Key Features

• Construction: Conductive polymer hybrid aluminum electrolytic, chip type in a radial, can SMD package for automated surface‑mount assembly.
• High temperature endurance: Rated for operation from −55°C to 135°C with an endurance life of 4000 hours at 135°C when subjected to DC bias plus rated ripple current.
• Low ESR and high ripple capability: ESR of 20 mΩ (100 kHz, 20°C) and high frequency ripple current rating of 3 A at 100 kHz; low‑frequency ripple rating of 450 mA at 120 Hz.
• Electrical rating: 120 µF capacitance with ±20% tolerance and 50 V rated voltage; leakage current specified as ≤ 0.01CV (µA) after 2 minutes at 20°C.
• Reliability qualifications: AEC‑Q200 qualified and RoHS‑compliant (2011/65/EU, (EU)2015/863), with specified endurance, damp heat and soldering heat characteristics in the datasheet.
• Compact SMD footprint: Small package dimensions (L: 1 cm × D: 1 cm) and surface mount land size (L: 1.03 cm × W: 1.03 cm) for dense board layouts.

Typical Applications

• Automotive systems: Suitable for automotive electronics where AEC‑Q200 qualification and operation at elevated temperatures are required.
• High‑temperature power electronics: Use in power circuits and modules that demand stable capacitance, low ESR and sustained ripple handling at high ambient temperatures.
• Board‑level decoupling and filtering: Compact SMD can for local bulk filtering where long life and low impedance improve system stability and transient response.

Unique Advantages

• High thermal reliability: Endurance rated to 4000 hours at 135°C, enabling deployment in high‑temperature environments without sacrificing life expectancy.
• Low impedance at high frequency: 20 mΩ ESR at 100 kHz and 3 A ripple current capability help reduce voltage ripple and thermal stress in power rails.
• AEC‑Q200 qualification: Provides an established reliability baseline for automotive and other high‑reliability markets that require component qualification.
• Compact SMD package: Radial can SMD construction and small footprint facilitate space‑efficient board designs while supporting automated assembly.
• Documented endurance and environmental performance: Specified limits for capacitance change, tan δ, ESR and leakage after endurance, damp heat and soldering heat tests simplify design validation.
