RNL1C681MDS1

The RNL1C681MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can, offering 680 µF capacitance at a 16 V rating. It combines low ESR and high ripple‑current capability in a compact φ8×16 mm package intended for general‑purpose electronic applications.

Designed for board‑level use where long life and wide temperature operation are required, this part supports operation from −55 °C to 105 °C and a rated load life of 2000 hours at 105 °C.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 16 V and tolerance ±20% (120 Hz, 20 °C).
• Low Loss / Low ESR — Tangent of loss angle (tan δ) of 0.12 and ESR of 8 mΩ measured at 20 °C / 100 kHz for reduced dissipation and efficient high‑frequency performance.
• High Ripple Current — Rated ripple current of 700 mA at 120 Hz (low frequency) and 7 A at 300 kHz (high frequency), with frequency coefficients provided in the datasheet.
• Leakage Current — Specified leakage current of 1088 µA after 2 minutes at 20 °C following rated voltage application.
• Robust Temperature & Life Ratings — Operating range −55 °C to +105 °C and load life specified at 2000 hours at 105 °C under rated voltage.
• Radial Lead, Compact Can — φ8×16 mm case with 3.5 mm lead spacing (±0.5 mm), suitable for through‑hole radial mounting; available in bulk or bag packing.
• Regulatory Compliance — RoHS compliant as stated in the product data.

Typical Applications

• General‑purpose electronics — Intended for a wide range of general‑purpose applications where a combination of high capacitance and low ESR is required.
• Board‑level power modules — Suited to designs that benefit from the capacitor's high ripple‑current capability and low ESR in a compact radial package.
• Industrial and commercial equipment — Applicable where extended operating temperature range (−55 °C to 105 °C) and defined load life at elevated temperature are required.

Unique Advantages

• High ripple handling: 7 A rated ripple at high frequency (300 kHz) and 700 mA at 120 Hz reduce stress on upstream circuitry and support demanding load conditions.
• Low ESR for efficiency: 8 mΩ ESR at 100 kHz minimizes power loss and thermal rise during high‑frequency operation.
• Temperature and life robustness: −55 °C to 105 °C operating range with a 2000‑hour life rating at 105 °C provides predictable endurance in elevated‑temperature environments.
• Compact radial form factor: φ8×16 mm can with 3.5 mm lead spacing delivers high capacitance density in a through‑hole package for straightforward board assembly.
• Clear specification set: Measured tan δ (0.12), leakage (1088 µA), and ESR values give design engineers quantifiable parameters for power‑management tradeoffs.
• RoHS compliant and production ready: Declared RoHS compliance and mass production status simplify procurement and regulatory planning.
