Key Features

• Core Electrolytic Characteristics — 330 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C) and polarized construction for bulk energy storage and smoothing.
• Rated Voltage and Loss — Rated at 16 V DC with a maximum tan δ of 0.24 (measurement frequency: 120 Hz at 20°C).
• Temperature Range & Endurance — Operating range −40°C to +125°C with rated endurance of 2000 hours at 125°C when exposed to rated voltage.
• Low-Temperature Performance — Includes added ESR specification following the −40°C test; impedance stability characterized across the low-temperature range.
• Ripple Current Ratings — Specified ripple handling of 200 mA at 120 Hz and 400 mA at 10 kHz, enabling reliable AC ripple performance in power circuits.
• Leakage Current Spec — Leakage after one minute at 20°C not more than 0.03CV or 4 µA, whichever is greater, per series specifications.
• Package & Assembly — Radial, can-style SMD suitable for automatic mounting with carrier tape; compact dimensions L: 1 × D: 1 cm and recommended land pattern L: 1.03 × W: 1.03 cm.
• Qualification & Compliance — AEC-Q200 qualified and RoHS-compliant (2011/65/EU, (EU)2015/863) for regulated markets and safety-focused designs.
• Marking — Black print on the case top for clear identification.

Typical Applications

• Automotive Electronics — Bulk decoupling and smoothing in automotive control modules and power supplies where AEC-Q200 qualification and high-temperature endurance are required.
• Power Supply Modules — Energy storage and ripple suppression in DC‑DC converters and voltage regulators operating at elevated temperatures.
• Industrial Control — High-temperature industrial systems requiring reliable surface-mount capacitors for long-term operation.

Unique Advantages

• High-temperature endurance: Rated for continuous operation up to +125°C with 2000 hours endurance, reducing the need for over-spec’ing in hot environments.
• AEC-Q200 qualification: Provides an established reliability baseline for automotive and other safety-conscious applications.
• Low-temperature ESR consideration: ESR performance is specified after −40°C testing, helping designers account for cold-start and low-temperature behavior.
• Surface-mount automation ready: Carrier-tape compatibility and a compact SMD can form factor simplify pick-and-place assembly and reduce BOM complexity for automated lines.
• Defined electrical behavior: Clear specifications for leakage current, tan δ, and ripple current enable predictable design margins for power systems.
