PCH1E271MCL1GS

The PCH1E271MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD radial-can package, designed for high-capacitance applications that require elevated temperature endurance. With a 270 µF capacitance at 25 V and low equivalent series resistance, it targets demanding power filtering and decoupling roles in automotive and industrial systems.

Key value comes from a combination of low ESR, high ripple-current handling and extended high-temperature life — including 4000 hours at 135°C — plus AEC‑Q200 qualification and RoHS compliance for regulated environments.

Key Features

• Dielectric and construction — Conductive polymer aluminum solid electrolytic, chip-type SMD in a radial can package for compact board-mounted bulk capacitance.
• Capacitance and voltage — 270 µF rated capacitance with ±20% tolerance and a 25 V rated voltage for mid-voltage power rails.
• Low ESR and high ripple handling — ESR of 19 mΩ (measured at 100 kHz) with ripple-current capability of 1.15 A at 120 Hz and 2.3 A at 100 kHz for effective decoupling and bulk filtering.
• High-temperature endurance — Rated operating range −55°C to +135°C and a specified lifetime of 4000 hours at 135°C, supporting designs exposed to elevated ambient or internal temperatures.
• Automotive-grade reliability — AEC‑Q200 qualified for customers requiring recognized component-level automotive test qualification.
• Reflow and assembly — SMD, lead-free reflow compatible with a 260°C peak solder profile (reflow up to two times) for standard surface-mount assembly processes.
• Physical and mounting details — Compact footprint with overall size L: 1.2 × D: 0.8 cm and recommended PCB land size of 8.3 × 8.3 mm for surface-mount placement.
• Environmental compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing on DC‑DC converters and power rails where AEC‑Q200 qualification and high-temperature endurance are required.
• DC‑DC converter output filtering — Low ESR and high ripple-current capability reduce voltage ripple and improve transient response on intermediate and output rails.
• Motor control and powertrain modules — High-temperature rating and long life support use in modules exposed to elevated operating temperatures and vibration-prone environments.
• Industrial power supplies — Reliable bulk capacitance and wide operating temperature range for high-reliability industrial converters and power modules.

Unique Advantages

• High-temperature durability: 4000 hours rated life at 135°C enables extended operation in thermally challenging assemblies.
• Low-loss power handling: 19 mΩ ESR at 100 kHz combined with high ripple-current ratings minimizes dissipation and supports efficient power conversion.
• Automotive-grade qualification: AEC‑Q200 status provides an established reliability baseline for vehicle electronics and related high-reliability applications.
• SMD-ready assembly: Lead-free reflow compatibility to 260°C and defined soldering profiles simplify integration into modern surface-mount production flows.
• Compact bulk capacitance: 270 µF in a 1.2 × 0.8 cm package delivers significant capacitance density for space-constrained boards.
• Specification-backed performance after stress: ESR limits after endurance include qualification at −40°C and during endurance recovery, supporting predictable behavior after thermal stress.
