PCH1K121MCL1GS

The PCH1K121MCL1GS is a chip-type conductive polymer aluminum solid electrolytic capacitor from Nichicon’s PCH series. It delivers 120 µF capacitance at a rated voltage of 80 V in a compact surface-mount can package designed for reflow assembly.

Designed for demanding thermal and power environments, this SMD capacitor offers low ESR (18 mΩ at 100 kHz), high ripple current capability, and a long life rating of 4000 hours at 135 °C. The part is AEC-Q200 qualified and RoHS compliant.

Key Features

• Capacitance & Voltage: 120 µF capacitance with an 80 V rated voltage, suitable for higher-voltage power rails.
• Low ESR & High Ripple Handling: ESR of 18 mΩ at 100 kHz and ripple current ratings of 2 A (100 kHz) and 1 A (120 Hz) for effective decoupling and smoothing under dynamic load.
• High-Temperature Endurance: Rated lifetime of 4000 hours at 135 °C and an operating range of −55 °C to +135 °C for sustained performance at elevated temperatures.
• SMD Package & Reflow Compatibility: Chip-type radial can SMD package (size L: 1.6 cm × D: 1.0 cm) compatible with lead-free reflow soldering conditions up to a 260 °C peak.
• Reliability & Qualification: AEC-Q200 qualified with specified endurance, damp heat, and shelf-life behaviors documented for predictable field performance.
• Polarized with Standard Tolerance: Polar capacitor with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power electronics: Stabilizing and smoothing power rails in automotive modules where AEC-Q200 qualification and high-temperature endurance are required.
• Industrial power supplies: High-voltage filtering and decoupling in converters and power modules that benefit from low ESR and 80 V rating.
• High-temperature electronics: Circuits that operate in elevated ambient temperatures, leveraging the 4000-hour life rating at 135 °C for extended reliability.
• Surface-mount assemblies: SMD designs that require a reflow-capable aluminum can capacitor compatible with lead-free soldering profiles.

Unique Advantages

• Wide voltage margin: 80 V rated voltage enables use on higher-voltage rails without sacrificing capacitance.
• Improved power handling: Low ESR (18 mΩ at 100 kHz) and high ripple current ratings reduce heating and improve filtering performance in power stages.
• Long-term high-temperature reliability: 4000 hours at 135 °C endurance rating supports designs exposed to sustained elevated temperatures.
• Automotive-grade qualification: AEC-Q200 qualification provides documented reliability criteria for vehicle electronics and other demanding applications.
• Reflow-ready SMD form factor: Surface-mount can package supports lead-free reflow up to 260 °C peak, simplifying modern PCB assembly flows.
• Regulatory compliance: RoHS conformity for use in regions requiring restricted substance compliance.
