LLS1H472MELB

The LLS1H472MELB is a Nichicon LLS series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It provides 4.7 mF (4700 µF) capacitance at a 50 V rating with ±20% tolerance for general-purpose electronic applications.

Designed for robust ripple handling and extended endurance, this component targets equipment requiring bulk energy storage and smoothing within a −40°C to +85°C operating range, and is supplied in tray packing for mass production needs.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) rated at 50 V with ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current Capability — Rated ripple current: 3.01 A at 120 Hz (low frequency) and 3.462 A at 50 kHz (high frequency), enabling effective handling of AC components in power circuits.
• Dielectric Loss — Tangent of loss angle (tan δ) specified as 0.30 maximum at 20°C and 120 Hz for the 50 V rating, supporting predictable ESR/DF behavior.
• Leakage Current — Specified leakage current of 1450 µA (and series-level leakage criteria I ≤ 3√CV after 5 minutes at 20°C as per datasheet).
• Endurance & Reliability — Endurance: 3000 hours at 85°C with rated ripple current applied; capacitance change and tan δ limits defined by the LLS series endurance specification.
• Operating Temperature Range — Rated for −40°C to +85°C operation as part of the LLS series.
• Package & Mounting — Snap‑in terminal, radial can (φ30 × 25L dimensions / approx. 3.0 cm diameter × 2.5 cm length), supplied in tray packing for production assembly.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose Electronic Equipment — Bulk capacitance and 50 V rating for general‑purpose smoothing, decoupling, and energy storage needs where snap‑in mounting is preferred.
• Power Supply Filtering — Rated ripple current values make the capacitor suitable for filtering and smoothing applications within DC power supplies operating up to 50 V.
• Industrial Controls and Instrumentation — Extended endurance (3000 h at 85°C) and wide operating temperature range support long service life in industrial environments.

Unique Advantages

• High bulk capacitance at 50 V: 4700 µF provides substantial energy storage in a compact snap‑in can, reducing the need for multiple smaller capacitors.
• Robust ripple handling: Dual ripple ratings (3.01 A at 120 Hz and 3.462 A at 50 kHz) give predictable performance across common power frequencies.
• Defined loss characteristics: tan δ = 0.30 (max) at 20°C/120 Hz for the 50 V version supports design calculations for heating and ESR-related effects.
• Long endurance under load: 3000 hours at 85°C with rated ripple current applied aligns with designs that require sustained reliability at elevated temperatures.
• Production‑ready packaging: Tray packing and mass production status simplify procurement and assembly for volume manufacturing.
• RoHS compliant: Meets RoHS requirements for environmental compliance in global product builds.
