Key Features

• High‑Temperature Operation Rated for continuous operation up to +135 °C with endurance specified at 2000 hours at 135 °C.
• Robust Low‑Temperature Performance Includes ESR specification measured after testing at −40 °C to ensure low‑temperature behavior is characterized.
• Electrical Characteristics 3.3 mF capacitance at 25 V with ±20% tolerance and polarization suitable for DC decoupling and energy storage.
• Low ESR Equivalent series resistance specified as 35 mΩ at 100 kHz, supporting stable performance in high‑frequency circuits.
• Ripple Current Ratings Rated ripple current of 1.1 A at 120 Hz and 2.2 A at 10 kHz for handling AC ripple and transient currents.
• Surface‑Mount Can Package Radial, can‑style SMD package designed for automatic mounting machines and tape‑fed assembly; surface‑mount land size provided.
• Automotive Reliability AEC‑Q200 qualification and RoHS compliance for use in regulated and automotive program environments.

Typical Applications

• Automotive electronic modules — Bulk decoupling and smoothing in control units and power electronics where +135 °C operation and AEC‑Q200 qualification are required.
• Power supply filtering — DC link and output filtering in compact SMD power supplies that require defined ripple handling and low ESR at high frequencies.
• Industrial controls — Energy storage and noise suppression in factory automation and motor control electronics exposed to elevated ambient temperatures.
• Harsh‑environment electronics — Any compact, tape‑fed surface‑mount assembly needing capacitors qualified for extended high‑temperature endurance and characterized low‑temperature ESR.
