Key Features

• Electrical Performance — 470 µF nominal capacitance with ±20% tolerance; rated at 20 V for DC applications.
• Low Loss / Low ESR — tanδ = 0.12 (measured at 20°C, 120 Hz) and ESR = 20 mΩ measured at 20°C, 100 kHz, supporting efficient high-frequency operation.
• High Ripple Capability — Supports low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current up to 2 A (300 kHz) for filtering and smoothing in switching supplies.
• Wide Temperature & Long Life — Operating range from −55°C to +125°C with a rated load life of 3000 hours at 125°C.
• Leakage Current — Specified leakage current of 470 µA (after rated voltage application conditions).
• Package & Mounting — Surface-mount radial can (φ10 × 10L) designed for SMD assembly; compatible with lead-free reflow soldering up to a 260°C peak.
• Packaging for Production — Supplied in embossed carrier taping with moisture-proof packing; product status: mass production.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863) as noted in the product documentation.

Typical Applications

• Switching Power Supplies — High-frequency ripple capability (2 A at 300 kHz) and low ESR (20 mΩ) make this capacitor effective for output smoothing and EMI suppression in DC‑DC converters.
• Point-of-Load Decoupling — Compact φ10 × 10 mm SMD can provides bulk capacitance close to regulators and power rails where space is limited.
• Embedded and Industrial Electronics — Wide operating range (−55°C to +125°C) and 3000-hour endurance at 125°C support sustained performance in thermally demanding environments.

Unique Advantages

• High Capacitance in a Compact SMD Can: 470 µF in a φ10 × 10 mm package enables substantial energy storage without a large PCB footprint.
• High Ripple Tolerance: 2 A high-frequency ripple rating combined with 200 mA low-frequency ripple capability supports aggressive switching topologies and fast transient loads.
• Low ESR for Efficiency: 20 mΩ ESR at 100 kHz reduces I²R losses and improves voltage stability under dynamic load conditions.
• Extended High-Temperature Life: 3000 hours at 125°C provides predictable longevity for designs exposed to elevated operating temperatures.
• Manufacturing-Ready Packaging: Embossed carrier taping and moisture-proof packing streamline automated assembly and handling in volume production.
• Reflow-Compatible: Rated for lead-free reflow soldering with a 260°C peak, enabling modern surface-mount assembly processes.
