• RoHS Compliant Conforms to RoHS directive requirements.

Typical Applications

• Power Supply Filtering and Smoothing — Low ESR (25 mΩ at 100 kHz) and high ripple ratings make this capacitor suitable for bulk filtering and smoothing in low-voltage power supplies.
• Decoupling for High-Frequency Converters — High-frequency ripple capability (2.82 A at 300 kHz) supports decoupling in DC‑DC converter outputs and switching regulator stages.
• General-Purpose Electronic Circuits — Radial lead package and general-purpose classification fit consumer and industrial boards that require reliable capacitive stabilization.

Unique Advantages

• Low ESR for efficient HF performance: 25 mΩ ESR at 100 kHz reduces I²R losses and improves high-frequency decoupling effectiveness.
• High ripple-current handling: Rated ripple current of 2.82 A at 300 kHz and 282 mA at 120 Hz enables robust operation in both high- and low-frequency ripple environments.
• Thermal endurance: 2000 hours rated life at 105°C and an operating range from −55°C to 105°C provide stability across wide temperature conditions.
• Compact radial form factor: φ6.3×10L case and 2.5 mm lead spacing simplify through-hole placement and board-level integration.
• Predictable leakage: Specified leakage current (320 µA) allows straightforward power budgeting in low-voltage designs.
• Regulatory compliance: RoHS compliance supports regulatory requirements for lead-free assemblies.
