PCX1D121MCL6GS

The PCX1D121MCL6GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's PCX series. It provides 120 µF capacitance at a 20 V rating in a compact φ8×10 mm can-style SMD package designed for automated assembly.

Engineered for high-temperature environments and high ripple applications, this AEC-Q200-qualified, RoHS-compliant device targets automotive and industrial power electronics where low ESR, high ripple capability and long-term thermal endurance are required.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a rated voltage of 20 V and tolerance of −20% to +20%.
• Conductive-polymer construction — Solid electrolyte design for stable performance and long life under elevated temperature conditions.
• Low ESR — 29 mΩ equivalent series resistance measured at 100 kHz and 20 °C, enabling efficient high-frequency filtering and low loss.
• High ripple current capability — Supports 385 mA at 120 Hz (low frequency) and 770 mA at 100 kHz (high frequency), suitable for switching regulators and power-supply decoupling.
• Temperature & Endurance — Rated for −55 °C to +125 °C with a lifetime/endurance of 3000 hours at 125 °C.
• Leakage & dissipation — Specified leakage current of 480 µA and tangent of loss angle (tan δ) of 0.12 measured at 20 °C, 120 Hz, 20 V.
• Assembly-ready package — SMD radial can (φ8×10 mm) with embossed carrier taping and moisture-proof packing for pick-and-place processes; lead-free reflow capability to a 260 °C peak as specified for the series.
• Automotive-capable qualification — AEC-Q200 rating for designs requiring qualified components.
• Compliance — RoHS-compliant.

Typical Applications

• Automotive power electronics — Decoupling and smoothing in engine control units, power distribution modules, and other automotive systems where AEC-Q200 qualification and high-temperature endurance matter.
• Switching regulators and DC–DC converters — Low ESR and high ripple current support high-frequency switching applications for stable output and reduced heat generation.
• Industrial embedded systems — Power-supply filtering and bulk decoupling in applications operating across −55 °C to +125 °C.

Unique Advantages

• Robust high-temperature endurance: 3000 hours at 125 °C supports designs exposed to prolonged elevated temperatures.
• High-frequency performance: 29 mΩ ESR at 100 kHz and a 770 mA ripple current rating at 100 kHz enable effective filtering in fast-switching circuits.
• Automotive suitability: AEC-Q200 qualification supports use in automotive electronic assemblies that require component-level qualification.
• Surface-mount, assembly-ready form factor: Embossed carrier taping and moisture-proof packing simplify automated placement and handling.
• Solid polymer construction: Conductive-polymer electrolyte provides stable electrical characteristics and low loss across temperature.
