Key Features

• High‑temperature rating – Specified operating temperature range from −40°C to +125°C to support systems exposed to elevated ambient temperatures.
• Long endurance at elevated temperature – Rated life of 5000 hours at +125°C for sustained high‑temperature operation.
• Electrical capacity – 100 µF capacitance with ±20% tolerance, suitable for bulk filtering and decoupling in high‑voltage circuits.
• Voltage and polarization – 100 V rated voltage; polarized electrolytic construction for energy storage and smoothing in DC circuits.
• Low impedance and ripple capability – Impedance of 250 mΩ with ripple current ratings of 663.3 mA at 120 Hz and 990 mA at 100 kHz for effective ripple handling.
• Automotive qualification and compliance – AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), aligning with automotive reliability and environmental requirements.
• Form factor and mounting – Radial lead mounting, can package with 5 mm lead spacing and compact dimensions (L: 2.0 cm × D: 1.25 cm) for through‑hole assembly.

Typical Applications

• Automotive power supplies – Bulk filtering and smoothing in vehicle DC power rails where components must tolerate high ambient temperatures.
• Engine control and powertrain electronics – Energy storage and ripple suppression in systems requiring robust, long‑life capacitors at elevated temperatures.
• In‑vehicle electronics modules – Decoupling and transient support in control modules and subsystems exposed to heavy‑duty service conditions.

Unique Advantages

• High‑temperature endurance: Rated for operation up to +125°C with a 5000‑hour life at that temperature, enabling reliable performance in hot environments.
• Automotive‑grade reliability: AEC‑Q200 qualification provides explicit validation for automotive electronics use cases that demand rigorous component qualification.
• Strong ripple handling: Specified ripple current at both low and high frequencies (663.3 mA at 120 Hz, 990 mA at 100 kHz) helps maintain performance in power conversion and filtering tasks.
• Compact radial can package: Small footprint (2.0 cm × 1.25 cm) with 5 mm lead spacing simplifies placement in through‑hole assemblies while delivering required capacitance and voltage rating.
• Regulatory compliance: RoHS compliance ensures the component meets current environmental substance restrictions.
