PCH1C471MCL1GS

The PCH1C471MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package, designed for high-capacitance applications that require extended high-temperature operation. It combines low equivalent series resistance (ESR) and high ripple-current capability with a long rated lifetime to support demanding electronic environments.

Typical use cases include electronics exposed to elevated temperatures and applications requiring robust power filtering and energy buffering. The part is AEC‑Q200 qualified and RoHS compliant, and is suitable for assemblies using lead‑free reflow soldering up to a 260°C peak.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 16 V for bulk decoupling and energy storage in compact SMD form.
• Low ESR — 22 mΩ equivalent series resistance measured at 100 kHz, enabling lower losses and improved voltage stability under load.
• High Ripple Current — 950 mA at 120 Hz and 1.9 A at 100 kHz, supporting high-frequency and power-dense applications.
• High‑Temperature Endurance — Rated for continuous operation from −55°C to +135°C with a specified lifetime of 4000 hours at 135°C.
• Reliability After Stress — Endurance and damp-heat specifications maintain capacitance within ±20%, tan δ and ESR within specified multipliers after test conditions; ESR is also specified after endurance at −40°C.
• SMD Package & Assembly — Chip-type SMD can with lead‑free reflow compatibility (peak up to 260°C), suitable for modern surface‑mount assembly processes.
• Industry Qualifications & Environmental — AEC‑Q200 qualified and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suited for vehicle electronics where AEC‑Q200 qualification and extended temperature range are required for power filtering and energy storage.
• High‑Temperature Power Modules — Provides bulk capacitance and ripple-current handling in modules and assemblies operating at elevated ambient temperatures up to 135°C.
• Industrial Electronics — Useful in rugged systems that demand long-term stability and low ESR under continuous thermal stress.

Unique Advantages

• Long High‑Temperature Life: 4000 hours at 135°C offers predictable aging characteristics for designs exposed to sustained heat.
• High Ripple Capability: 1.9 A at 100 kHz and 950 mA at 120 Hz enable stable operation in switching power and high-frequency circuits.
• Low Losses: 22 mΩ ESR at 100 kHz reduces I²R losses and improves efficiency in power delivery networks.
• Automotive‑Grade Qualification: AEC‑Q200 qualification supports use in applications requiring automotive component standards.
• Assembly Compatibility: Designed for lead‑free reflow soldering with a 260°C peak profile for modern PCB manufacturing flows.
• RoHS Compliant: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for restricted substances.
