LLS1H472MELZ

The LLS1H472MELZ is a snap-in terminal aluminum electrolytic capacitor specified for general-purpose applications. It delivers 4.7 mF (4700 µF) capacitance at a 50 V rating in a φ22 × 40 mm radial can package.

Designed for durability in elevated-temperature environments, this part provides long ripple-endurance performance and is suitable for designs that require bulk capacitance with snap-in mounting and RoHS compliance.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) rated at 50 V, tolerance ±20% (at 120 Hz, 20°C).
• Package & Mounting — Snap-in terminal, radial can (snap-in) package with dimensions L: 4.0 cm × D: 2.2 cm (φ22 × 40 mm), tray packing for mass production.
• Temperature Range — Rated for operation from −40°C to +85°C.
• Endurance — Specified to withstand rated ripple current for 3000 hours at 85°C (endurance criteria: capacitance change within ±20%, tan δ ≤ 200% of initial spec, leakage current ≤ initial spec).
• Ripple Current — Specified ripple current handling: 3.02 A at 120 Hz (low frequency) and 3.473 A at 50 kHz (high frequency).
• Leakage Current Specification — Leakage current I ≤ 3√(C·V) µA after 5 minutes application of rated voltage at 20°C (C in µF, V in V).
• Loss Tangent (tan δ) — Maximum tan δ of 0.30 at the 50 V rating (measured at 120 Hz, 20°C).
• Environmental Compliance — RoHS-compliant.

Typical Applications

• General-purpose electronic circuits — Specified as a general purpose capacitor for designs that require 4.7 mF at 50 V with snap-in mounting.
• Board-mounted bulk energy storage — Snap-in radial can package provides bulk capacitance in a compact footprint for board-level energy storage needs.
• Elevated-temperature designs — Suitable where operation up to +85°C and long ripple-endurance (3000 hours at 85°C) are required.

Unique Advantages

• Long ripple endurance: Rated to withstand rated ripple current for 3000 hours at 85°C, helping maintain capacitance and electrical characteristics over extended use.
• High capacitance in compact package: 4700 µF in a φ22 × 40 mm snap-in can delivers substantial bulk capacitance while conserving board area.
• Measured ripple performance: Specified ripple current values at both low frequency (3.02 A at 120 Hz) and high frequency (3.473 A at 50 kHz) for predictable thermal and electrical behavior.
• Clear electrical limits: Leakage current formula (I ≤ 3√CV µA) and tan δ limits provide verifiable acceptance criteria for quality and screening.
• RoHS compliance: Conforms to RoHS directives for environmental and regulatory requirements.
• Secure snap-in mounting: Snap-in terminal radial can package facilitates stable board attachment and mass-production tray packing.
