PCH1J390MCL1GS

The PCH1J390MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package. It delivers 39 µF at a 63 V rating with polarized construction and a compact footprint suited for dense power electronics.

Designed for high-temperature, high-reliability applications, this part provides low ESR and high ripple-current capability along with long-life performance up to 4000 hours at 135°C, making it appropriate for demanding embedded power subsystems and automotive electronics.

Key Features

• Capacitance & Voltage: 39 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-temperature range & long life: Operating temperature from −55°C to +135°C and endurance specified at 4000 hours at 135°C.
• Low ESR & high ripple current: ESR of 28 mΩ measured at 100 kHz, 20°C, with ripple current ratings of 950 mA at 120 Hz and 1.9 A at 100 kHz.
• SMD can package & land pattern: Chip-type radial can for surface-mount assembly with recommended land size 8.3 × 8.3 mm and compact dimensions (L: 1.0 × D: 0.8 cm).
• Reflow solder compatible: Lead-free reflow soldering conditions supported up to a 260°C peak for compatible reflow profiles.
• Reliability & compliance: AEC-Q200 qualified for high-reliability applications and RoHS compliant.

Typical Applications

• Automotive power electronics: Bulk and decoupling in modules that require AEC-Q200 qualification and extended high-temperature endurance up to 135°C.
• DC–DC converters and power rails: Output smoothing and transient support where low ESR (28 mΩ at 100 kHz) and high ripple-current capability reduce voltage ripple and thermal stress.
• Industrial control and drives: Filtering and energy storage in compact power assemblies exposed to wide temperature ranges and continuous high-load conditions.
• Telecom and networking power modules: Local bulk capacitance for converters and point-of-load stages that demand high ripple tolerance and small PCB area.

Unique Advantages

• High temperature endurance: Rated for 4000 hours at 135°C, enabling sustained operation where elevated case temperatures are expected.
• Low ESR at high frequency: 28 mΩ at 100 kHz reduces losses and heat generation in switching power topologies.
• Strong ripple handling: Specified ripple currents (950 mA at 120 Hz; 1.9 A at 100 kHz) allow reliable use on converter outputs and high-frequency decoupling.
• Automotive-grade qualification: AEC-Q200 qualification supports use in applications requiring validated reliability processes and testing.
• Surface-mount convenience: Chip can SMD format and defined land pattern (8.3 × 8.3 mm) simplify PCB integration and assembly with lead-free reflow profiles.
