GXC1V221MCQ1GS

The GXC1V221MCQ1GS is a surface-mount conductive-polymer hybrid aluminum electrolytic capacitor designed for high-reliability, high-temperature applications. It combines low ESR and high ripple-current capability with long life at elevated temperature to support demanding power-delivery functions.

Targeted use cases include automotive electronics and high-reliability power conversion where compact SMD packaging, stable performance up to 135°C, and AEC‑Q200 qualification are required.

Key Features

• Capacitance and voltage — 220 µF rated at 35 V with ±20% tolerance (measured at 20°C, 120 Hz).
• Low ESR — ESR of 16 mΩ at 100 kHz and 20°C, supporting efficient energy transfer and reduced thermal loss.
• High ripple-current capability — 495 mA at 120 Hz (low frequency) and 3.3 A at 100 kHz (high frequency) for demanding switching and filtering applications.
• High-temperature endurance — Qualified for 4000 hours at 135°C, providing long-term reliability under elevated operating temperatures.
• Dielectric loss (tan δ) — tanδ of 0.12 at 35 V (measured at 20°C, 120 Hz), indicating controlled dissipation factor for AC performance.
• Leakage current — Typical specified leakage current of 77 µA after standard charge conditions.
• Package and mounting — Surface-mount radial can (Chip type) with embossed carrier taping for automated assembly; size specified as φ10 × 10L (1.0 cm × 1.0 cm) and recommended land size 1.03 cm × 1.03 cm.
• Compliance and qualification — RoHS compliant and AEC‑Q200 rated for automotive-grade reliability.

Typical Applications

• Automotive power electronics — Bulk and decoupling capacitor for DC-DC converters, power rails, and ECU power conditioning where AEC‑Q200 qualification and 135°C endurance are required.
• On-board power modules — Output filtering and smoothing in compact power supplies and POL regulators benefiting from low ESR and high ripple-current handling.
• Telematics and infotainment — Energy storage and transient suppression in systems exposed to wide temperature ranges and stringent reliability demands.
• Industrial control — Filtering and energy buffering for motor drives, gate drivers, and power management in high-temperature environments.

Unique Advantages

• Thermally robust design: 4000-hour endurance at 135°C supports long-term operation in high-temperature environments.
• High ripple tolerance: Combined low-frequency and high-frequency ripple-current ratings (495 mA @120 Hz, 3.3 A @100 kHz) match modern switching regulator profiles.
• Low dissipation and losses: 16 mΩ ESR at 100 kHz and tanδ 0.12 (35 V) reduce power loss and heating in high-current circuits.
• Automotive-grade qualification: AEC‑Q200 rating aligns the capacitor with automotive reliability requirements for system designers.
• SMD-friendly packaging: Embossed carrier taping and chip-style can package simplify pick-and-place and reflow assembly flows.
• Regulatory compliance: RoHS conformity for use in regulated production environments.
