Product Description
The 2.2uF 350V Electrolytic Capacitor is a high-voltage passive component designed for precision filtering and start-up circuitry in power electronics. With a robust 350V rating, it is a critical element in the primary stages of small-scale Switch Mode Power Supplies (SMPS), LED drivers, and electronic ballasts where high DC bus voltages are present. Despite its small 2.2uF capacity, it excels at smoothing high-frequency voltage ripples and providing stable reference voltages in high-potential environments. Its 105°C thermal rating ensures high reliability and a long service life even when positioned near heat-generating components like power MOSFETs or high-wattage resistors.
Key Features
High Voltage Integrity: Engineered to operate safely on DC buses derived from 110V/220V AC rectification, handling up to 350V DC without dielectric breakdown.
105°C Thermal Tolerance: Designed to resist the "drying out" effect of electrolytes in high-heat environments, significantly extending the life of the parent device.
Miniature Radial Form Factor: The vertical through-hole design allows for a very small footprint on the PCB, ideal for compact power adapters and miniature drivers.
Safety Vent Integration: Features a pre-scored top-side safety vent designed to release internal gas pressure safely in the event of an electrical fault.
Consistent Frequency Response: Optimized for high-voltage DC filtering applications where stable capacitance is required across a wide operating temperature range
