PCZ1D221MCL1GS

The PCZ1D221MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount can package, offering 220 µF capacitance at 20 V with ±20% tolerance. Designed for demanding thermal and power conditions, it targets automotive and other high-temperature electronics where long endurance, low ESR and strong ripple handling are required.

Key value comes from a combination of low equivalent series resistance, high ripple current capability and a wide operating temperature range (−55 °C to +150 °C), plus AEC-Q200 qualification and RoHS compliance for regulated and rugged designs.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 20 V with ±20% tolerance for bulk decoupling and energy storage needs.
• Low ESR — ESR of 33 mΩ measured at 20 °C and 100 kHz, delivering reduced loss and improved transient response in power circuits.
• High Ripple Current — Supports 700 mA at 120 Hz (low frequency) and 1.4 A at 100 kHz (high frequency), suitable for high-duty power conversion and switching applications.
• Wide Temperature & Long Life — Rated for −55 °C to +150 °C operation with endurance of 2000 hours at 150 °C, enabling use in elevated-temperature environments.
• Reliability & Qualification — AEC-Q200 rated and RoHS compliant, with datasheet-specified endurance and damp-heat performance criteria.
• SMD Can Package — Compact φ10 × 8 mm can (surface-mount) in embossed carrier taping with moisture-proof packing for automated assembly.
• Soldering Compatibility — Compatible with lead-free reflow conditions; peak capacitor surface temperature up to 260 °C (maximum two reflow cycles) as specified in the datasheet.
• Leakage Current — Typical leakage characterized in datasheet; example measurement listed as 132 µA for this part number under specified conditions.

Typical Applications

• Automotive Power Electronics — Bulk decoupling and energy buffering in DC–DC converters and vehicle power modules where AEC-Q200 qualification and high-temperature endurance are required.
• High-Temperature Electronics — Systems operating up to 150 °C benefit from the capacitor’s 2000-hour endurance at 150 °C and temperature-rated performance.
• Switch-Mode Power Supplies — Low ESR and high ripple-current capability support smoothing and transient handling in switching regulators and power stages.

Unique Advantages

• Thermal endurance for elevated environments: 2000 hours at 150 °C provides predictable lifetime performance in high-temperature applications.
• Improved power-stage efficiency: Low ESR (33 mΩ at 100 kHz) reduces conduction losses and heat generation in high-frequency circuits.
• Handles real-world ripple loads: Rated ripple currents of 700 mA (120 Hz) and 1.4 A (100 kHz) enable reliable operation in both low- and high-frequency domains.
• Qualification and compliance: AEC-Q200 rating and RoHS compliance simplify use in regulated industries and help meet supplier qualification needs.
• Surface-mount packaging for automated assembly: φ10 × 8 mm SMD can in embossed carrier taping and moisture-proof packing streamlines high-volume PCB assembly.
• Soldering robustness: Compatible with lead-free reflow up to 260 °C (per datasheet limits), supporting common SMT assembly processes.
