LLS1C123MELA

The LLS1C123MELA is a Nichicon LLS series snap‑in aluminum electrolytic capacitor offering 12,000 µF capacitance at a 16 V rating in a compact φ25 × 25 mm can. It is a polarized, radial snap‑in package designed for general‑purpose power applications requiring high bulk capacitance on board‑level DC rails.

Built for sustained operation, this part is specified for operation from −40°C to +85°C and is endurance‑rated for 3,000 hours at 85°C under rated ripple current conditions, providing predictable life and performance in continuous‑use environments. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance at a rated voltage of 16 V, with capacitance tolerance of −20% to +20% measured at 120 Hz, 20°C.
• Snap‑In Radial Package — Can‑type, snap‑in terminals for secure board mounting in a φ25 × 25 mm form factor.
• Endurance — Rated to withstand 3,000 hours of applied rated ripple current at 85°C; capacitors meet specified limits for capacitance change, tan δ and leakage after endurance test.
• High Ripple Current Handling — Low‑frequency ripple current 3.01 A (120 Hz) and high‑frequency ripple current 3.462 A (50 kHz) support continuous ripple conditions on DC rails.
• Leakage Current — Specified leakage current of 1,310 µA (measured after application of rated voltage), consistent with standard aluminum electrolytic performance.
• Loss Tangent (tan δ) — Maximum tan δ of 0.50 at 120 Hz and 20°C for the 16 V rating, measured under standard conditions.
• Operating Temperature — −40°C to +85°C operating range for broad environmental compatibility within the LLS series specification.
• RoHS Compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply bulk smoothing — High 12,000 µF capacitance at 16 V provides bulk energy storage and smoothing on 16 V DC rails where sustained ripple handling is required.
• Board‑level DC filtering — Radial snap‑in package and high ripple current ratings suit board‑mounted DC filtering in general‑purpose electronic equipment.
• Hold‑up and energy buffering — Large capacitance combined with 3,000‑hour endurance at 85°C supports temporary energy buffering and hold‑up on low‑voltage power buses.

Unique Advantages

• Sustained ripple capability: Specified ripple current of 3.01 A (120 Hz) and 3.462 A (50 kHz) enables continuous operation under real ripple conditions without immediate performance degradation.
• Predictable endurance: 3,000‑hour rated life at 85°C under rated ripple current provides designers with a defined lifecycle metric for thermal and electrical stress planning.
• High bulk capacitance in compact package: 12,000 µF in a φ25 × 25 mm can delivers substantial energy density for board‑level applications where space is constrained.
• Clear electrical characterization: Specified tan δ (0.50 at 120 Hz, 20°C) and measured leakage current allow accurate modelling of loss and standby current in system power budgets.
• RoHS compliance: Conforms to RoHS requirements for applications requiring restricted‑substance compliance.
