RNS1D680MDN1

The RNS1D680MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, rated 68 µF at 20 V. It combines low equivalent series resistance and high-frequency ripple capability with a compact φ8×11.5 mm package for general-purpose electronic designs.

Engineered for applications that require stable capacitance, low loss, and reliable endurance, this part offers a broad operating temperature range and production-ready packaging options for standard assembly and bulk handling.

Key Features

• Capacitance & tolerance — 68 µF with tolerance of -20% to +20% at 120 Hz, 20°C, suitable for bulk energy storage and smoothing tasks.
• Rated voltage — 20 V DC rating for low-voltage power rails.
• Conductive polymer solid electrolyte — Polymer-based construction delivering low loss characteristics and solid-electrolyte reliability.
• Low ESR & loss tangent — ESR of 25 mΩ at 20°C/100 kHz and tanδ of 0.06 (20°C, 120 Hz) for reduced heat generation and improved high-frequency performance.
• High ripple current capability — 360 mA at 120 Hz (low frequency) and 3.6 A at 300 kHz (high frequency) to handle switching and ripple loads.
• Leakage current — 204 µA (specified leakage condition) for predictable standby behavior.
• Reliability & endurance — Rated life of 2000 hours at 105°C; operating temperature range −55°C to +105°C.
• Package & mounting — Radial lead can, size φ8×11.5 mm, lead spacing 3.5 mm (±0.5 mm), available in Bulk (no terminal forming) or Bag packing; currently in mass production.

Typical Applications

• Power supply smoothing — Low ESR (25 mΩ) and high ripple current capacity make this capacitor suitable for smoothing outputs on DC‑DC converters and switching power supplies.
• High-frequency power circuits — ESR specified at 100 kHz and rated HF ripple current at 300 kHz support decoupling and energy delivery in high-frequency switching environments.
• General-purpose electronics — Broad temperature range (−55°C to +105°C) and solid electrolyte construction support reliable operation across diverse industrial and consumer applications.

Unique Advantages

• Low loss at high frequency — 25 mΩ ESR at 100 kHz and tanδ 0.06 reduce power dissipation in high-frequency circuits.
• High ripple handling — 3.6 A capability at 300 kHz enables robust performance under heavy switching ripple conditions.
• Wide temperature endurance — Specified for −55°C to +105°C with a 2000-hour rating at 105°C for sustained reliability in demanding environments.
• Predictable leakage performance — Specified leakage current (204 µA) after rated voltage application supports predictable bias behavior.
• Compact radial form factor — φ8×11.5 mm can with 3.5 mm lead spacing simplifies board layout for through-hole designs while offering production packaging options.
• Mass-production availability — Standard packaging options and mass-production status support volume procurement and supply continuity.
