PCH1H271MCL1GS

The PCH1H271MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor from Nichicon’s PCH series. It is an SMD, polarized aluminum-can style capacitor designed for high-temperature operation and long-term reliability.

Designed for demanding electronic systems — including automotive electronics — the device delivers high capacitance (270 µF), low ESR, and high ripple-current handling in a compact surface-mount package, with extended life at elevated temperatures.

Key Features

• Capacitance and Voltage: 270 µF nominal capacitance with a rated voltage of 50 V and ±20% tolerance at 120 Hz, 20 °C.
• Low ESR: 15 mΩ equivalent series resistance measured at 100 kHz (20 °C), supporting efficient high-frequency operation.
• High Ripple Current: Ripple current capability of 1.55 A at 120 Hz and 3.1 A at 100 kHz, enabling effective smoothing under dynamic loads.
• Extended High-Temperature Life: Qualified for 4000 hours at 135 °C endurance; specified to meet capacitance, tan δ, ESR and leakage limits after this test.
• Wide Operating Range: Temperature range from −55 °C to +135 °C for use in harsh thermal environments.
• SMD, Reflow-Compatible Package: Radial can, surface-mount mounting type with compatibility for lead‑free reflow soldering to a 260 °C peak (per specified soldering profile).
• Reliability & Compliance: AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), with ESR performance characterized after endurance at −40 °C.
• Compact Footprint: Package dimensions L: 1.6 cm × D: 1.0 cm and recommended land size L: 1.03 × W: 1.03 cm for PCB layout.

Typical Applications

• Automotive Electronics: Suited for vehicle systems that require AEC‑Q200 qualification and long-term performance at elevated temperatures.
• Power Supply Filtering and Smoothing: Low ESR and high ripple-current capability make the capacitor effective for decoupling and bulk smoothing in power rails and DC–DC converters.
• High-Temperature Industrial Electronics: Engineered for use in electronics exposed to extended high temperatures thanks to its −55 °C to +135 °C rating and 4000-hour endurance at 135 °C.

Unique Advantages

• Long High-Temperature Endurance: 4000 hours at 135 °C provides quantified lifetime performance for designs operating in hot environments.
• Measured Low ESR: 15 mΩ at 100 kHz reduces voltage drop and heat generation under high-frequency ripple, improving power-stage efficiency.
• High Ripple Handling: Rated ripple currents (1.55 A at 120 Hz; 3.1 A at 100 kHz) support robust performance in dynamic power applications.
• AEC‑Q200 Qualified: Delivers the qualification level required for many automotive-grade applications, supporting system reliability objectives.
• Reflow-Ready SMD Can: Compatible with lead-free reflow soldering to a 260 °C peak, simplifying assembly for modern SMT production flows.
• Compact, PCB-Friendly Footprint: Small can-type SMD package and defined land pattern aid in high-density board layouts.
