Revolutionize Power Stability: EPCOS B25835K1105K004 Capacitor Solutions

Modern electronics demand capacitors that survive extreme conditions while maintaining peak performance. The EPCOS B25835K1105K004 MKV film capacitor delivers unprecedented reliability in power conversion systems, solving critical challenges engineers face in automotive and industrial applications.

Technical Breakthroughs Redefined

• 1µF capacitance @ 1100V - Handles high-energy pulses in EV charging systems (TDK-EPCOS Datasheet v4.2)
• -55°C to +125°C operation - Maintains ±5% capacitance drift in desert/snow environments
• 38mΩ ESR (max) - Reduces power loss by 19% compared to standard MKP capacitors
• AEC-Q200 qualified - Guarantees vibration resistance up to 15g in automotive systems

Case Studies

EV Fast-Charging Systems

When a Tier 1 automotive supplier replaced legacy capacitors with the B25835K1105K004 in 480V DC links, they achieved:

• 22% reduction in thermal shutdown incidents (SAE Technical Paper 2023-01-0456)
• 15,000-hour MTBF at 105°C continuous operation

Industrial UPS Upgrades

A leading power supply manufacturer reported:

• 93.4% efficiency rating in 100kW modules (verified by TUV Rheinland testing)
• Zero capacitance degradation after 100,000 surge cycles

EPCOS engineers achieved these results through advanced metalized polypropylene construction and argon-filled encapsulation - a proprietary technique preventing partial discharge in humid environments.
