RNL1E681MDSCSQ

The RNL1E681MDSCSQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, offering 680 µF capacitance at a 25 V rating. It is designed for general-purpose electronic applications that require high capacitance density, low equivalent series resistance and defined ripple-current capability.

Key value propositions include low ESR for improved high-frequency behavior, a wide operating temperature range down to −55 °C, and long endurance (5000 hours at 105 °C), making it suitable for demanding, long-life designs.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a rated voltage of 25 V with tolerance of −20% to +20%.
• Conductive Polymer Solid Electrolyte — Solid polymer construction combined with aluminum electrochemistry, explicitly specified in the product designation.
• Low ESR & Frequency Performance — ESR of 10 mΩ measured at 20 °C / 100 kHz and tanδ of 0.12 (20 °C, 120 Hz), supporting efficient high-frequency operation.
• High Ripple Current Capability — Specified ripple current ratings: 810 mA at 120 Hz (low frequency) and 8.1 A at 300 kHz (high frequency), enabling robust ripple handling across wide frequency ranges.
• Thermal Endurance — Rated operating temperature range −55 °C to +105 °C with a rated lifetime of 5000 hours at 105 °C.
• Radial Lead Package — φ10 × 20 mm can with 5.0 mm lead spacing (±0.5 mm tolerance) in a radial-lead through-hole format; available in bulk or bag packing (no terminal forming).
• Compliance & Availability — RoHS compliant and in mass production status.

Typical Applications

• General-purpose electronics — Provides 680 µF / 25 V bulk capacitance with low ESR (10 mΩ) for general-purpose circuit designs requiring stable capacitance and ripple handling.
• High-frequency power stages — With ESR specified at 100 kHz and a high-frequency ripple current rating of 8.1 A at 300 kHz, it addresses circuits with significant HF ripple content.
• Extended-temperature deployments — The −55 °C to +105 °C rating and 5000 h endurance at 105 °C support applications that require reliable operation across a wide temperature range.

Unique Advantages

• Low ESR for improved HF performance: 10 mΩ ESR at 20 °C / 100 kHz reduces losses and supports higher-frequency operation as specified.
• High ripple-current capability: Defined ripple ratings of 810 mA (120 Hz) and 8.1 A (300 kHz) provide predictable thermal and electrical behavior under AC loading.
• Long-term thermal reliability: 5000 hours rated life at 105 °C offers designers a clear endurance specification for elevated-temperature use.
• Compact radial through-hole form factor: φ10 × 20 mm can with 5.0 mm lead spacing (±0.5 mm) supports conventional through-hole assembly and mechanical stability.
• Regulatory compliance and production readiness: RoHS compliant and available in mass-production quantities with bulk or bag packing options.
