PCR1K270MCL1GS

The PCR1K270MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in an SMD radial can package, offering a 27 µF capacitance at 80 V. Designed for high-reliability and high-voltage applications, it delivers low ESR and high ripple current in a compact footprint.

Its 4000-hour life at 125°C, AEC-Q200 qualification, wide operating range (−55°C to +125°C) and compatibility with lead‑free reflow soldering up to a 260°C peak make it well suited for demanding automotive and industrial power designs.

Key Features

• Dielectric and construction — Conductive polymer aluminum solid electrolytic design provides stable capacitance and low loss for high-frequency and power applications.
• Rated electricals — 27 µF capacitance with an 80 V rated voltage and ±20% tolerance for use in higher-voltage rails.
• Low ESR and high ripple handling — ESR of 38 mOhm at 100 kHz and ripple current ratings of 700 mA at 120 Hz and 1.4 A at 100 kHz support high-frequency decoupling and power-stage smoothing.
• High-temperature endurance — Long life: 4000 hours at 125°C with defined post-endurance characteristics (capacitance within ±20%, ESR ≤200% of initial).
• Wide operating range — Specified for −55°C to +125°C operation with controlled impedance ratios across temperature extremes.
• SMD radial can package — Compact size (L 1.0 × D 0.8 cm) and defined land size (8.3 × 8.3 mm) for surface-mount assembly and automated placement.
• Assembly and environmental compliance — Compatible with lead‑free reflow soldering (peak up to 260°C, two cycles maximum as specified) and RoHS compliant; AEC‑Q200 qualified.
• Polarized component — Designed for polarized circuit placement; observe correct orientation in assemblies.

Typical Applications

• Automotive power electronics — AEC‑Q200 qualification and 80 V rating make this capacitor suitable for power filtering and energy buffering in automotive control and power modules.
• DC‑DC converters and point‑of‑load — Low ESR (38 mOhm at 100 kHz) and high ripple capability (1.4 A at 100 kHz) support stable output filtering and fast transient response in converter designs.
• Industrial power supplies — High temperature endurance (4000 h at 125°C) and wide operating temperature range enable reliable smoothing and decoupling in harsh industrial environments.
• Motor drive and inverter systems — High voltage rating and robust ripple current handling suit power-stage decoupling and bulk buffering in motor controllers and inverter circuits.

Unique Advantages

• High-voltage capability in a compact SMD can — 80 V rating with a small L × D profile (1.0 × 0.8 cm) reduces board area while supporting higher-voltage rails.
• Low ESR for high-frequency performance — 38 mOhm at 100 kHz enables effective decoupling at switching frequencies, improving regulator stability and efficiency.
• High ripple current tolerance — Rated ripple of 700 mA (120 Hz) and 1.4 A (100 kHz) supports heavy AC stress typical in power conversion stages.
• Long-life high-temperature endurance — 4000 hours at 125°C with specified post-endurance limits provides predictable long-term behavior in elevated temperature applications.
• Automotive-grade qualification — AEC‑Q200 rating confirms suitability for designs that require recognized component qualification for automotive applications.
• Reflow-compatible SMD assembly — Compatible with lead‑free reflow up to 260°C (per datasheet profile), enabling modern surface-mount manufacturing flows.
