The LLS1H123MELB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor offering 12,000 µF capacitance at a 50 V rating. It is part of the LLS series designed for general‑purpose power applications that require large bulk capacitance and sustained ripple current capability.

This capacitor delivers a combination of high capacitance, substantial ripple current handling, and a 3,000‑hour endurance at 85 °C, making it suitable for power supply filtering and bulk energy storage in commercial and industrial electronic equipment.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for power systems.
• Snap‑in Terminal, Radial Can Package — Snap‑in mounting type in a radial, can snap‑in package (φ30 × 50 mm), suited for secure chassis or PCB mounting where robust mechanical connection is required.
• High Ripple Current Capability — Rated ripple current of 5.720 A at 120 Hz (low frequency) and 6.578 A at 50 kHz (high frequency), supporting continuous AC stress common in power conversion and filtering.
• Endurance and Temperature Range — Specified for 3,000 hours at 85 °C with an operating temperature range of −40 °C to 85 °C, enabling stable long‑term performance in elevated ambient conditions.
• Electrical Loss and Leakage — Dissipation factor (tan δ) of 0.30 at 20 °C and 120 Hz and a measured leakage current of 2,320 µA, allowing engineers to predict loss and standby current behavior.
• Compliance and Packing — RoHS compliant and supplied in tray packing for streamlined handling in production environments.

Typical Applications

• Power supply filtering — Large 12,000 µF capacitance and high ripple current capability make this capacitor suitable for smoothing and decoupling in regulated power supplies and DC bus circuits.
• Bulk energy storage — The combination of high capacitance and 50 V rating supports bulk charge storage for voltage stabilization in power conversion and backup circuits.
• General‑purpose industrial equipment — Engineered for general‑purpose use, the LLS1H123MELB meets endurance and temperature requirements common to industrial and commercial power electronics assemblies.

Unique Advantages

• Sustained high‑temperature endurance: 3,000 hours at 85 °C ensures predictable lifespan under continuous ripple and DC bias at elevated temperatures.
• Robust ripple handling: 5.72 A (120 Hz) and 6.578 A (50 kHz) ripple current ratings reduce temperature rise and extend service life in high‑stress power circuits.
• Large bulk capacitance in a compact can: 12,000 µF in a φ30 × 50 mm package provides significant energy density for designers constrained by board or chassis space.
• Wide operating temperature range: −40 °C to 85 °C supports deployment across a broad set of ambient conditions without derating outside the specified range.
• Predictable electrical characteristics: Specified tan δ and measured leakage current allow accurate modeling of losses and standby current in system designs.
• Manufacturing friendly packing: Tray packing facilitates handling and placement in mass production environments.
