LASW6151MELB25

The LASW6151MELB25 is a Nichicon LAS series aluminum electrolytic capacitor in a snap‑in terminal (radial can) package, rated 150 µF at 420 V with ±20% tolerance. It is a general‑purpose, high‑voltage capacitor designed for applications that require compact sizing, elevated temperature capability, and robust ripple handling.

Key value comes from 105°C endurance (2000 hours), high ripple current capability across low and high frequencies, and built‑in safety features for use in environments prone to voltage fluctuation.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance rated for 420 V DC with ±20% tolerance.
• High‑temperature Endurance — Specified for operation from −25°C to 105°C with 2000 hours endurance at 105°C under rated conditions.
• Ripple Current Performance — 820 mA at 120 Hz (low frequency) and 943 mA at 10 kHz (high frequency), supporting significant AC stress in power circuits.
• Low Losses — Tan δ (DF) of 0.20 max at 20°C, 120 Hz for stable dissipation characteristics.
• Leakage Current — Specified leakage current of 750 µA, with datasheet limits and recovery behavior defined after voltage treatment.
• Snap‑In Radial Can Package — φ30 × 25 mm (L: 2.5 cm × D: 3 cm) snap‑in construction for secure PCB mounting in high‑current or vibration environments.
• Safety Features — Pressure relief vent design and abnormal voltage tolerance as documented in the LAS series safety performance specifications.
• RoHS Compliant — Manufactured to meet RoHS requirements.

Typical Applications

• General Purpose Electronics — For use where a high‑voltage, snap‑in electrolytic capacitor is required as a bulk energy or smoothing component.
• Equipment in Voltage‑Fluctuating Areas — LAS series is specified as suitable for equipment exposed to abnormal or fluctuating voltages.
• High‑Temperature Power Units — Suitable for power modules and systems that operate at temperatures up to 105°C and require long endurance.

Unique Advantages

• High‑Voltage Capability — 420 V rating enables use in elevated DC bus and high‑voltage power circuits.
• Robust Ripple Handling — Measured ripple currents at 120 Hz and 10 kHz provide predictable thermal and lifetime behavior under AC stress.
• Compact Snap‑In Form Factor — φ30 × 25 mm case and snap‑in terminals deliver a space‑efficient, mechanically secure mounting option.
• Long Endurance at Elevated Temperature — 2000 hours at 105°C with defined limits for capacitance change, tan δ, and leakage current ensures stable long‑term performance.
• Safety‑Oriented Design — Venting and abnormal voltage tests documented in the LAS series reduce risk under fault conditions.
