Core Technical Specifications Analysis

Superior Temperature Adaptability

The VMM series exhibits a wide operating temperature adaptability, offering differentiated support based on voltage specifications: ≤100V DC products operate within a temperature range of -55℃ to +105℃; 160-500V DC high-voltage products support operating environments from -40℃ to +105℃. This wide temperature range design ensures product reliability in various harsh environments, making it particularly suitable for automotive electronics and industrial applications.

Refined Electrical Parameter Configuration

This series offers a wide voltage range of 6.3-500V DC, with capacitance values ​​covering a wide range of needs from a few microfarads to thousands of microfarads. The products employ a standard capacitance tolerance of ±20% (at 25±2℃ and 120Hz), achieving an optimal balance between accuracy and cost. Excellent leakage current control: 6.3-100WV products ≤0.01CV or 3μA (whichever is greater), 160-500WV products ≤0.02CV+10(μA). This stringent leakage current standard ensures high-efficiency operation of the power supply system.
