Key Specifications

The B43509A2188M087 capacitor boasts several critical specifications that define its operational capabilities and suitability for various designs. The primary characteristic is its capacitance of 1800µF (microfarads) combined with a voltage rating of 200V DC. This significant capacitance value indicates its ability to store a substantial amount of electrical charge, crucial for smoothing rectified AC voltages in power supplies, providing ripple current filtering, and acting as a reservoir for sudden current demands. The 200V DC rating specifies the maximum continuous DC voltage that can be applied across the capacitor without causing dielectric breakdown, ensuring safe and stable operation in higher voltage circuits. Furthermore, its physical dimensions are 30mm in diameter and 55mm in length. This ‘large size’ form factor is typical for snap-in electrolytic capacitors designed for high-power applications, providing the necessary volume for the internal structure to achieve its high capacitance and voltage ratings while offering mechanical stability through its snap-in terminals for secure PCB mounting.
