RNL1C122MDS1

The RNL1C122MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, offering 1200 µF capacitance at 16 V. It is designed for general-purpose electronic applications where low ESR, high ripple current handling and reliable operation across a wide temperature range are required.

With a compact φ8×20L package and 3.5 mm lead spacing, this mass-production part from Nichicon combines high capacitance density with measured performance characteristics such as 8 mΩ ESR (at 100 kHz) and a rated operating range of –55°C to +105°C.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for stable electrical characteristics and improved ripple handling compared with traditional electrolytics.
• Capacitance & voltage — 1200 µF nominal capacitance at a 16 V rated voltage, tolerance ±20% (at 120 Hz, 20°C).
• Low ESR — ESR of 8 mΩ measured at 100 kHz, supporting lower losses and improved high-frequency performance.
• High ripple current capability — Rated ripple current up to 7.5 A at high frequency (specified at 300 kHz in part data) and 750 mA at 120 Hz; frequency coefficients provided in the datasheet.
• Wide temperature range — Specified for operation from –55°C to +105°C to accommodate demanding thermal environments.
• Load life — Rated lifetime of 2000 hours at 105°C under specified conditions.
• Radial lead package — φ8×20L can with 3.5 mm lead spacing for through-hole mounting; available packaged in bulk (no terminal forming) or bag packing.
• RoHS compliant — Meets RoHS directive requirements as stated in the product data.
• Leakage current — Characterized leakage current of 1920 μA at 20°C after 2 minutes (as specified for this capacitance and case size).

Typical Applications

• General-purpose electronics — Provides bulk capacitance and low-ESR performance for power rails in a wide range of consumer and industrial electronic circuits.
• Power supply filtering — Suited to smoothing and ripple suppression duties where high ripple current capability and low ESR are required.
• High-frequency circuits — Low ESR at 100 kHz and specified ripple performance make it appropriate for circuits with significant high-frequency content.

Unique Advantages

• Measurable low ESR (8 mΩ) — Directly reduces conduction losses and improves voltage stability under dynamic loads.
• High ripple current rating — Handles up to 7.5 A at high frequency, enabling reliable operation in demanding power applications.
• Wide operating temperature — –55°C to +105°C rating supports diverse environmental and thermal conditions.
• Compact radial can — φ8×20L footprint and 3.5 mm lead spacing allow dense PCB layouts while retaining through-hole robustness.
• Defined endurance — 2000 hours at 105°C gives a clear expectation of long-term performance in elevated-temperature assemblies.
• RoHS compliance and mass-production availability — Conforms to RoHS and is available in production quantities for design and volume manufacturing.
