Category
The C2831780 is a cost-effective axial lead aluminum electrolytic capacitor designed for 220uF energy storage in 25V DC systems. It features a wide operating temperature range (-40°C to +105°C) and provides basic filtering in power supplies, motor control, and audio equipment. While it offers good stock availability and RoHS compliance, engineers should verify ESR characteristics and ripple current limits for specific applications. The ±20% tolerance and lack of surface mount option limit its use in precision circuits, but its price-point and thermal performance make it suitable for non-critical filtering in consumer electronics and industrial power systems.
