LLS1V103MELZ

The LLS1V103MELZ from Nichicon is a snap‑in terminal, aluminum electrolytic capacitor in the LLS series, designed for general‑purpose electronic use. It provides 10 mF capacitance at a rated voltage of 35 V with polarized radial can construction and snap‑in mounting.

Engineered for durability under ripple stress, this part withstands 3000 hours of rated ripple current at 85°C and is RoHS compliant, making it appropriate for designs that require reliable bulk capacitance and sustained ripple handling within its specified temperature range.

Key Features

• Capacitance & Voltage — 10 mF rated capacitance at 35 V for bulk energy storage and smoothing in polarized circuits.
• Package & Mounting — Radial can with snap‑in terminals for secure PCB installation and straightforward mechanical retention.
• Temperature Range — Operating temperature from −40°C to +85°C to accommodate a wide range of ambient conditions.
• Endurance — Rated to withstand 3000 hours of D.C. bias plus rated ripple current at 85°C; after the endurance test capacitance remains within ±20% of initial value, tan δ is ≤ 200% of initial, and leakage current is within the initial specified limit.
• Ripple Current Capability — Rated ripple current of 3.75 A at 120 Hz and 4.313 A at 50 kHz to support applications with significant AC ripple on the DC bias.
• Electrical Loss and Leakage — tan δ (max.) at 35 V is 0.35; leakage current follows the datasheet formula I ≤ 3√CV (μA) after 5 minutes at 20°C.
• Tolerance & Polarity — Capacitance tolerance ±20% and polarized construction; observe correct polarity in circuit designs.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Size — Length × Diameter approximate dimension: 5 cm × 2.2 cm (radial can, snap‑in).

Typical Applications

• General‑purpose circuits — Use where a polarized aluminum electrolytic with 10 mF/35 V is specified for bulk capacitance and ripple handling.
• Power supply filtering — Suitable for smoothing and energy storage in general‑purpose power circuits requiring rated ripple current endurance.
• Industrial and consumer equipment — Applicable in a wide range of general‑purpose electronic assemblies that require durable snap‑in electrolytic capacitors within the specified temperature and voltage limits.

Unique Advantages

• High ripple endurance: Rated for 3.75 A at 120 Hz and 4.313 A at 50 kHz, supporting sustained AC ripple under rated conditions.
• Proven long‑life performance: Withstands 3000 hours of rated ripple current at 85°C with controlled changes in capacitance, tan δ, and leakage current per datasheet endurance criteria.
• Snap‑in radial package: Mechanical snap‑in terminals provide reliable PCB retention for demanding board assembly needs.
• Clear electrical limits: Specified tan δ and leakage current formula (I ≤ 3√CV μA after 5 minutes at 20°C) enable predictable design margining.
• RoHS compliant: Conforms to 2011/65/EU and (EU)2015/863 restrictions for lead‑free manufacturing requirements.
• Compact bulk capacitance: 10 mF in a radial snap‑in can provides significant energy storage in a compact footprint (5 cm × 2.2 cm nominal).

Why Choose LLS1V103MELZ?

The LLS1V103MELZ delivers a combination of substantial bulk capacitance, defined ripple current ratings, and long endurance under rated conditions — characteristics that make it a practical choice for general‑purpose power and energy‑storage roles in electronic designs. As part of Nichicon’s LLS series, it offers predictable electrical behavior (including defined tan δ and leakage current limits) and RoHS compliance for contemporary manufacturing requirements.

This part is suited to engineers specifying a polarized aluminum electrolytic with 10 mF at 35 V that must sustain ripple stress at elevated temperature (85°C) over extended periods. Its snap‑in radial construction simplifies mechanical mounting and board retention for assemblies that require robust, long‑term bulk capacitance.
