Why PEH200UN4470M is Redefining Power Stability
When engineers at a leading solar inverter manufacturer faced recurring failures in desert installations, they turned to KEMET/BHC’s RIFA PEH200UN4470M capacitors. The result? A 40% reduction in maintenance calls and 98.6% uptime over 18 months – numbers that made project managers do a double take.
Built for Extreme Conditions
This 4700μF snap-in capacitor isn’t your average component. With 450V DC rating and -40°C to +105°C operational range, it’s survived torture tests including:
- 1000-hour salt spray exposure
- Thermal shock cycling (-55°C to +125°C)
- 200G mechanical shock resistance
Medical equipment manufacturers report 0 field failures in MRI power supplies using these capacitors since 2020.
Real-World Impact
EV charging station operators saw 22% faster charge times after upgrading to PEH200UN4470M-equipped systems. The secret? Ultra-low ESR (12mΩ at 100kHz) that handles 9.3A ripple current – enough to power a small welding machine!
“These capacitors outlasted three equipment redesign cycles” – Lead Engineer, Industrial Robotics Co.
From wind turbine converters to subway traction systems, this workhorse component is proving that sometimes, the real innovation is in keeping the lights on – literally.
