RNS1C680MDN1

The RNS1C680MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial can package offering 68 µF capacitance at a 16 V rating. Designed for general-purpose electronic designs, it delivers low ESR and high ripple-current capability in a compact radial-leaded form.

This part is suited for designers who need reliable filtering and decoupling performance across a wide temperature range (−55°C to 105°C) with long endurance (2000 hours at 105°C) and a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Conductive Polymer Electrolyte — Solid polymer construction for stable performance and reduced equivalent series resistance compared with traditional wet electrolytes.
• Low ESR — 25 mΩ ESR measured at 20°C/100 kHz, supporting low-loss operation at high frequencies.
• High Ripple‑Current Handling — Rated ripple current of 360 mA at 120 Hz (low frequency) and 3.6 A at 300 kHz (high frequency), enabling effective smoothing in switching and high-frequency circuits.
• Wide Temperature & Endurance — Operating range −55°C to 105°C with 2000 hours endurance at 105°C under rated voltage.
• Radial Lead Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) in bulk/no terminal forming packaging for through-hole assembly.
• Leakage & Reliability — Specified leakage current of 163 µA after the standard conditioning interval.

Typical Applications

• General-purpose power filtering — Provides decoupling and smoothing in general-purpose electronic designs that require a 16 V, 68 µF polymer capacitor with low ESR.
• High-frequency switching circuits — Low ESR and high ripple-current rating make it suitable for high-frequency converter output filtering and local decoupling.
• Compact through-hole assemblies — Radial-lead can package with 3.5 mm lead spacing fits small PCB footprints where reliable bulk capacitance is required.

Unique Advantages

• Low-loss operation: 25 mΩ ESR at 100 kHz reduces power dissipation and supports efficient high-frequency performance.
• High ripple capacity: 3.6 A ripple-current rating at 300 kHz allows robust handling of switching currents in modern power stages.
• Wide thermal range and endurance: −55°C to 105°C operating range and 2000 hours rating at 105°C improve reliability in sustained elevated-temperature environments.
• Compact radial package: φ8 × 11.5 mm can with 3.5 mm lead spacing provides a space-efficient through-hole solution for board-level implementations.
• Predictable leakage behavior: Specified leakage current (163 µA) after standard conditioning supports predictable power budgets and system standby behavior.
