LAK2D821MELB45ZB

The LAK2D821MELB45ZB is an aluminum electrolytic capacitor in a snap‑in, radial can package offering 820 µF capacitance at a 200 V rating. Designed for general‑purpose power and industrial equipment, it delivers high‑voltage support with extended endurance in elevated temperature environments.

Key value propositions include a high working voltage (200 V), a long rated lifetime at elevated temperature (2000 hours at 105°C), and safety features for abnormal overvoltage conditions—making it suited for equipment exposed to voltage fluctuations.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 200 V DC rating for energy storage and smoothing in higher‑voltage designs.
• High‑temperature Endurance — Rated for 2000 hours at 105°C, meeting the LAK series endurance criteria after D.C. bias plus rated ripple current is applied.
• Snap‑in Radial Can Package — Robust snap‑in terminals and radial can construction for secure panel or chassis mounting and reliable mechanical retention.
• Loss and Performance — Tangent of loss angle (tan δ) specified at 0.20 max (120 Hz, 20°C), supporting predictable dissipation characteristics.
• Ripple Current Capability — Rated ripple currents of 1.99 A at 120 Hz and 2.388 A at 100 kHz to handle AC ripple in power conversion applications.
• Leakage Current Specification — Leakage current defined as I ≤ 3√(C·V) µA after 5 minutes at 20°C, enabling designers to estimate initial leakage behavior.
• Safety Features — Pressure relief vent and improved safety measures for abnormally excessive voltage to reduce risk of dangerous failure modes.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Operating Temperature Range — −25°C to +105°C for use across a broad thermal range.
• Physical Size — Dimension approximately L: 4.5 × D: 3.0 cm (φ30 × 45L), for planning board and enclosure layouts.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple suppression in high‑voltage DC power supplies where 200 V operation and elevated temperature endurance are required.
• Industrial equipment — Energy storage and decoupling in industrial systems exposed to voltage fluctuations and higher ambient temperatures.
• Power conversion stages — Use in AC/DC and DC/DC stages requiring robust ripple handling (specified ripple current at 120 Hz and 100 kHz) and long‑life performance at 105°C.

Unique Advantages

• 200 V rating for higher‑voltage designs: Enables use in circuits operating up to 200 V DC without requiring series stacks or alternative capacitor types.
• Long elevated‑temperature lifetime: 2000 hours at 105°C provides predictable aging and end‑of‑life expectations for thermal‑challenging installations.
• Measured ripple performance: Published ripple current values at 120 Hz and 100 kHz help designers size capacitors for expected AC stress and thermal dissipation.
• Quantified loss characteristics: tan δ ≤ 0.20 at 120 Hz, 20°C gives a clear parameter for estimating dielectric losses in system thermal budgets.
• Safety‑oriented design: Pressure relief vent and series safety performance reduce the risk of hazardous failure under abnormal overvoltage conditions.
• RoHS compliance: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for regulatory and end‑product environmental considerations.
