PCH1H820MCL1GS

The PCH1H820MCL1GS from Nichicon is a conductive-polymer aluminum solid electrolytic chip capacitor in an SMD can package. It delivers 82 µF at a 50 V rating with low equivalent series resistance and high ripple-handling capability for demanding power and temperature environments.

Designed for applications requiring high reliability and extended life, this part targets automotive and industrial power systems where high temperature endurance, low ESR, and robust soldering performance are required.

Key Features

• Capacitance & Voltage — 82 µF capacitance at a 50 V rated voltage, with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Conductive Polymer Construction — Solid conductive polymer electrolyte for low ESR and improved ripple performance compared with traditional electrolytics.
• Low ESR — ESR specified as 34 mΩ at 100 kHz, 20°C, enabling better efficiency in power conversion and decoupling roles.
• High Ripple Current — Rated ripple current of 1.6 A at 100 kHz and 800 mA at 120 Hz to support dynamic load conditions.
• Extended High‑Temperature Life — Qualified for 4000 hours at 135°C with endurance limits defined for capacitance, tan δ, ESR and leakage current.
• Wide Operating Temperature — Specified operating range from −55°C to +135°C for use in thermally challenging systems.
• Surface-Mount Can Package — Chip (radial can SMD) configuration optimized for automated assembly; nominal dimensions L: 0.8 cm × D: 1.0 cm and recommended land size L: 1.03 cm × W: 1.03 cm.
• Reflow-Compatible — Lead-free reflow soldering condition supported with a peak temperature up to 260°C (pre‑heat and time limits apply per manufacturer guidance).
• Quality & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting use in regulated and automotive environments.

Typical Applications

• Automotive Power Systems — Bulk decoupling and smoothing in vehicle power electronics, benefiting from AEC‑Q200 qualification and extended high‑temperature life.
• DC–DC Converters — Input/output filtering and energy storage where low ESR and high ripple current improve conversion efficiency and transient response.
• Industrial Power Supplies — Temperature‑resilient filtering and stabilization in industrial controllers and power modules operating up to 135°C.
• Telecommunications Power Rails — Bulk and decoupling capacitors for high-frequency circuits that require low ESR at 100 kHz and reliable long-term operation.

Unique Advantages

• High Temperature Endurance: Rated for 4000 hours at 135°C, enabling longer service life in elevated-temperature applications and reducing maintenance frequency.
• Low ESR for Improved Efficiency: 34 mΩ ESR at 100 kHz lowers power loss and heat generation in high-frequency power circuits.
• Robust Ripple Handling: 1.6 A ripple current (100 kHz) supports dynamic loads and reduces the need for parallel capacitors.
• Automotive‑Grade Qualification: AEC‑Q200 qualification provides a verified reliability baseline for automotive and similarly demanding designs.
• Reflow-Ready SMD Format: Chip can package and lead‑free reflow compatibility (260°C peak) streamline automated PCB assembly and manufacturing flow.
• Regulatory Compliance: RoHS conformity ensures alignment with environmental and regulatory requirements.
