Key Features

• Core Construction Chip-type, low-impedance aluminum electrolytic design providing 1.1 mF (1100 μF) capacitance at 35 V with polarization.
• Electrical Performance Rated capacitance tolerance ±20% at 120 Hz/20 °C; leakage current after 2 minutes ≤ 0.01 CV or 3 μA (whichever is greater); specified tan δ (max.) 0.12 at 35 V (measurement frequency 120 Hz, 20 °C) with the datasheet note for larger capacitances.
• Ripple Current Capability Supports 710 mA at 120 Hz and 1.42 A at 10 kHz, enabling effective smoothing and decoupling in power circuits.
• Thermal and Reliability Ratings Operating temperature −55 °C to +105 °C with endurance specified as 5000 hours at 105 °C (capacitance change within ±30%, tan δ ≤ 200% of initial spec, leakage current ≤ initial spec).
• Package and Assembly Surface-mount radial can (SMD) package sized L: 1.35 × D: 1.25 cm, compatible with automatic mounting machines fed by carrier tape and marked with black print on the case top.
• Compliance AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated manufacturing and reliability requirements.
• Soldering and Shelf Performance Meets soldering heat resistance criteria (hot plate 250 °C for 30 s) and shelf-life recovery after 1000 hours at 105 °C when voltage-treated per JIS procedures.

Typical Applications

• Automotive Electronics — Suitable for automotive modules requiring AEC-Q200-qualified, high-temperature-capable SMD capacitance for power smoothing and decoupling.
• Power Supply Filtering — Used for bulk smoothing and ripple reduction in DC power rails where 35 V rating and elevated ripple current handling are required.
• High‑Reliability Industrial Controls — Fits surface-mount assemblies that demand long endurance at elevated temperatures (5000 hours at 105 °C) and controlled leakage characteristics.

Unique Advantages

• AEC-Q200 Qualification: Provides an industry-recognized reliability baseline for automotive and harsh-environment applications.
• High Temperature Endurance: Rated for 5000 hours at 105 °C, enabling longer service life in thermally demanding designs.
• Compact SMD Radial Can: Delivers 1.1 mF capacitance in a surface-mount radial-can footprint (L: 1.35 × D: 1.25 cm) compatible with automated tape-and-reel assembly.
• Measured Ripple Capability: Defined ripple current ratings at 120 Hz and 10 kHz help designers select the part for effective smoothing across low and high frequencies.
• Low Leakage and Loss Characteristics: Leakage current limited to 0.01 CV or 3 μA (after 2 minutes at 20 °C) and specified tan δ support predictable performance in precision and power circuits.
• Regulatory Compliance: RoHS conformity supports environmental compliance for production and procurement.
