Product Information
Product Introduction
The HMAA Series uses a soft-pack module format to support short-duration energy delivery, voltage hold-up, pulse-current buffering and repeated charge-discharge service. It is not selected by capacitance alone: the usable voltage swing, ESR loss, peak current, temperature, mounting method and service profile must be evaluated together.
As a module family, it reduces system-level assembly work but still requires verification of internal series architecture, balancing strategy, terminal current and enclosure clearances.
Fast energy responseSuitable for seconds-to-minutes support where high cycle frequency and rapid power delivery are important.
Defined integration pathElectrical, thermal and dimensional checks are organized around the controlled series datasheet and part-number drawing.
Configurable supplyVoltage, capacitance, terminals, dimensions, module configuration and labeling can be reviewed for project fit.
How the HMAA Series Stores and Delivers Energy
A supercapacitor stores electrostatic energy and releases it through the external circuit. Usable energy is determined by the voltage window rather than the nominal capacitance alone:
Usable energy: E = 1/2 × C × (Vstart2 - Vend2)
Use the minimum acceptable load voltage for Vend. Then include ESR loss, converter efficiency, ageing margin and temperature effects before finalizing capacitance.
Five Checks Before Choosing a Part Number
1. Voltage margin
Keep every cell or module within its published operating limit under steady state and transients.
2. Usable energy
Calculate energy across the real discharge window, not from zero volts.
3. Current and ESR
Estimate initial voltage drop and I²R heating at peak and repeated current.
4. Temperature
Check ambient, internal rise, charging limits and cold-start behaviour.
5. Mechanics
Approve envelope, terminals, polarity, retention, creepage and service access.
Series and Parallel Design
Series connection raises the system voltage but reduces effective capacitance and requires voltage sharing or balancing review. Parallel connection raises capacitance and current capability, while interconnect resistance and current sharing must remain controlled. For a series string of similar cells, use the most restrictive cell voltage and include transient and tolerance margin. LORIDA can review cell count, balancing approach, terminals and module packaging from the project duty cycle.
ESR, Voltage Drop and Thermal Rise
Equivalent series resistance creates an immediate voltage drop of approximately I × ESR and heat of approximately I² × ESR. Repetitive pulses can produce more temperature rise than a single discharge. Provide the pulse amplitude, duration, repetition interval and recharge profile so conductor size, terminal format and thermal path can be reviewed together.
Why This Construction Matters
The soft-pack module format influences terminal resistance, mounting method, vibration behaviour, heat transfer, polarity control and serviceability. Module construction can simplify assembly and reduce external interconnections, but the complete module current path and balancing architecture must match the load.
Best Fit for Buyers
The HMAA Series is intended for OEMs, power-system integrators, industrial-control suppliers and component distributors that need a traceable electrical window plus part-number-level mechanical verification. It supports early feasibility screening, sample validation, pilot production and controlled release.

Reliability and Validation Plan
The supplied datasheet defines temperature, load, storage and cycle-related checks for this series. Project approval should add the real duty cycle: maximum steady voltage, transient voltage, charge current, discharge current, pulse frequency, ambient profile, cooling conditions and expected service life. Samples should be measured before and after the agreed electrical and environmental test sequence.

Request an Engineering ReviewFrequently Asked Questions
How do I calculate the required capacitance?
Use the usable-energy equation with the real start and end voltages, then include load power, converter efficiency, ESR drop, temperature and ageing margin.
Can several devices be connected in series?
Yes, but the effective capacitance falls and voltage sharing must be reviewed. Use conservative per-device voltage limits and an appropriate balancing strategy.
What determines pulse-current capability?
ESR, terminal resistance, conductor design, pulse duration, repetition rate and thermal conditions all matter. Provide the complete waveform for review.
Can dimensions and terminals be customized?
Mechanical feasibility can be reviewed together with voltage, capacitance, temperature window, module configuration, labeling and order requirements.
What is needed before sample approval?
Confirm the part-number datasheet, controlled drawing, polarity, mounting, electrical duty cycle, environmental conditions and agreed validation plan.
