APXE100ARA271MH70G Übersicht
A polymer aluminum capacitor is a polarized aluminum electrolytic capacitor whose cathode is a conductive polymer layer rather than a liquid electrolyte. This construction places it in the broader taxonomy of electrolytic capacitor -> aluminum capacitor -> aluminum polymer capacitor -> surface-mount aluminum polymer capacitor. The polymer cathode eliminates the wet-electrolyte failure modes that limit conventional aluminum electrolytics, yielding lower ESR, benign failure behavior, and longer life at high temperatures.
Key performance attributes include a typical ESR of 21mΩ at 100kHz, ripple current capability of 3220mArms at 105°C with 100kHz forced-air conditions, 2000-hour load-life rating (with the APXE series offering 15000 hours at 105°C for smaller-case variants), a 6.7mm can height, and ±20% capacitance tolerance at 20°C/120Hz. The 8×6.7mm SMD form factor lands on a typical 8.30×8.30mm or 10.30×10.30mm PCB land pattern, making it drop-in compatible with several industry-standard radial-can SMD polymer aluminum footprints.
Typical applications include output filtering and decoupling in DC-DC point-of-load converters, bulk hold-up capacitors for graphics and server processors, low-voltage rails in telecom base-station equipment, and any PCB location where low-ESR bulk capacitance is required at the smallest possible can size. The 3220mArms rating lets the device absorb the high-frequency ripple produced by switching regulators without overheating, preserving system efficiency and long-term reliability.
When designing with this part, derate the applied voltage to remain below the 10V rated maximum, keep the surface temperature under the published 105°C category, and ensure the PCB land pattern matches the can diameter (8mm) so the part self-aligns during reflow. This page consolidates distributor pricing, drop-in alternatives, and design considerations that supplement the manufacturer datasheet.

Typische Anwendungen
APXE100ARA271MH70G ist geeignet für 6 Anwendungs: DC-DC Point-of-Load Bulk Filtering, Server and Graphics Card Voltage-Rail Hold-Up, Telecom Base-Station Power Filtering, USB-PD and Fast-Charging Adapter Output Smoothing, Industrial PLC and Factory Automation 10V Rails, Automotive Infotainment 10V Domain Filtering.
DC-DC Point-of-Load Bulk Filtering
APXE100ARA271MH70G is well-suited as the bulk output capacitor of a 10V POL buck regulator feeding a processor or FPGA. Its 21mΩ ESR at 100kHz and 3220mArms ripple rating absorb the high-frequency ripple that switching regulators inject, while the 270µF capacitance reduces the amplitude of load-step transients before the ceramic output caps respond. The 8×6.7mm radial-can SMD lands on a typical 8.30×8.30mm PCB land pattern, fitting easily adjacent to an SO-8 or smaller POL footprint. Compared with a 10V/270µF liquid-aluminum SMD, APXE100ARA271MH70G runs roughly 15-20°C cooler at the same ripple, extending board life.

Server and Graphics Card Voltage-Rail Hold-Up
On graphics cards and AI accelerator boards, APXE100ARA271MH70G serves as a hold-up capacitor on a 10V intermediate bus, providing tens of milliseconds of energy storage during sudden load changes. The 3220mArms ripple rating and 21mΩ ESR support a high di/dt environment where bulk MLCCs alone cannot economically match the capacitance. The polymer-aluminum construction avoids the dry-out failure mode of liquid-aluminum parts during long-term 105°C operation near the GPU die. Compared with multi-MLCC stacks, a single APXE100ARA271MH70G occupies less board area and reduces BOM count.
Empfohlen
Telecom Base-Station Power Filtering
In 48V-to-10V intermediate bus converters for telecom base stations, APXE100ARA271MH70G provides the bulk capacitance between the bus converter and downstream POLs. The 21mΩ ESR keeps the 100kHz fundamental and its harmonics below the noise mask required for sensitive RF chains. Operating from -55°C to +105°C, it tolerates outdoor cabinet temperature swings, and the polymer cathode ensures long life under continuous 105°C operation. Compared with conventional aluminum electrolytics, APXE100ARA271MH70G has 5-10× lower ESR and roughly 3× longer endurance, reducing field-failure risk.
Empfohlen
USB-PD and Fast-Charging Adapter Output Smoothing
APXE100ARA271MH70G placed on the 10V output rail of a USB-PD or fast-charging adapter smooths the high-frequency ripple produced by the primary-side PFC and LLC stages. The 3220mArms rating easily handles the adapter's full-load ripple, while the 21mΩ ESR keeps output voltage ripple below USB-PD specification limits across all supported voltages. The radial-can SMD package reflows cleanly with standard lead-free profiles. Compared with aluminum electrolytics, APXE100ARA271MH70G has lower impedance at high frequency and a much smaller footprint per microfarad.

Industrial PLC and Factory Automation 10V Rails
APXE100ARA271MH70G is used on the 10V analog supply rail of industrial PLCs and factory-automation controllers, where it filters switching noise from nearby digital rails feeding analog I/O or sensor front-ends. The -55°C to +105°C operating range supports outdoor cabinet and unconditioned-shop-floor environments, and the polymer-aluminum construction resists the vibration and thermal-cycling stresses common in industrial equipment. The 21mΩ ESR attenuates the high-frequency components of the digital switching noise, protecting analog accuracy.
Empfohlen
Automotive Infotainment 10V Domain Filtering
Although APXE100ARA271MH70G itself is not AEC-Q200 qualified, the same APXE family is widely used in non-safety automotive applications such as infotainment head units and cluster displays where a 10V bulk filter is required. The 21mΩ ESR handles the high-frequency currents drawn by Class-D amplifier output stages and display timing controllers, while the polymer cathode resists the dry-out failure mode that affects liquid-aluminum parts under the hood. For AEC-Q200 automotive applications, designers should specify the Chemi-Con automotive-grade APXE variant directly.

Wichtigste Unterscheidungsmerkmale
- Highest ripple-current rating in 8×6.7mm polymer-aluminum class (vs. APXE6R3ARA221MF61G)
- Wider capacitance headroom at 10V (vs. APXE160ARA101MF80G)
- Lower voltage rating enables thinner dielectric and lower ESR (vs. EEH-ZA1E271V (Panasonic, 25V/270µF))
Designhinweise
Estimated: at the published 3220 mArms ripple current and 21 mΩ ESR, the APXE100ARA271MH70G dissipates approximately I²·R = (3.22)² × 0.021 ≈ 0.218 W. With a typical SMD-can thermal resistance of ~30°C/W to a 1 square inch copper pour, junction temperature rise is around 6.5°C above ambient - well below the 105°C category limit. Verify with thermocouple measurements in the actual board environment, since adjacent hot components (POL inductors, MOSFETs) can raise local ambient significantly.
Use a land pattern matching the 8.0mm can diameter - Chemi-Con's recommended pattern is 8.30×8.30mm with 2.0mm-wide anode and cathode pads. The land pattern must support both the can mechanical mount and the reflow-solder fillet. Place APXE100ARA271MH70G on the output side of the switching regulator within 5mm of the inductor to minimize high-frequency loop area; the 21mΩ ESR is sensitive to trace resistance in series with the cap.
Do not reverse-polarize APXE100ARA271MH70G - polymer aluminum capacitors fail short on reverse voltage. The cathode stripe on the can top and the shorter lead must connect to the lower-voltage side of the circuit. Also avoid exceeding 10V DC continuous: although the device tolerates brief transients above 10V (per Chemi-Con surge ratings), continuous operation above the rated voltage accelerates capacitance loss and ESR rise.
For high-frequency decoupling on a 10V rail, pair APXE100ARA271MH70G with one or more 22µF/16V MLCCs placed within 2mm of the load. The polymer aluminum handles the bulk charge storage and low-frequency filtering, while the MLCCs absorb the high-frequency load-step transients above the polymer cap's self-resonance. This hybrid bulk+MLCC layout is standard for POL regulators and significantly reduces output voltage ripple compared with either capacitor type alone.
