperatures with low ESR to minimize LED current ripple and avoid flicker. The HHXA250ARA560MF61G's AEC-Q200 qualification, 125 °C endurance rating, and 50 mΩ ESR suit this role. In a typical boost-driver output stage, the cap filters switching ripple to <1% LED current ripple, while its 900 mArms rating absorbs the high-frequency component from the switching node. Compared to MLCC-only solutions, the hybrid aluminum polymer avoids the acoustic noise and capacitance-loss issues of Class-2 ceramics.
おすすめ
Networking / Telecom Equipment Power Filtering
Base-station and networking power supplies require bulk capacitance on 12 V and 24 V intermediate bus rails, where the HHXA250ARA560MF61G's 25 V rating and 900 mArms ripple handling fit cleanly. In a typical 48 V-to-12 V intermediate bus architecture, the cap sits on the 12 V rail feeding point-of-load regulators for line cards and SerDes. The hybrid polymer cathode maintains low ESR even after years of continuous 60-80 °C operation, extending service intervals versus conventional aluminum electrolytics.
おすすめ
Solar Inverter / Energy Storage DC-Link Filtering
Solar micro-inverters and energy-storage DC-DC stages operate on a high-voltage DC link, and the HHXA250ARA560MF61G serves as a secondary filter on the lower-voltage auxiliary rails (12 V, 24 V). Its 25 V rating, AEC-Q200 qualification (for harsh outdoor enclosures), and 4000-hour endurance at 125 °C make it a robust choice for outdoor-mounted power electronics. The hybrid polymer cathode reduces dry-out risk that plagues standard electrolytics in high-temperature outdoor applications.

設計ノート
Estimated: at full 900 mArms ripple current, internal self-heating is approximately I²·ESR = 0.9² × 0.05 = 40.5 mW per part - low enough that no heatsink is required. The real derating concern is ambient temperature: Chemi-Con's HXA datasheet derates ripple current to roughly 540 mArms at 105 °C ambient. Mount the cap away from hot components (FETs, magnetics) and verify the case temperature stays below 125 °C in your sealed enclosure with a thermocouple measurement.
Use Chemi-Con's recommended land pattern from the HXA-series datasheet; the 6.3 mm SMD-can needs slightly oversized pads versus a standard 6032 MLCC footprint to ensure reliable solder fillet formation. Place the cap within 5 mm of the load IC's supply pin to minimize high-frequency loop inductance. For DC-DC converter output filtering, pair this bulk cap with one or two 10 µF X7R 0805 MLCCs in parallel to handle the high-frequency component of the switching ripple above the polymer cap's ESR knee.
Critical: this part is polarized — reverse-mounting (anode and cathode swapped) will cause catastrophic failure within minutes of applying voltage, often with venting or rupture. Verify the cathode stripe orientation against the schematic before reflow. Also: do not exceed 25 V including transient overshoot; in 24 V industrial bus systems add a TVS or zener clamp to absorb load-dump transients above 28 V. Finally, do not substitute a standard 25 V aluminum electrolytic (e.g. EEEFP1E560P) thinking it is equivalent — ESR will be 5-10× higher and ripple handling much lower.
