PCR1H390MCL1GS

The PCR1H390MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in an SMD can package from Nichicon's PCR series. It delivers 39 µF capacitance at a 50 V rating with low equivalent series resistance and high ripple-current capability for demanding assemblies.

Engineered for high-reliability and high-temperature operation, this part offers long endurance (4000 hours at 125°C), lead‑free reflow compatibility up to a 260°C peak, AEC-Q200 qualification, and RoHS compliance—making it suitable for automotive and other temperature‑challenging electronic applications.

Key Features

• Capacitance & Voltage — 39 µF nominal capacitance with ±20% tolerance at a 50 V rated voltage.
• Low ESR & High Ripple Handling — ESR specified at 45 mΩ (100 kHz, 20°C) with ripple current ratings of 1.3 A at 100 kHz and 650 mA at 120 Hz.
• High-Temperature Endurance — Rated for continuous operation from −55°C to +125°C and specified for 4000 hours at 125°C.
• Reliability & Qualification — AEC-Q200 qualified and designed to meet endurance and damp‑heat requirements; ESR after endurance is specified at −40°C per the datasheet.
• SMD Package & Reflow Compatible — Radial can SMD package (L: 7 × D: 8 mm) with lead‑free reflow soldering compatibility to a 260°C peak and a recommended land pattern of 8.3 × 8.3 mm.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — AEC-Q200 qualification and high-temperature endurance make this capacitor suitable for electronic modules used in automotive systems.
• High-temperature electronic assemblies — Long-life performance at 125°C and reflow compatibility support assemblies exposed to elevated operating or process temperatures.
• Compact SMD designs — Small radial can SMD package (7 × 8 mm) and a defined land pattern simplify board layout for space-constrained power and control boards.

Unique Advantages

• Long life at elevated temperature: 4000 hours at 125°C provides predictable endurance for thermal stress environments.
• Low ESR for improved ripple performance: 45 mΩ at 100 kHz and high-frequency ripple rating of 1.3 A help support stable power delivery in high-frequency applications.
• AEC-Q200 qualification: Qualification supports use in reliability-focused designs, particularly where automotive-grade components are required.
• Reflow process compatibility: Lead‑free reflow soldering to a 260°C peak (up to two passes at ≤260°C) eases integration into standard surface-mount assembly flows.
• RoHS compliance: Meets current RoHS requirements for material compliance and regulatory alignment.
