Key Features

• Electrical Performance — 330 µF capacitance at 2.5 V with ±20% tolerance, providing bulk energy storage in low-voltage power rails.
• Low ESR — ESR specified at 7 mΩ (100 kHz, 20 °C), enabling improved transient response and reduced heat generation under high-frequency ripple.
• High Ripple Current — Rated ripple current of 2.8 A at 120 Hz and 5.6 A at 100 kHz for reliable operation in high-current switching environments.
• Temperature & Lifetime — Wide operating range (−55 °C to +105 °C) and load life of 2000 hours at 105 °C to support thermally demanding designs.
• Package & Mounting — Radial lead, can-type package (φ6.3 × 9L; lead spacing 2.5 mm) for through-hole assembly and wave/flow soldering compatibility.
• Compliance & Qualification — AEC-Q200 qualified and RoHS compliant with lead-free flow soldering condition correspondence for regulated and automotive environments.

Typical Applications

• Automotive power electronics — Bulk and decoupling capacitance on low-voltage rails where low ESR and high ripple handling improve regulator stability and heat performance.
• Control modules and ECUs — Energy buffering and transient suppression for control units operating across −55 °C to +105 °C.
• Power supply filtering — Smoothing and high-frequency filtering in compact, through-hole power assemblies that require robust ripple-current capability.

Unique Advantages

• Low-loss polymer electrolyte: The conductive polymer construction yields low ESR (7 mΩ at 100 kHz), improving efficiency and transient response in power rails.
