PCH1V271MCL1GS

The PCH1V271MCL1GS is a surface-mount, conductive polymer aluminum solid electrolytic chip capacitor in Nichicon’s PCH series. It provides 270 µF capacitance at a 35 V rating in a compact φ10 × 10 mm SMD package and is polarized for DC applications.

Designed for demanding temperature and ripple environments, this part combines low ESR (20 mΩ at 100 kHz) and high ripple current capability with extended high-temperature endurance, making it well suited to automotive electronics and other high-reliability power systems.

Key Features

• Conductive polymer technology — Solid electrolyte construction for stable performance and improved ESR compared with conventional wet electrolytic devices.
• Capacitance and voltage — 270 µF nominal capacitance with a rated voltage of 35 V and tolerance of ±20% (–20% to +20%).
• Low ESR and high ripple handling — ESR of 20 mΩ at 20°C/100 kHz, with 1.1 A low-frequency ripple (120 Hz) and 2.2 A high-frequency ripple (100 kHz) specified.
• High-temperature endurance — Rated operating temperature range of −55°C to +135°C with a life/endurance specification of 4000 hours at 135°C.
• Reflow-capable SMD package — Chip-type, surface-mount radial can (φ10 × 10 mm) built for lead-free reflow soldering per series specifications.
• Electrical leakage and dissipation — Specified leakage current (283 µA) and low tangent of loss angle (tan δ = 0.08 at 20°C, 120 Hz) for predictable behavior in power rails.
• AEC-Q200 qualified and RoHS compliant — Suitable for designs that require AEC-Q200 qualification; meets RoHS requirements.
• Packaging — Supplied in embossed carrier taping with moisture-proof packing for automated assembly.

Typical Applications

• Automotive electronic modules — For power filtering and decoupling in control units where AEC-Q200 qualification and 135°C endurance are required.
• High-temperature power assemblies — Bulk smoothing and ripple suppression in boards that operate at elevated ambient temperatures up to 135°C.
• SMD power rails — Low ESR and high ripple current capability support DC‑DC converters and local decoupling on compact surface-mount assemblies.

Unique Advantages

• Extended high-temperature life: 4000 hours at 135°C provides predictable long-term capacitance and ESR performance in thermal-stressed designs.
• High ripple tolerance: 2.2 A at 100 kHz and 1.1 A at 120 Hz allow the capacitor to handle demanding switching and low-frequency ripple loads.
• Low ESR for improved efficiency: 20 mΩ ESR reduces power loss and heat generation on power rails, supporting tighter voltage regulation.
• Compact SMD form factor: φ10 × 10 mm chip package simplifies PCB layout and enables automated placement for volume production.
• Automotive-grade qualification: AEC-Q200 rating supports use in vehicle electronics where industry qualification is required.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing reduces handling risk and supports high-throughput assembly.
