PCH1C121MCL1GS

The PCH1C121MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor from Nichicon's PCH series. It combines low ESR and high ripple-current capability with a compact SMD package designed for surface-mount assembly.

Designed for demanding environments, this part offers a 120 µF capacitance at 16 V, AEC-Q200 qualification, and a long endurance rating of 4000 hours at 135°C—making it suitable for applications that require reliable power decoupling and energy smoothing under elevated temperature conditions.

Key Features

• Dielectric and Construction  Conductive polymer aluminum solid electrolytic design delivers stable capacitance and low impedance at high frequency.
• Electrical Characteristics  120 µF rated capacitance with ±20% tolerance (at 120 Hz, 20°C) and a rated voltage of 16 V.
• Low ESR & High Ripple Handling  36 mΩ ESR measured at 100 kHz and high ripple-current capability (900 mA at 100 kHz; 450 mA at 120 Hz) to support switching power stages.
• High-temperature Endurance  Life rating of 4000 hours at 135°C, with endurance limits defined for capacitance change, tan δ and ESR after testing.
• Automotive-Grade Qualification  AEC-Q200 qualified for designs requiring automotive-level reliability.
• Assembly Compatibility  Surface-mount, radial can (SMD) chip type compatible with lead-free reflow soldering up to a 260°C peak.
• Temperature Range  Operation from −55°C to +135°C to cover a wide range of thermal environments.
• Compact Footprint  Part dimensions L: 6 × D: 6.3 mm with recommended land size 6.6 × 6.6 mm for space-constrained layouts.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Automotive Electronics  Power rail decoupling and energy smoothing in engine control units and power modules where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC Converters  Output filtering and bulk capacitance for high-frequency converters that benefit from low ESR and high ripple-current capability.
• Industrial Power Supplies  Bulk and smoothing capacitor in industrial power systems exposed to elevated ambient temperatures and continuous duty.
• Motor Control & Drive Electronics  Filtering and energy buffering in motor drivers and inverter modules where stable performance at high ripple currents is needed.

Unique Advantages

• High-temperature reliability: 4000 hours at 135°C provides predictable long-term behavior in hot operating environments.
• Lower loss, higher efficiency: 36 mΩ ESR at 100 kHz reduces conduction losses and helps maintain regulator stability at high switching frequencies.
• Robust ripple handling: 900 mA at 100 kHz and 450 mA at 120 Hz support demanding power stages and reduce the need for parallel parts.
• Automotive-grade assurance: AEC-Q200 qualification supports use in vehicle electronics and other demanding applications.
• Surface-mount, production-ready: SMD radial can form factor with 260°C peak lead-free reflow compatibility simplifies high-volume assembly.
• Space-efficient footprint: Compact 6 × 6.3 mm part size with a 6.6 × 6.6 mm recommended land pattern minimizes PCB area for dense designs.
