It provides 1.8 µF capacitance at a 400 V rating in a compact radial can SMD package suitable for environments requiring wide temperature tolerance and long-term stability.

Targeted use includes automotive and other demanding power electronics where AEC-Q200 qualification, wide operating temperature range, and endurance at elevated temperature are valued.

Key Features

• Capacitance & Voltage — 1.8 µF capacitance rated for 400 V, providing high-voltage energy storage in a small footprint.
• Wide Temperature Range — Specified operating temperature from −40 °C to 105 °C, supporting designs that encounter broad ambient conditions.
• AEC-Q200 Reliability — AEC-Q200 rating for component-level automotive-grade reliability and qualification for demanding applications.
• Endurance at High Temperature — Rated for 3000 hours at 105 °C under applied voltage (per datasheet endurance condition for 160–400 V range).
• Polarized, SMD Radial Can — Polarized aluminum electrolytic in a radial, can-style SMD package for board-level mounting versatility.
• Ripple Current Performance — Low-frequency ripple current 26 mA at 120 Hz and high-frequency ripple 43.42 mA at 10 kHz, useful for smoothing and decoupling in power circuits.
• Tolerance & Measurement Conditions — ±20% capacitance tolerance (specified at 120 Hz, 20 °C).
• Compact Footprint — Physical size L: 1.0 cm × D: 0.8 cm with recommended land pattern 8.3 mm × 8.3 mm to support compact board layouts.

Typical Applications

• Automotive Power Systems — Use in vehicle power electronics where AEC-Q200 qualification and -40 °C to 105 °C operation are required for stability and reliability.
• High‑Voltage DC Link and Filtering — 400 V rating and ripple current specs make the capacitor suitable for DC link smoothing and EMI/ripple suppression in high-voltage power stages.
• DC‑DC Converters — Compact SMD can package and high-voltage capability support use as input/output decoupling in isolated or non-isolated converters.
• Power Conditioning and Inrush Control — Long endurance at 105 °C and polarized construction suit roles that require sustained high-temperature operation and energy buffering.

Unique Advantages

• High Voltage Capability: 400 V rating enables use in high-voltage rails without additional series components.
• Automotive-Grade Qualification: AEC-Q200 rating supports integration into designs requiring component-level automotive qualification.
• Wide Operational Temperature: −40 °C to 105 °C range reduces need for thermal derating in many environments.
• Durable High‑Temperature Endurance: 3000 hours at 105 °C provides predictable long-term performance in elevated-temperature applications.
• Compact SMD Can Package: Small L×D footprint and defined land pattern (8.3 mm × 8.3 mm) simplify PCB layout for space-constrained designs.
• Measured Ripple Capability: Specified ripple current values at 120 Hz and 10 kHz allow designers to assess suitability for both low- and high-frequency filtering tasks.
