PCH1C221MCL4GS

The PCH1C221MCL4GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in chip (can-SMD) format optimized for high-temperature, high-reliability applications. It combines low ESR and high ripple-current capability with a long rated life of 4000 hours at 135°C, making it suitable for demanding environments.

Designed for use where robust power decoupling and long-term thermal endurance are required, this part targets automotive and industrial designs that require AEC-Q200 qualification, lead‑free reflow compatibility, and stable performance across −55°C to +135°C.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance at a rated voltage of 16 V with ±20% tolerance.
• Conductive Polymer Solid Electrolyte — Solid polymer construction provides low ESR (23 mΩ at 100 kHz) and improved ripple-current capability for power supply smoothing.
• High Ripple Current — Supports 750 mA at 120 Hz (low frequency) and 1.5 A at 100 kHz (high frequency), enabling effective decoupling and bulk energy handling.
• Wide Temperature Range — Specified operating range from −55°C to +135°C for use in elevated-temperature environments.
• Long Life and Endurance — Rated for 4000 hours at 135°C; endurance, damp heat, and shelf-life behaviors are defined per the series specification.
• Surface-Mount Package — Compact chip-style can SMD with dimensions L: 8 mm × D: 6.3 mm and recommended land size 6.6 mm × 6.6 mm for PCB layout efficiency.
• Manufacturing Compatibility — Lead-free reflow capable with soldering profile support up to 260°C peak and defined resistance to soldering heat.
• Qualification — AEC-Q200 qualified for applications requiring automotive-grade component reliability.

Typical Applications

• Automotive Electronics — Use in modules where AEC-Q200 qualification, high-temperature endurance, and low ESR are required for stable power delivery.
• Power Supply Filtering — Bulk and decoupling capacitor for DC/DC converters and voltage-regulator modules, leveraging low ESR and high ripple-current ratings.
• High‑Temperature Industrial Electronics — Systems operating at elevated ambient temperatures benefit from the 4000‑hour life at 135°C and wide operating temperature range.

Unique Advantages

• Low ESR for Efficient Power Delivery: 23 mΩ at 100 kHz reduces voltage ripple and heat generation in power rails.
• High Ripple Handling: 1.5 A at 100 kHz and 750 mA at 120 Hz allow the capacitor to support transient currents and smoothing with confidence.
• Robust Thermal Endurance: Rated life of 4000 hours at 135°C ensures long-term reliability in high-temperature applications.
• Automotive-Grade Qualification: AEC-Q200 qualification supports use in automotive electronic subsystems that demand proven reliability.
• SMD Convenience with Reflow Compatibility: Chip-style can SMD package designed for lead-free reflow soldering (260°C peak) simplifies automated assembly.
