22UF 35V K (TMCT01) Radial Tantalum Capacitor

Product Description

Product Description

A radial tantalum capacitor is a compact, high-performance electrolytic capacitor designed for broad applications in electronics, characterized by its radial lead configuration-with two parallel metal leads extending from one end of the capacitor body, enabling straightforward through-hole mounting onto printed circuit boards (PCBs).
Constructed with a tantalum metal anode, a thin tantalum pentoxide dielectric layer formed via anodization, and a solid manganese dioxide or conductive polymer cathode, these capacitors deliver exceptional performance metrics that set them apart from other capacitor types. They boast high capacitance density (offering large capacitance values in a small footprint), low equivalent series resistance (ESR), and excellent stability across a wide temperature range (typically operating from -55°C to +125°C, with some industrial-grade variants supporting extended ranges). Additionally, they feature minimal leakage current and reliable long-term performance, making them ideal for circuits requiring consistent energy storage and voltage filtering.
Radial tantalum capacitors are widely integrated into consumer electronics (such as smartphones, laptops, and audio equipment), automotive electronics (engine control units, infotainment systems, and safety modules), industrial control systems, and telecommunications devices. They excel in applications like power supply filtering, signal coupling, timing circuits, and backup power retention-particularly in space-constrained designs where efficiency and reliability are critical.
Notably, their radial lead design simplifies automated assembly and soldering processes, while their robust solid-state construction eliminates the risk of electrolyte leakage common in liquid electrolytic capacitors. However, they require careful handling to avoid reverse voltage application, which can lead to catastrophic failure; proper circuit design with reverse polarity protection is recommended for optimal performance and longevity.
