PCR1J390MCL1GS

The PCR1J390MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in an SMD radial can package, designed for high‑voltage, high‑reliability applications. As a member of the PCR series, it delivers low ESR and high ripple current capability combined with extended endurance at elevated temperatures.

Targeted use cases include automotive electronics and other systems that require robust performance through lead‑free reflow processes and sustained operation up to 125°C. Its combination of 63 V rating, 39 µF capacitance and AEC‑Q200 qualification addresses demanding power and thermal environments.

Key Features

• Capacitance & Voltage — 39 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, suitable for higher‑voltage DC rail applications.
• Low ESR & High Ripple Handling — ESR of 28 mΩ measured at 100 kHz and rated ripple current of 2.7 A at 100 kHz (1.35 A at 120 Hz), enabling efficient filtering and decoupling under dynamic load.
• High Temperature Endurance — Long life: 4000 hours at 125°C; operating temperature range −55°C to +125°C for reliable performance in harsh thermal environments.
• Automotive Qualification — AEC‑Q200 qualified, supporting use in automotive electronic systems that require component-level reliability verification.
• SMD, Reflow‑Capable Package — Surface mount radial can (chip type) designed for lead‑free reflow soldering; compatible with peak reflow temperatures up to 260°C per series soldering specification.
• Compliance — RoHS compliant in accordance with the referenced directives.
• Compact Footprint — Physical size L: 1.0 × D: 0.8 cm with recommended PCB land pattern 8.3 × 8.3 mm, enabling dense board integration.
• Polarized Electrolytic — Polarized construction suitable for standard electrolytic capacitor use cases.

Typical Applications

• Automotive Power Electronics — Decoupling, smoothing and energy buffering on intermediate rails and power stages in systems that require AEC‑Q200‑level components.
• Power Supply Filtering — Bulk and high‑frequency filtering on high‑voltage DC rails up to 63 V where low ESR and high ripple current are required.
• Harsh‑Environment Electronics — Electronics operating across −55°C to +125°C that must withstand extended high‑temperature endurance (4000 hours at 125°C).
• Surface‑Mount Production — Designs requiring SMD components compatible with lead‑free reflow soldering processes up to 260°C.

Unique Advantages

• High‑voltage capability: 63 V rating supports designs with elevated DC rails without stepping to larger capacitor families.
• Low ESR performance: 28 mΩ at 100 kHz reduces conduction losses and improves regulator stability at high switching frequencies.
• Robust ripple handling: Rated ripple currents of 2.7 A (100 kHz) and 1.35 A (120 Hz) enable reliable operation under continuous AC stress.
• Extended high‑temperature life: 4000 hours at 125°C provides predictable long‑term behavior for thermally demanding applications.
• Automotive‑grade reliability: AEC‑Q200 qualification supports use in vehicle electronics and other reliability‑sensitive systems.
• Reflow‑friendly SMD form factor: Surface mount radial can simplifies automated assembly while meeting lead‑free soldering profiles.
