Key Features

• Capacitance & Voltage — 47 µF rated at 10 V with ±20% tolerance for bulk and decoupling applications that need stable capacitance values.
• Conductive Polymer Electrolyte — Solid conductive polymer construction offering high capacitance in a small SMD radial-can package.
• High Ripple Current Handling — Rated ripple current of 180 mA at 120 Hz and 1.8 A at 300 kHz to support high-frequency power conversion and switching supplies.
• Low ESR — 25 mΩ ESR measured at 100 kHz (20°C) to reduce power loss and heating in high-current circuits.
• Extended Temperature & Lifetime — Operating range −55°C to 125°C with 3000 hours endurance at 125°C under rated voltage.
• SMD, Lead‑Free Reflow Compatible — Surface-mount radial-can package suitable for lead‑free reflow soldering with a 260°C peak profile.
• Compact Footprint — Case size L: 5.7 mm × D: 6.3 mm and recommended land size 6.5 × 6.5 mm for dense board layouts.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High-ripple power rails — Bulk decoupling and smoothing where elevated ripple current capability and low ESR reduce voltage ripple and thermal stress.
• Switching power supplies — Supports high-frequency switching environments with a 1.8 A ripple rating at 300 kHz and low ESR.
• Compact, thermally demanding assemblies — Small SMD package and 3000 h life at 125°C for designs that operate in elevated-temperature environments.

Unique Advantages

• High ripple tolerance: 1.8 A at 300 kHz and 180 mA at 120 Hz—helps maintain performance in high-frequency, high-current circuits.
• Low dissipation losses: 25 mΩ ESR at 100 kHz reduces heat generation and improves efficiency in power stages.
• Long high-temperature endurance: Rated for 3000 hours at 125°C, providing predictable long-term behavior in hot operating conditions.
• Lead‑free reflow ready: Compatible with a 260°C peak reflow profile for modern assembly processes.
• Space-efficient package: 5.7 × 6.3 mm footprint and defined land pattern enable dense board layouts without sacrificing bulk capacitance.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements.
