PCL1C121MCL1GS

The PCL1C121MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD radial can package. It delivers 120 µF at 16 V with low equivalent series resistance and designed endurance for demanding thermal environments.

Targeted at automotive and other high-reliability electronics, this part combines long life, low ESR and high ripple-current capability to support power filtering and decoupling in compact surface-mount designs.

Key Features

• Capacitance & Voltage — 120 µF rated at 16 V with ±20% tolerance, suitable for bulk decoupling and energy storage in compact circuits.
• Low ESR — 27 mΩ ESR measured at 100 kHz, reducing losses and improving transient response in power stages.
• High Ripple Current — 2.9 A at 100 kHz (and 1.45 A at 120 Hz), enabling reliable performance under AC-loading in power conversion and smoothing applications.
• Long Endurance — Rated lifetime of 20,000 hours at 105 °C, supporting extended operation in elevated-temperature environments.
• Wide Temperature Range — Specified to operate from −55 °C to +105 °C, maintaining electrical characteristics across common automotive and industrial conditions.
• Surface-Mount Package — Radial can SMD package with physical dimensions L:7 × D:8 mm and recommended land size L:8.3 × W:8.3 mm for compact PCB layouts.
• Assembly Compatibility — SMD type compatible with lead‑free reflow soldering conditions up to a 260 °C peak.
• Standards & Compliance — AEC‑Q200 qualified and RoHS compliant, aligning with automotive and environmental requirements.
• Polarized Design — Polar capacitor for designs that require electrolytic polarity.

Typical Applications

• Automotive power electronics — AEC‑Q200 qualification and 20,000 h endurance at 105 °C make this capacitor suited for vehicle electronic control modules and power systems.
• Power supply filtering — Low ESR and high ripple-current capability support smoothing and decoupling in DC–DC converters and regulator outputs.
• Industrial and embedded systems — Wide temperature range and long life enable stable performance in compact, high-reliability assemblies.

Unique Advantages

• Extended thermal endurance: 20,000 hours at 105 °C gives designers predictable lifetime behavior in hot environments.
• Reduced conduction losses: 27 mΩ ESR at 100 kHz lowers I²R losses and improves efficiency in high-frequency power stages.
• High AC load capability: Ripple current ratings at both 120 Hz and 100 kHz support a range of switching and line-frequency applications.
• Surface-mount convenience: Compact radial can SMD footprint (7 × 8 mm) simplifies PCB layout for space-constrained designs.
• Automotive-grade qualification: AEC‑Q200 status and RoHS compliance streamline selection for regulated vehicle systems.
• Assembly-ready: Compatibility with lead‑free reflow profiles up to a 260 °C peak supports modern manufacturing processes.
