LLS1E103MELZ

The LLS1E103MELZ is a Nichicon LLS series snap-in aluminum electrolytic capacitor offering 10,000 µF capacitance at a 25 V rating. Designed for general-purpose power applications, this radial, can-type snap-in capacitor delivers bulk energy storage and smoothing in systems that require high capacitance in a compact package.

Key engineering attributes include an endurance rating of 3000 hours at 85°C, a wide operating temperature range of −40°C to +85°C, and substantial ripple current capability at both low and high frequencies—making it suitable for continuous-duty power electronics and industrial equipment.

Key Features

• High Capacitance: 10,000 µF (10 mF) provides significant bulk energy storage for smoothing and decoupling in power supplies and converters.
• Rated Voltage: 25 V DC rated voltage suitable for a wide range of low-voltage power systems.
• Ripple Current Capability: Low-frequency ripple current 3310 mA (120 Hz) and high-frequency ripple current 3806.5 mA (50 kHz), supporting sustained AC loading conditions.
• Endurance at Elevated Temperature: Life rating of 3000 hours at 85°C when subjected to rated ripple and DC bias, providing predictable long-term performance.
• Electrical Losses: tanδ (DF) = 0.4 (measured at 20°C, 120 Hz), useful for evaluating dissipation in AC environments.
• Leakage Current: Specified leakage current of 1500 µA, enabling conservative leakage budgeting in designs.
• Package & Mounting: Snap-in, radial can (φ22 × 35 L), tray packing for production assembly; polarization must be observed in circuits.
• Environmental Compliance: RoHS compliant for designs requiring restricted-substance adherence.

Typical Applications

• Power Supply Smoothing: Bulk filtering and smoothing in general-purpose DC power supplies, leveraging 10,000 µF capacitance and 25 V rating.
• Industrial Power Electronics: Energy storage and ripple handling for converters and motor-drive auxiliary circuits, using the specified ripple current capability and 85°C endurance.
• Backup and Hold-Up Circuits: Short-term energy hold-up and decoupling in systems requiring sustained capacitance and defined leakage characteristics.

Unique Advantages

• Substantial Bulk Storage: 10,000 µF capacitance reduces the need for multiple smaller capacitors when large charge reservoirs are required.
• Robust Ripple Handling: High specified ripple currents at both 120 Hz and 50 kHz support a range of switching and line-frequency conditions without immediate degradation.
• Proven Endurance: Rated for 3000 hours at 85°C under rated ripple current and DC bias, allowing predictable lifecycle planning for thermal environments up to +85°C.
• Compact Snap-In Form Factor: Radial, snap-in can (φ22 × 35 L) simplifies secure board mounting for through-hole assemblies in production environments.
• Design Predictability: Clear specifications for tanδ, leakage current, and capacitance tolerance (±20%) aid accurate simulation and BOM engineering.
• Regulatory Compliance: RoHS compliance supports deployments in markets with restricted-substance requirements.
