LAR2D471MELZ30

The LAR2D471MELZ30 is a 470 µF, 200 V aluminum electrolytic capacitor in a snap-in radial can package from Nichicon's LAR series. It is a snap-in terminal type designed for general-purpose applications that require bulk capacitance and robust high-temperature performance.

Key value is delivered through its 105°C permissible overvoltage design and endurance: the part withstands 2000 hours of rated ripple current at 105°C and incorporates safety measures to reduce short incidence under overvoltage (rated voltage × 1.5). The component is RoHS compliant.

Key Features

• Electrical characteristics — 470 µF nominal capacitance with ±20% tolerance and a rated voltage of 200 V provides substantial bulk storage for general-purpose circuits.
• High-temperature endurance — Rated for an operating temperature range of −40 °C to +105 °C with endurance testing of 2000 hours at 105 °C under D.C. bias plus rated ripple current.
• Ripple current performance — Rated ripple current values of 1.48 A at 120 Hz and 2.22 A at 50 kHz; frequency coefficients apply (for 200/250 V: 50 Hz = 0.81, 120 Hz = 1.00, 50 kHz or more = 1.50).
• Safety performance under overvoltage — Designed to reduce incidence of shorting when subjected to overvoltage testing at 1.5× rated voltage (limited current = 1 A), with specified passing criteria for pressure relief behavior.
• Loss and leakage limits — Tangent of loss angle (tan δ) max 0.15 for 200–400 V at 120 Hz, 20 °C; leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20 °C (C in µF, V in V).
• Package and mounting — Radial, can-type snap-in package for secure PCB mounting and simplified insertion in assemblies.
• Regulatory compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose assemblies — Bulk capacitance for circuits that require 470 µF at 200 V where snap-in mounting and 105 °C endurance are needed.
• High-temperature environments — Use in equipment or locations that demand operation up to +105 °C and long-term ripple endurance (2000 hours at 105 °C).
• PCB snap-in installations — Radial, snap-in can package facilitates secure mounting and straightforward assembly in systems using snap-in terminals.

Unique Advantages

• Long high-temperature life — 2000 hours of rated ripple current endurance at 105 °C supports durability in elevated-temperature designs.
• Overvoltage safety design — Engineered to reduce short incidence when exposed to 1.5× rated voltage, improving reliability under abnormal conditions.
• Measured ripple capability — Specified ripple current values and frequency coefficients allow designers to size capacitors against expected ripple profiles.
• Robust electrical limits — Defined tan δ and leakage-current limits provide predictable aging and performance metrics for design validation.
• RoHS compliant — Meets applicable RoHS requirements for restricted substances.
