CD293 100V 10000µF Snap-In Aluminum Electrolytic Capacitor
The CD293 series is a high-capacity, heavy-duty aluminum electrolytic snap-in capacitor designed for high-density circuit layouts. With a massive 10000µF capacitance and a 100V voltage rating, it serves as an efficient bulk energy storage and ripple filtering component in power electronics. Its rigid snap-in pin terminals ensure a secure, vibration-resistant mount directly onto PCBs without external brackets.
- High Performance: Features an ultra-compact 35.5mm x 61.5mm footprint with high volumetric efficiency.
- Robust Thermal Envelope: Engineered for stable operation across a wide range of -40°C to +85°C.
- Safety Integrated: Built with a top pressure-relief vent to safely prevent explosion during overloads.
- Primary Uses: Ideal for switched-mode power supplies (SMPS), audio amplifiers, solar inverters, and industrial automation control systems.
