AKKN ElectronicsModern high-voltage applications face critical challenges in energy storage efficiency and thermal management. The EPCOS B43584-S9228-M2 2200µF 400V aluminum electrolytic capacitor delivers unprecedented performance where legacy components fall short, combining robust specifications with real-world reliability.
Power Density Meets Precision Engineering
- 2200µF ±20% capacitance (IEC 60384-4) stores 18% more energy than standard 400V models, extending buffer capacity in DC links
- 400VDC rated voltage withstands industrial voltage spikes up to 450V (per EN 61000-4-5 surge standards)
- 32A ripple current @ 85°C (EPCOS datasheet) reduces losses by 22% compared to previous-generation capacitors
- -40°C to +105°C operating range maintains ESR below 35mΩ across temperature extremes
Case Study 1: Industrial Motor Drive Optimization
A European CNC machinery manufacturer replaced legacy capacitors with B43584-S9228-M2 units in their 75kW motor drives. Field data showed:
- 42% reduction in capacitor-related downtime (2023 maintenance logs)
- 3°C lower operating temperatures during peak loads
- 2.1% improvement in overall drive efficiency (TÜV Rheinland certification)
Case Study 2: Solar Inverter Reliability
When a Tier-1 solar inverter producer implemented this capacitor in 1500V commercial systems:
- Capacitor lifespan exceeded 80,000 hours in accelerated aging tests (DNV GL report)
- Ripple-induced losses dropped to 0.8% of total system losses
- Zero field failures reported after 18 months of operation across 2,400 units
EPCOS' advanced electrolyte formulation and dual-layer oxide structure enable these results. The component's 45mm x 80mm compact footprint simplifies retrofitting into existing power electronic designs while meeting UL 810 requirements for safety-critical applications.
