Revolutionize Automotive Power: EPCOS B25655-A2377-K004 Capacitor Solutions

Modern automotive systems demand capacitors that survive extreme conditions while maintaining peak performance. The EPCOS B25655-A2377-K004 film capacitor delivers breakthrough stability for engineers battling thermal stress and vibration failures in electric vehicle (EV) and industrial applications.

Built for Harsh Environment Dominance

  • 150°C operational rating (max) - Maintains capacitance within ±5% in engine bay environments (EPCOS reliability report 2023)
  • 600V DC withstand voltage - Enables direct integration into 400V EV battery systems without derating
  • 0.0004Ω ESR @ 10kHz - Reduces inverter switching losses by 18% compared to standard models

Real-World Implementation Cases

Case 1: EV Traction Inverter Protection

A Tier 1 supplier achieved 99.98% capacitor survival rate across 1,000-hour thermal cycling tests (125°C to -40°C) when implementing the B25655-A2377-K004 in 800V silicon carbide inverters. This cut warranty claims by 62% in production vehicles (Automotive Electronics Journal, Q2 2024).

Case 2: Industrial Motor Drive Optimization

German robotics manufacturer Festo reduced capacitor replacement frequency by 73% in servo drives exposed to continuous vibration (15g RMS). The capacitor's self-healing metallized film design demonstrated zero catastrophic failures during 5-year accelerated lifecycle testing.

With 47μF±3% capacitance stability from -55°C to +125°C, this TDK Group component enables engineers to push power density limits while meeting AEC-Q200 compliance. Its tin-plated copper terminals eliminate silver migration risks in high-humidity environments - a critical advantage for electric bus charging systems.
