PCH1V331MCL1GS

The PCH1V331MCL1GS is a chip-type conductive polymer aluminum solid electrolytic capacitor from Nichicon’s PCH series. It delivers 330 µF at a 35 V rating in a surface-mount package engineered for high-temperature and high-reliability applications.

With low ESR, high ripple-current capability and an extended endurance rating to 135°C, this device is designed to support demanding power-filtering and decoupling requirements where thermal endurance and electrical performance are critical.

Key Features

• Dielectric / Core Conductive polymer aluminum solid electrolyte in a chip-type SMD package for stable capacitance and improved ripple performance.
• Electrical Characteristics 330 µF nominal capacitance with ±20% tolerance and tanδ (DF) of 0.08 measured at 20°C, 120 Hz.
• Low ESR and High Ripple Capability ESR of 16 mΩ at 20°C / 100 kHz, low-frequency ripple current of 1.4 A (120 Hz) and high-frequency ripple current of 2.8 A (100 kHz).
• Leakage Current Specified leakage current of 346 µA (measured after application of rated voltage).
• High-Temperature Endurance Rated operating temperature range −55°C to +135°C with a life/endurance rating of 4000 hours at 135°C.
• Automotive-Grade Reliability AEC-Q200 rated for designs that require automotive-level qualification.
• Package and Mounting Chip-type surface-mount can (φ10 × 12.7 mm) with embossed carrier taping and moisture-proof packing for automated assembly and storage.
• RoHS Compliance Conforms to RoHS directives as specified.

Typical Applications

• Automotive power systems — Low ESR and high ripple-current handling make the PCH1V331MCL1GS suitable for power-rail decoupling and smoothing in automotive electronic control units and power modules.
• High-temperature electronics — Endurance to 4000 hours at 135°C enables use in ECU assemblies and other electronics exposed to elevated operating temperatures.
• Power conversion and regulation — High-frequency ripple-current capability and low ESR support DC–DC converter output filtering and bulk decoupling on compact SMD boards.

Unique Advantages

• High ripple tolerance: 2.8 A at 100 kHz and 1.4 A at 120 Hz provide margin for demanding switching regulator outputs.
• Low ESR for improved efficiency: 16 mΩ ESR at 100 kHz reduces dissipation and helps maintain stable voltage rails under transient loads.
• Extended high-temperature life: 4000 hours at 135°C supports long-term reliability in thermally stressed environments.
• AEC-Q200 rated: Explicit automotive qualification supports deployment in vehicle systems requiring industry-recognized reliability standards.
• SMD-ready packaging: Chip-type can with embossed carrier taping and moisture-proof packing simplifies automated placement and inventory handling.
• Documented electrical control: Measured tanδ, leakage, and ESR specifications give predictable behavior for power-system design and simulation.
