RDS1C330MCNAFEGS

The RDS1C330MCNAFEGS is a conductive polymer aluminum solid electrolytic surface-mount capacitor from Nichicon’s RDS series. It delivers high capacitance in a compact SMD can package and is engineered for applications that require high ripple current handling and extended life at elevated temperatures.

Key design attributes include a 33 µF, 16 V rating, a wide operating temperature range from –55 °C to 125 °C, and a rated load life of 3000 hours at 125 °C, making it suitable for demanding electronic assemblies that must tolerate thermal and ripple stress while using lead‑free reflow processes.

Key Features

• Electrical Performance  33 µF capacitance at 16 V with ±20% tolerance (120 Hz, 20 °C); low ESR specified at 24 mΩ (100 kHz, 20 °C) to support high-frequency operation.
• High Ripple Current Capability  Rated ripple current up to 2.1 A at 300 kHz and 210 mA at 120 Hz, enabling effective filtering and smoothing in high-ripple environments.
• Extended High-Temperature Life  Load life of 3000 hours at 125 °C under rated voltage, with endurance limits for capacitance and ESR defined by the RDS series specifications.
• Wide Temperature Range  Operating temperature from –55 °C to 125 °C for designs exposed to wide thermal variation.
• SMD, Reflow-Compatible Package  Surface-mount, radial can package sized φD×L = 6.3 × 5.7 mm (L: 5.7 × D: 6.3 mm); compatible with lead-free reflow peak conditions up to 260 °C.
• Leakage Current Specification  Leakage current after 2 minutes at rated voltage is limited to 0.3CV or 700 µA (whichever is greater), per the series specifications.
• RoHS Compliance  Compliant with the RoHS directive (2011/65/EU, (EU)2015/863) and suitable for lead-free assembly flows.

Typical Applications

• Power supply filtering  Used as input/output smoothing and bulk decoupling where high ripple current and low ESR are required to stabilize voltage rails.
• DC–DC converters  Serves as a compact bulk or output capacitor in switching converters, benefiting from the high ripple current rating at switching frequencies.
• Industrial and rugged electronics  Applicable in assemblies that operate across wide temperatures (–55 °C to 125 °C) and require long-term stability under elevated temperatures.

Unique Advantages

• High ripple tolerance:  2.1 A rated ripple current at 300 kHz and low ESR (24 mΩ) reduce voltage ripple and heat buildup in high-frequency circuits.
• Compact SMD can package:  6.3 × 5.7 mm nominal footprint provides high capacitance density for space-constrained PCBs while supporting standard lead‑free reflow processes to 260 °C.
• Long high-temperature life:  3000 hours at 125 °C demonstrates durability for applications exposed to sustained elevated temperatures.
• Wide operating range:  –55 °C to 125 °C operation covers harsh environmental conditions without sacrificing performance.
• Predictable leakage behavior:  Leakage current bounded by 0.3CV or 700 µA (after 2 minutes) aids in worst-case power-budget planning.
• RoHS-compliant lead-free assembly:  Conforms to current RoHS requirements and is compatible with lead‑free manufacturing flows.
