PCH1K390MCL1GS

The PCH1K390MCL1GS is a conductive polymer aluminum solid electrolytic SMD capacitor from Nichicon’s PCH series. It delivers a 39 µF capacitance at an 80 V rating in a compact surface-mount can package designed for high-voltage, high-temperature applications.

Targeted at demanding electronics where low ESR, high ripple handling and extended high-temperature life are required, this part is suitable for automotive electronics and other systems that require robust, long-lived SMD capacitance under elevated temperature and voltage stress.

Key Features

• Capacitance & Voltage — 39 µF rated capacitance at 80 V, with ±20% tolerance (measured at 120 Hz, 20°C).
• Low ESR & High Ripple Capability — Specified ESR of 35 mΩ at 100 kHz and ripple current ratings of 550 mA at 120 Hz and 1.1 A at 100 kHz for improved power-handling and lower losses in switching environments.
• High-Temperature Endurance — Long life rating of 4000 hours at 135°C; endurance and damp-heat specifications define limits for capacitance change, tan δ and ESR after stress.
• Wide Operating Temperature Range — Operates from −55°C to 135°C to cover harsh ambient conditions.
• SMD Package & Assembly — Surface-mount radial/can SMD package with dimensions L: 1.2 × D: 0.8 cm and recommended land pattern 8.3 × 8.3 mm; compatible with lead-free reflow soldering up to a 260°C peak.
• Reliability & Standards — AEC-Q200 qualified and RoHS compliant; leakage current, impedance ratio and ESR after endurance tests are specified in the datasheet.
• Polarized Design — Polarized capacitor suitable for DC circuit applications requiring electrolytic capacitance.

Typical Applications

• Automotive Electronics — Designed for automotive electrical systems where AEC-Q200 qualification and high-temperature endurance (4000 h at 135°C) are required.
• High‑Voltage SMD Power Rails — 80 V rating and low ESR make it suitable for compact surface-mount power stages and high-voltage DC bus decoupling.
• High-Temperature Power Modules — Long life at elevated temperature and specified ESR after endurance enable use in power electronics assemblies exposed to sustained heat.

Unique Advantages

• High-voltage capability: 80 V rating allows designers to use a single SMD capacitor for higher-voltage rail requirements, reducing part count.
• Low ESR with proven ripple handling: 35 mΩ (100 kHz) and up to 1.1 A ripple at 100 kHz support efficient operation in switch-mode and high-frequency environments.
• Extended high-temperature life: 4000 hours at 135°C provides predictable aging and reliability in heat-stressed designs.
• SMD reflow compatible: Lead-free reflow soldering up to 260°C peak supports standard surface-mount assembly processes.
• Automotive-grade qualification: AEC-Q200 qualification supports use in applications that demand automotive-level reliability.
• RoHS compliant: Conforms to RoHS directives for environmental and regulatory compliance.
