LLS1H123MELC

The LLS1H123MELC from Nichicon is a snap‑in, radial can aluminum electrolytic capacitor in the LLS series, providing 12,000 µF of capacitance at a 50 V rating. It is designed for general‑purpose applications that require high bulk capacitance and reliable endurance under continuous ripple stress.

Key attributes include snap‑in mounting for secure panel or chassis installation, a rated operating range of −40 °C to +85 °C, and a 3000‑hour endurance at 85 °C under rated ripple current conditions.

Key Features

• Capacitance and Tolerance — 12,000 µF nominal capacitance with tolerance of −20% to +20%, offering substantial energy storage for bulk filtering and decoupling in general‑purpose designs.
• Rated Voltage — 50 V rated voltage suitable for mid‑voltage DC applications requiring robust capacitance.
• Loss Characteristics — Tangent of loss angle (tan δ) 0.30 measured at 20 °C, 120 Hz (for the 50 V rating), providing defined dissipation performance for design margining.
• Ripple Current Capability — Low‑frequency ripple current of 5.69 A at 120 Hz and high‑frequency ripple current of 6.543 A at 50 kHz, enabling sustained operation under AC ripple conditions.
• Leakage Current — Specified leakage current of 2320 µA, measured per the product data conditions, for predictable standby and charged state behavior.
• Endurance and Temperature — 3000 hours endurance at 85 °C while withstanding rated ripple current; operating temperature range −40 °C to +85 °C.
• Package and Mounting — Radial, snap‑in can package (φ35 × 40 mm L; listed dimensions L: 4 × D: 3.5 cm) supplied in tray packing for production handling and assembly.
• Compliance and Production — RoHS‑compliant and in mass production as part of Nichicon’s LLS series of 85 °C standard snap‑in capacitors.

Typical Applications

• General‑purpose power systems — Used where large bulk capacitance and a 50 V rating are required for energy storage and smoothing.
• Industrial equipment — Suitable for general‑purpose industrial designs that demand long endurance at elevated temperature (3000 h at 85 °C).
• Chassis or panel mounted assemblies — Snap‑in radial can form factor enables secure mechanical mounting in assemblies that require through‑frame capacitor installation.

Unique Advantages

• High bulk storage: 12,000 µF provides significant charge capacity for smoothing and bulk decoupling, reducing the need for multiple smaller devices.
• Defined thermal endurance: Rated for 3000 hours at 85 °C under rated ripple current, enabling predictable maintenance and lifecycle planning.
• Clear ripple specifications: Separate low‑ and high‑frequency ripple current ratings (5.69 A at 120 Hz, 6.543 A at 50 kHz) allow designers to size capacitors to actual operating conditions.
• Snap‑in mechanical retention: Radial snap‑in can package simplifies installation in chassis or panel layouts and supports automated handling with tray packing.
• Measured dissipation data: tan δ specified at 20 °C, 120 Hz (0.30 for 50 V) assists in thermal and loss budgeting during design.
