PCH1H390MCL4GS

The PCH1H390MCL4GS from Nichicon is a conductive polymer aluminum solid electrolytic chip capacitor in the PCH series, supplied in an SMD radial can package. It delivers 39 µF capacitance at a 50 V rating in a compact 8 × 6.3 mm footprint.

Engineered for high-temperature, high-reliability environments, this part combines low ESR (36 mΩ at 100 kHz), high ripple current capability (up to 900 mA at 100 kHz), long life (4000 hours at 135°C) and AEC-Q200 qualification, with lead‑free reflow compatibility to a 260°C peak.

Key Features

• Core Technology  Conductive polymer aluminum solid electrolyte in a chip-type SMD radial can, offering stable capacitance and low impedance.
• Electrical Performance  39 µF capacitance at 50 V with ESR of 36 mΩ measured at 100 kHz; ripple current ratings of 450 mA at 120 Hz and 900 mA at 100 kHz.
• High-Temperature Endurance  Rated for operation from -55°C to 135°C and specified for 4000 hours at 135°C under rated voltage.
• Reliability & Post-Endurance Behavior  Meets endurance criteria including capacitance change within ±20%, tan δ ≤150% of initial, and ESR ≤200% of initial after 4000 h at 135°C; ESR is also specified after endurance at -40°C.
• Package & Assembly  Compact L: 8 × D: 6.3 mm package with a recommended land size of 6.6 × 6.6 mm; compatible with lead‑free reflow soldering (peak up to 260°C, two reflows max under specified profile).
• Compliance & Qualification  AEC‑Q200 qualified and RoHS compliant, supporting use in regulated and qualification-sensitive designs.

Typical Applications

• Automotive Electronics  Suitable for automotive systems that require components qualified to AEC‑Q200 and rated for extended operation across -55°C to 135°C.
• Power Supply Decoupling  Low ESR and high ripple current capability make this capacitor suitable for bulk decoupling and smoothing in power rails.
• Power Conversion Modules  50 V rating and high ripple tolerance support use in DC‑DC converters and power regulation stages.
• High‑Temperature Electronics  Long life at 135°C and reflow compatibility enable reliable assembly and operation in elevated-temperature systems.

Unique Advantages

• High-Temperature Longevity: 4000 hours at 135°C provides extended operational life in heat-stressed environments.
• Low Losses and Thermal Stability: Low ESR (36 mΩ at 100 kHz) and controlled tan δ support efficient operation at high frequencies and temperature extremes.
• Robust Ripple Handling: Rated ripple currents up to 900 mA at 100 kHz reduce heating and improve reliability in high-switching-power applications.
• AEC‑Q200 Qualification: Explicit qualification supports integration into automotive and other qualification-driven systems.
• Surface-Mount Can in a Small Footprint: High capacitance in an 8 × 6.3 mm SMD can minimizes board area while retaining performance.
• Lead‑Free Reflow Compatibility: Meets lead‑free reflow soldering conditions (peak 260°C) for modern assembly processes.
