PCF1C390MCL1GS

The PCF1C390MCL1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s PCF series. It provides 39 µF capacitance at a 16 V rating with low ESR and high ripple current capability for demanding electronic power applications.

Designed and qualified for automotive use (AEC-Q200), this SMD radial can package combines compact size (φ6.3 × 6L) with a wide operating temperature range (−55 °C to +105 °C) and a rated life of 2000 hours at 105 °C, offering a durable solution for power filtering and decoupling in harsh environments.

Key Features

• Capacitance and Voltage — 39 µF capacitance rated at 16 V with a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Low ESR — ESR of 31 mΩ measured at 20 °C / 100 kHz, reducing losses and improving transient response.
• High Ripple Current — Low-frequency ripple current 1.2 A (120 Hz) and high-frequency ripple current 2.4 A (100 kHz) to support switch-mode and pulsed power rails.
• Leakage and Dissipation — Leakage current specified at 125 µA; tangent of loss angle (tan δ) 0.12 at 20 °C / 120 Hz for predictable dissipation characteristics.
• Automotive Qualification & Reliability — AEC-Q200 qualified with a load life of 2000 hours at 105 °C; meets endurance and damp-heat criteria in the datasheet.
• Reflow & SMD Compatibility — SMD type compatible with lead-free reflow: peak 260 °C (single reflow at ≤260 °C; two reflows allowed at ≤250 °C per datasheet guidance).
• Packaging & Mounting — Radial can SMD package (φ6.3 × 6L) supplied in embossed carrier tape with moisture-proof packing; recommended land size 6.6 × 6.6 mm.
• Wide Temperature Range — Operating from −55 °C to +105 °C to accommodate a broad set of environmental conditions.
• RoHS Compliant — Conforms to RoHS directives.

Typical Applications

• Automotive Power Electronics — Filtering and decoupling on on-board power rails and power-supply modules where high ripple current and low ESR are required.
• Electronic Control Units (ECUs) — Bulk and decoupling capacitance in control modules that require AEC-Q200 qualification and robust thermal endurance.
• Infotainment and Telematics Modules — Power stabilization for audio, telematics and communications modules benefiting from low ESR and vibration-tolerant SMD packaging.

Unique Advantages

• Low-impedance performance: 31 mΩ ESR at 100 kHz minimizes voltage drop and heat generation in high-frequency switching applications.
• High ripple handling: 1.2 A (120 Hz) and 2.4 A (100 kHz) ripple ratings support both low- and high-frequency power stages without performance degradation.
• Automotive-grade reliability: AEC-Q200 qualification and 2000-hour life at 105 °C provide documented endurance for automotive electronics.
• Compact SMD can package: φ6.3 × 6L form factor and 6.6 × 6.6 mm recommended land size enable high-density PCB designs.
• Manufacturing-ready: Compatible with lead-free reflow processes (up to 260 °C peak per datasheet) and shipped in embossed carrier tape with moisture-proof packing for SMT lines.
• Predictable electrical behavior: Specified tan δ (0.12 at 20 °C / 120 Hz) and controlled leakage current allow straightforward thermal and loss budgeting.
