Key Features

• Capacitance & Voltage: 33 µF rated capacitance at 63 V suitable for voltage rails requiring moderate energy storage.
• High Reliability Chip Type: Chip-type aluminum electrolytic design with AEC‑Q200 qualification and RoHS compliance for regulated production environments.
• Wide Operating Temperature: Rated for −40 °C to +125 °C to support operation across broad thermal ranges.
• Low-Temperature ESR Specification: ESR characterized after a −40 °C test and specified ESR of 800 mΩ at 100 kHz for predictable performance under cold conditions.
• Endurance at Elevated Temperature: 2000 hours at 125 °C endurance rating with defined limits for capacitance change, tan δ, and leakage current.
• Surface-Mount, Assembly-Ready Package: SMD radial can (φ6.3) with compact dimensions (7.7 × 6.3 mm) and compatible surface-mount land size (6.6 × 6.6 mm); suitable for automatic mounting with carrier tape.
• Ripple Current Capability: Specified ripple performance including 75 mA at 120 Hz and 150 mA at 10 kHz to support AC ripple handling across frequencies.
• Polarized Electrolytic: Polar construction for correct orientation in DC power circuits; capacitance tolerance ±20% at 120 Hz, 20 °C.

Typical Applications

• Automotive electronics: AEC‑Q200 qualification and −40 °C to +125 °C rating make this capacitor suitable for automotive control modules and power rails.
• Surface-mount assemblies: Designed for automatic mounting machines fed with carrier tape and a compact SMD can footprint for high-density board layouts.
• High-temperature operating environments: 2000 h endurance at 125 °C and specified low-temperature ESR support use where wide temperature stability is required.

Unique Advantages

• AEC‑Q200 Qualification: Provides documented high-reliability qualification for automotive-grade applications and designs requiring established component qualification.
• Low-Temperature ESR Characterization: ESR specified after −40 °C testing and known 800 mΩ value at 100 kHz enables designers to predict performance in cold-start or low-temperature conditions.
• Compact SMD Can Package: Small 7.7 × 6.3 mm can and 6.6 × 6.6 mm recommended land pattern help save PCB area while remaining compatible with automated assembly.
• Robust Thermal Endurance: 2000 hours at 125 °C endurance rating ensures stable capacitance, loss angle, and leakage performance after prolonged high-temperature exposure.
• Frequency-Aware Ripple Specs: Specified ripple currents at 120 Hz and 10 kHz provide clear guidance for handling AC ripple across low and high frequencies.
• Regulatory Compliance: RoHS compliance supports use in products subject to environmental directive requirements.
