Key Features

• Capacitance & Voltage — 2.2 mF rated capacitance at 35 V for bulk energy storage and decoupling in compact surface-mount form.
• Wide Operating Temperature — Rated for −40 °C to +135 °C to support circuits exposed to extended high-temperature conditions.
• Low-temperature ESR Specification — ESR specified at −40 °C to ensure predictable performance across the full operating temperature range; measured ESR: 35 mΩ at 100 kHz.
• Ripple Current Capability — Handles 1.1 A at 120 Hz and 2.2 A at 100 kHz, supporting high-frequency filtering and power-supply smoothing.
• Reliability & Lifetime — Endurance specified as 2000 hours at 135 °C with defined limits for capacitance change, tan δ and leakage current.
• Surface-Mount Can Package — Radial, can-style SMD package sized L: 2.15 × D: 1.8 cm with surface-mount land footprint L: 1.83 × W: 1.83 cm; compatible with carrier-tape automated mounting.
• Polarized Type — Polarized aluminum electrolytic construction for DC bulk capacitance applications.
• Environmental Compliance — RoHS-compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — AEC-Q200-qualified component for vehicle electronic modules and subsystems that require wide-temperature operation and long-term reliability.
• Power and energy filtering — Bulk decoupling, smoothing and ripple attenuation in power rails where high ripple current capability and defined ESR are needed.
• High-temperature electronics — Boards and modules that operate in elevated ambient temperatures up to +135 °C, benefiting from the capacitor’s rated endurance.
• Surface-mount assemblies — Automated SMT production lines using carrier tape feed that require can-style SMD capacitors to save board area while delivering high capacitance.

Unique Advantages

• Qualified for automotive-grade reliability — AEC-Q200 qualification provides documented assessment for use in automotive electronic designs.
• Wide temperature capability — Specified operation from −40 °C to +135 °C with endurance characterized at 135 °C supports deployment in harsh thermal environments.
• Predictable ESR across temperature — ESR specified including post −40 °C testing delivers consistent high-frequency behavior for designers tuning power-supply loops.
• High ripple handling — Stated ripple current ratings at 120 Hz and 100 kHz enable reliable performance for both low- and high-frequency filtering tasks.
• Automated assembly ready — Carrier-tape compatible packaging simplifies integration into automated SMT lines and high-volume production.
• Documentation-backed endurance — 2000-hour life at 135 °C with defined acceptance criteria for capacitance, tan δ and leakage current supports long-term reliability planning.
