TDK B32021 Series Safety Capacitor, 3300pF, Y2 Class, 300VAC, 10mm Spacing

The TDK B32021 Series Safety Capacitor is an essential component designed to suppress electromagnetic interference (EMI) and enhance the safety of electrical and electronic equipment. It features a metallized polypropylene (PP) dielectric for stable performance and long-term reliability in demanding applications. Its Y2 suppression class rating ensures it is suitable for use where reinforced insulation is required, providing a critical safety barrier against electric shock and preventing mains-borne interference from affecting sensitive circuits.

This radial, box-style capacitor is rated for 300VAC and offers a dv/dt rating of 800V/µs, making it robust against high voltage transients. With a capacitance of 3300pF and a tolerance of ±20%, it provides consistent filtering performance. The through-hole mounting design and a standard 10mm lead spacing facilitate straightforward and secure installation on printed circuit boards (PCBs).

Engineered for a wide operating temperature range of -40°C to +110°C, this component is capable of functioning reliably in harsh environmental conditions. Its compact dimensions (15mm depth x 33mm width x 43mm height) make it a space-efficient solution for power supplies, motor drives, lighting ballasts, and various industrial control systems where safety and signal integrity are paramount.
