PCA1E221MCL1GS

The PCA1E221MCL1GS is a chip‑type conductive polymer aluminum solid electrolytic capacitor designed for high‑reliability power applications. As part of the PCA series from Nichicon, it combines low ESR and high ripple‑current capability with a long thermal endurance profile to support demanding operating environments.

This SMD capacitor is suited to automotive and other electronics that require robust performance at elevated temperatures, offering a documented lifetime and AEC‑Q200 compliance for designs that target rugged, long‑life operation.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for stable electrical characteristics and improved ripple handling compared to conventional wet electrolytic types.
• Capacitance and voltage — 220 µF rated at 25 V with ±20% tolerance, suitable for decoupling and bulk storage on power rails.
• Low ESR — 20 mΩ specified at 100 kHz (20°C), enabling efficient high‑frequency performance and reduced power loss.
• High ripple current capability — Rated ripple current of 1.95 A at 120 Hz and 3.9 A at 100 kHz to support switching regulators and power conversion stages.
• Extended high‑temperature life — 4000 hours at 125°C endurance rating with defined post‑endurance limits for capacitance, ESR and leakage.
• Wide operating temperature range — −55°C to +125°C to cover a broad set of harsh operating conditions.
• Surface‑mount package and assembly — Chip SMD can (radial, can‑SMD style) with lead‑free reflow compatibility to 260°C peak for up to two reflow cycles.
• Automotive qualification and environmental compliance — AEC‑Q200 compliant and RoHS (2011/65/EU, (EU)2015/863) compliant.
• Compact footprint — Physical dimensions L: 1.0 × D: 0.8 cm with recommended land size L: 8.3 × W: 8.3 mm for PCB layout.

Typical Applications

• Automotive power electronics — Suited for DC‑DC converters, ECU power rails and other on‑board systems that demand sustained ripple handling and elevated temperature endurance.
• High‑reliability industrial electronics — Useful for power modules and embedded control systems where low ESR and long life at high temperature improve system robustness.
• Power supply decoupling — Effective at smoothing and transient suppression in switching regulator outputs and intermediate DC rails, thanks to high ripple ratings and low ESR.

Unique Advantages

• Low thermal loss: 20 mΩ ESR at 100 kHz reduces heat generation in high‑frequency applications, improving efficiency and thermal margin.
• High ripple endurance: Rated ripple currents (1.95 A at 120 Hz, 3.9 A at 100 kHz) allow sustained operation under switching loads without rapid degradation.
• Proven high‑temperature life: 4000 hours at 125°C provides a measurable lifetime metric for designs targeting long service intervals in hot environments.
• Automotive‑grade reliability: AEC‑Q200 compliance aligns the part with automotive design requirements for ruggedness and consistency.
• Assembly‑friendly SMD format: Lead‑free reflow compatibility to 260°C simplifies integration into modern surface‑mount manufacturing flows.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for commercial and automotive electronics.
