◆ Product Advantages
- Deeply Optimized for IGBT Snubber Protection Circuits: Product material selection, structural design, and electrical parameters are comprehensively optimized for IGBT snubber circuits, effectively absorbing voltage spikes and high-frequency oscillations generated during high-speed IGBT switching, fundamentally protecting IGBT power devices from over-voltage breakdown damage and maximizing power module service life
- Ultra-Low Loss with Extremely Small Internal Temperature Rise: Extremely low dielectric dissipation factor (tanδ) results in very limited internal temperature rise even under continuous high-voltage high-frequency pulse circuit operating conditions, effectively preventing electrical performance degradation and insulation failure caused by heat accumulation, ensuring long-term reliable operation in densely packed power modules
- Excellent Flame Retardancy for Intrinsic Safety: Housing and encapsulation materials use high-grade flame-retardant materials meeting UL94-V0 flame retardancy standards, not supporting combustion or flame propagation under abnormal conditions, significantly enhancing the passive safety of the overall system
- Outstanding High-Frequency Characteristics with Lasting Stable Snubbing Effect: Extremely low equivalent series inductance (ESL) ensures excellent snubber characteristics are maintained across a wide frequency range from power frequency to high frequency, without degradation of snubbing effect as operating frequency increases
- Comprehensive Compatibility with High-Voltage High-Frequency Applications: Voltage ratings cover high-voltage DC application ranges, compatible with the actual high DC voltage levels of mainstream IGBT power modules, with extensive application coverage
◆ Key Selling Points
- Maximizing IGBT Protection and Significantly Reducing Power Module Failure Rates: Voltage spikes are the primary cause of IGBT over-voltage failure; using this product effectively suppresses switching spike voltages within safe limits, significantly reducing IGBT field failure rates from over-voltage and greatly minimizing unplanned downtime and maintenance costs
- Compact Size Supporting High-Density Integration Within Modules: Refined structural design facilitates direct integration inside or immediately adjacent to IGBT modules with extremely short wiring, minimizing circuit parasitic parameters and achieving optimal snubbing effectiveness
- Excellent Batch Parameter Consistency for Large-Scale Automated Production: Strict manufacturing process control ensures high inter-batch consistency of key parameters including capacitance, ESR, and ESL, suitable for large-scale automated assembly and quality control
- Widely Certified by International Electrical Safety Standards: Product electrical safety performance meets IEC, UL, and other internationally authoritative standard requirements, directly applicable in end products exported to European, American, and other markets
