RKS1C122MCNAJLGS

The RKS1C122MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 1.2 mF capacitance at a 16 V rating. It combines high capacitance, low equivalent series resistance, and high allowable ripple current in a compact φ10 × 12.4 mm SMD can.

Designed for general-purpose power applications, this component targets designs that require robust high-frequency performance and long-term reliability over a wide temperature range (−55 °C to 125 °C), with a rated life of 3000 hours at 125 °C.

Key Features

• Electrical Performance — 1.2 mF capacitance with ±20% tolerance and a rated voltage of 16 V; tan δ of 0.12 measured at 20 °C, 120 Hz for predictable loss characteristics.
• Low ESR — ESR specified at 20 mΩ (20 °C, 100 kHz), supporting efficient high-frequency decoupling and lower heat generation under ripple conditions.
• High Ripple Handling — Low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current of 2.0 A (300 kHz) for demanding power-filtering roles.
• Reliability & Endurance — Rated lifetime of 3000 hours at 125 °C and category temperature range from −55 °C to 125 °C for sustained operation in elevated-temperature environments.
• Package & Mounting — Surface-mount, radial can (SMD) package sized φ10 × 12.4 mm to support automated PCB assembly; supplied in embossed carrier taping with moisture-proof packing.
• Leakage & Polarization — Polarized device with specified leakage current of 960 µA after rated conditions, suitable for applications that accommodate that level of self-discharge.
• Environmental Compliance — RoHS compliant as stated in product data.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling where 1.2 mF capacitance and 16 V rating are required to stabilize DC rails.
• DC–DC converter outputs — Low ESR and 2.0 A high-frequency ripple capability help reduce output ripple and improve transient response.
• Embedded and industrial electronics — Wide operating temperature range (−55 °C to 125 °C) and 3000-hour life at 125 °C support long-term operation in temperature-challenging environments.
• Power hold-up and energy storage — High capacitance in a compact SMD can provides bulk energy storage for short-term hold-up and supply stabilization.

Unique Advantages

• High capacitance in a compact SMD package — 1.2 mF in a φ10 × 12.4 mm can minimizes board area for bulk capacitance requirements.
• Low ESR for improved efficiency — 20 mΩ ESR at 100 kHz reduces losses and thermal stress under high-frequency ripple conditions.
• Designed for high ripple environments — Rated for 2.0 A HF ripple current (300 kHz), enabling use on converter outputs and other noisy rails.
• Long-term high-temperature endurance — 3000 hours at 125 °C provides measurable assurance for sustained elevated-temperature operation.
• Surface-mount radial can with taped packaging — Embossed carrier taping and moisture-proof packing support automated pick-and-place and inventory storage.
• RoHS compliant — Conforms to environmental directives listed in the product information.
