PCH1D681MCL1GS

The PCH1D681MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package. It delivers high capacitance (680 µF) at a 20 V rating with low equivalent series resistance and elevated ripple-current handling.

Designed for demanding environments, the device is specified for operation from -55 °C to 135 °C, rated for 4,000 hours at 135 °C, and is AEC-Q200 qualified and RoHS compliant—making it suitable for automotive and other high-reliability applications that require compact, high-capacitance smoothing and decoupling components.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 20 V rated voltage and ±20% tolerance, providing substantial bulk energy storage in a compact SMD form.
• Low ESR & High Ripple Capability — Low ESR of 14 mΩ measured at 100 kHz and ripple-current ratings of 3 A at 100 kHz and 1.5 A at 120 Hz for improved power rail stability and thermal performance under ripple loading.
• Wide Temperature Range — Specified operation from -55 °C to 135 °C, with endurance demonstrated at 4,000 hours at 135 °C for high-temperature reliability.
• Reliability & Qualification — AEC-Q200 qualified and designed with polymer solid electrolyte chemistry for robust performance over life; endurance and damp-heat characteristics are defined in the datasheet.
• SMD Can Package and Land Size — Surface-mount radial can style (chip type) with board land recommendation of 1.03 × 1.03 cm for straightforward PCB layout and automated assembly.
• Lead-free Reflow Compatible — Compliant with lead-free reflow soldering up to a 260 °C peak, allowing standard surface-mount assembly processes.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863) for regulatory and product stewardship requirements.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification, wide temperature range, and long-life specification make this capacitor suitable for onboard power filtering, decoupling, and energy storage in automotive ECUs and power modules.
• Power Management Modules — Low ESR and high ripple-current capability support DC–DC converter output smoothing and bulk decoupling in compact power assemblies.
• Harsh‑Environment Electronics — The high-temperature endurance (4,000 hours at 135 °C) and operation down to -55 °C suit electronics that must maintain performance in elevated-temperature or thermally cycling environments.

Unique Advantages

• High Capacitance in SMD Form — 680 µF nominal capacitance provides bulk energy storage while saving board area compared with larger discrete options.
• Improved Thermal Endurance — Rated for 4,000 hours at 135 °C, enabling longer service life in high-temperature applications and reducing maintenance or field replacement frequency.
• Low Losses and Stable Filtering — 14 mΩ ESR at 100 kHz and defined ripple ratings improve converter efficiency and maintain voltage stability under dynamic load conditions.
• Automotive-Grade Qualification — AEC-Q200 qualification supports use in automotive-grade designs where component qualification is required.
• Assembly Compatibility — Lead-free reflow up to 260 °C and a defined board land pattern simplify integration into automated SMT production flows.
• Regulatory Compliance — RoHS conformity supports global product compliance and environmental requirements.
