GYF1H470MCQ1GS

The GYF1H470MCQ1GS is a surface-mount conductive polymer hybrid aluminum electrolytic capacitor designed for high-reliability power applications. It delivers 47 µF at 50 V in a compact φ6.3 × 7.7 mm SMD can, engineered for low ESR and elevated ripple handling.

Targeted for automotive and other demanding electronics, the part combines a wide operating temperature range (−55 °C to 125 °C), AEC-Q200 qualification, RoHS compliance and a 4000-hour endurance at 125 °C to support long-term, high-temperature operation.

Key Features

• Conductive polymer hybrid construction — Low ESR and high-frequency performance suitable for power decoupling and smoothing in compact designs.
• Capacitance and tolerance — 47 µF nominal with ±20% tolerance at 120 Hz, 20 °C for predictable filtering behavior.
• Rated voltage — 50 V rated voltage for mid-voltage power rails.
• Low ESR — 40 mΩ at 20 °C / 100 kHz, supporting efficient energy transfer and reduced heating under AC ripple.
• High ripple current capability — 210 mA at 120 Hz (low frequency) and 1.4 A at 100 kHz (high frequency) to handle switching and ripple loads.
• Leakage and endurance — Leakage current specified at 23.5 µA and rated for 4000 hours at 125 °C under DC bias plus rated ripple current.
• Temperature and reliability — Operating range −55 °C to 125 °C with AEC-Q200 qualification for reliability in harsh environments.
• Package and mounting — Surface-mount radial can (φ6.3 × 7.7 mm) supplied in embossed carrier taping for automated PCB assembly.
• Standards — RoHS compliant.

Typical Applications

• Battery management systems (BMS) — Provides high ripple handling and low ESR required for charge/discharge filtering and transient suppression in BMS modules.
• Automotive power electronics — Suited for decoupling and smoothing on 12 V/24 V rails and mid-voltage subsystems where high temperature endurance is required.
• DC–DC converters and point-of-load filtering — Low ESR and high-frequency ripple capability reduce voltage ripple and improve converter stability.

Unique Advantages

• Long high-temperature endurance: 4000 hours at 125 °C ensures sustained performance in elevated-temperature environments and extends service life.
• High ripple capability across frequencies: Rated ripple currents of 210 mA (120 Hz) and 1.4 A (100 kHz) support both low- and high-frequency switching applications.
• Low ESR for thermal and electrical efficiency: 40 mΩ ESR at 100 kHz reduces losses and self-heating under load, improving system efficiency.
• AEC-Q200 qualified: Formal qualification for automotive-grade reliability where required by system designers.
• Compact SMD can package: φ6.3 × 7.7 mm size and embossed carrier taping enable high-density PCB layouts and automated assembly.
• Predictable leakage behavior: Specified leakage current (23.5 µA) supports power-budgeting and standby application planning.
