Key Features

• Electrical — Capacitance & Voltage: 820 µF rated capacitance with a 35 V working voltage and ±20% tolerance for predictable bulk energy storage.
• Low‑temperature ESR Specified: ESR specified after the −40 °C test, providing verifiable performance at low ambient temperatures; measured as 50 mΩ at 100 kHz.
• High ripple handling: Ripple current capability of 600 mA at 120 Hz and 1.2 A at 10 kHz for smoothing and filtering in switching power stages.
• Wide operating temperature: Rated from −40 °C to +135 °C to support elevated‑temperature boards and assemblies.
• Endurance at elevated temperature: Rated lifetime of 2000 hours at 135 °C, with endurance characteristics defined by the series specification.
• Surface‑mount package: Chip/radial can SMD package compatible with automatic mounting via carrier tape, simplifying high‑volume assembly.
• Reliability & compliance: AEC‑Q200 qualified and RoHS compliant, supporting regulated production and reliability expectations for automotive and industrial applications.
• Compact mechanical footprint: Case dimensions L: 1.65 cm × D: 1.6 cm with recommended land size L: 1.63 × W: 1.63 cm for space‑constrained layouts.

Typical Applications

• Automotive power electronics: Bulk filtering and supply decoupling in control modules where AEC‑Q200 qualification and high‑temperature tolerance are required.
• DC–DC converters and power supplies: Energy storage and ripple suppression for converters operating at elevated temperatures and high switching frequencies.
• Motor drive and inverter controls: Local decoupling and smoothing in systems that experience wide temperature swings and transient currents.
• Industrial and harsh‑environment electronics: Capacitor solution for embedded controllers and power modules that require long life at elevated temperature.

Unique Advantages

• High‑temperature endurance: 2000‑hour rated life at 135 °C enables sustained operation in hot environments without sacrificing capacitance performance.
• Verified low‑temperature ESR: ESR characterized after −40 °C testing and specified at 100 kHz (50 mΩ), reducing design uncertainty for cold‑start and low‑temperature operation.
• High ripple capability: Dual ripple ratings (120 Hz and 10 kHz) support both low‑frequency smoothing and high‑frequency switching applications.
• SMD‑friendly format: Chip/radial can SMD packaged for carrier‑tape automated placement, streamlining assembly on automated production lines.
• Qualified reliability: AEC‑Q200 qualification and RoHS compliance support regulated and long‑life product programs.
• Space‑efficient energy density: 820 µF in a compact footprint helps reduce board area while maintaining bulk storage capability.
