RKS1E680MCNAHGGS

The RKS1E680MCNAHGGS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can (φ8 × 7.7 mm). It offers 68 µF capacitance at 25 V with polarization and is designed for applications that require low ESR and high allowable ripple current.

Key strengths include low equivalent series resistance (30 mΩ at 20°C/100 kHz), high-frequency ripple capability, and extended high-temperature endurance — rated for operation from −55°C to 125°C with a 3000 hour life at 125°C. Parts are shipped in embossed carrier taping with moisture-proof packing for SMT assembly.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance at 25 V with tolerance −20% to +20% for predictable decoupling and energy storage.
• Conductive Polymer Construction — Solid polymer electrolyte for low loss and stable high-frequency performance (tanδ 0.12 at 20°C, 120 Hz).
• Low ESR — 30 mΩ (measured at 20°C / 100 kHz) to support fast transient response and reduced thermal rise in high-frequency circuits.
• High Ripple Current Capability — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) for robust filtering in switching power stages.
• Extended High-Temperature Endurance — Rated life of 3000 hours at 125°C for use in elevated-temperature environments.
• SMD Can Package & Assembly Ready — Radial can SMD (φ8 × 7.7 mm) with recommended land pattern L: 8.3 × W: 8.3 mm; compatible with lead-free reflow up to 260°C per manufacturer soldering profile.
• Leakage Current — Specified leakage current of 100 µA to support predictable standby and bias behavior.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low ESR and high ripple capability improve regulator stability and reduce heat.
• DC‑DC Converters / Point‑of‑Load — Decoupling and energy hold-up close to switching devices for fast transient response.
• Industrial & Telecom Electronics — High-temperature operation (−55°C to 125°C) and long life support demanding thermal environments and continuous operation.
• Power Management Modules — Local energy storage and smoothing in compact, high-density power boards where SMD packaging is required.

Unique Advantages

• Low ESR for high-frequency performance: 30 mΩ at 100 kHz reduces losses and improves filtering at switching frequencies.
• High ripple current handling: 1.6 A at 300 kHz and 160 mA at 120 Hz enable reliable operation in both HF and LF ripple environments.
• High-temperature robustness: 3000 hour life at 125°C supports deployment in thermally demanding applications.
• Compact SMD can footprint: φ8 × 7.7 mm package and recommended land size (8.3 × 8.3 mm) simplify placement in space-constrained designs.
• Manufacturing friendly: Lead-free reflow compatibility and moisture-proof embossed carrier taping support streamlined SMT assembly.
• Predictable leakage behavior: Specified leakage current (100 µA) aids bias and standby current budgeting.
