RNL1E681MDS9

The RNL1E681MDS9 is a Nichicon RNL series conductive-polymer aluminum solid electrolytic capacitor in a radial-lead can. It provides 680 µF capacitance at a 25 V rating with a compact φ10 × 20 mm package and 5.0 mm lead spacing for through‑hole mounting.

Designed for general-purpose electronic designs, this part combines low ESR and high ripple-current capability with a wide operating temperature range to support power‑filtering and decoupling applications that require robust performance up to 105°C.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in 25 V designs.
• Low ESR / High Frequency Performance — ESR of 10 mΩ measured at 20°C / 100 kHz, supporting low-loss operation and efficient high-frequency decoupling.
• High Ripple Current Capability — Rated ripple currents of 810 mA at 120 Hz and 8.1 A at 300 kHz enable effective handling of both low- and high-frequency ripple in power circuits.
• Solid Conductive Polymer Electrolyte — Solid polymer construction provides stability in ESR and ripple handling compared to liquid electrolytes.
• Thermal and Lifetime Specs — Operating temperature range −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Electrical Characteristics — tanδ (DF) of 0.12 measured at 20°C / 120 Hz and leakage current of 1700 µA (measurement condition: after 2 minutes’ application at 20°C).
• Package & Mounting — Radial lead, can-style package sized φ10 × 20 mm with 5.0 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Compliance & Availability — RoHS compliant and in mass production as part of Nichicon’s RNL series.

Typical Applications

• Power Supply Filtering — Smoothing and decoupling in 25 V power rails where 680 µF and low ESR (10 mΩ) reduce voltage ripple and improve regulation.
• High-Frequency Decoupling — Use in circuits requiring high-frequency ripple handling, supported by an 8.1 A ripple current rating at 300 kHz.
• General Purpose Electronics — General-purpose energy storage and transient suppression in industrial and consumer designs operating within −55°C to +105°C.

Unique Advantages

• Low-loss operation: 10 mΩ ESR at 100 kHz reduces power dissipation and heating in high-current applications.
• Broad ripple-frequency capability: Rated ripple currents at both 120 Hz and 300 kHz let the device serve across low- and high-frequency domains without specification mismatch.
• Temperature resilience: −55°C to +105°C operating range and 2000 h life at 105°C provide predictable performance in elevated-temperature environments.
• Solid polymer reliability: Conductive polymer construction offers stable electrical parameters and controlled leakage behavior (1700 µA specified condition).
• Compact through-hole package: φ10 × 20 mm can with 5.0 mm lead spacing delivers high capacitance density for radial-lead assemblies.
